I will add to the tread again.

Originally my current rig had a G4TI4600 instead of the current 9800pro. One day when my computer froze, I got a little angry as this was the third time it did that in that day, So I decided just to yank the powercord from the powersupply...

Then came a loud BANG. The capacitors on the G4 had blown off completely. I managed to replace them (was increadibly hard to find replacements, had to solder(sp?) two different caps together in paralel to get the right rating for those caps). After that it amazing worked, but now I was stuck with 3 vertical lines on the left side of my screen, and they wouldnt go away. So I replaced it with the current 9800pro that is in my sig. Luckily the powersupply still lives and hasn't given me any problems yet.

Again, you must be thinking that I'm increadibly lucky...

This happened before my water damage story.
 
Has anyone tried to overclock a computer at school and screwed it up?

No, but last year (8th grade), I almost got kicked off of the computers for the year because I went into the BIOS on a school computer.

At my high school, all the teachers have new ThinkCentre (StinkCentre; lol) desktops with Pentium D's, 2GB RAM, and some sort of ATI video card.
 
I forgot to add one of the worst mistakes I ever made: installing Vista on my computer.

About a year ago, I promised myself that I'd never download a Microsoft beta. So far, I've stuck to my promise. I'm even considering using 2000 instead of XP on my computer, as I find that 2000 is more stable and idiot-proof.

on a side note, my school has "new" P4 ovens in SFF cases, those things run real hot, well the tech guy at my school isn't that bright and the password on the bios is just the schools name and the bios thankfully has options for overclocking, I will try it and see what happens one day. BTW the cases aren't well ventilated and only have 1 80mm fan blowing out of the case, the ps dont even have a fan.

Should be a fun experiment...

Shoot for no less than 4GHz. Set the FSB to about 400.
 
My very first build was my parents' system which was just replaced last month. Athlon XP 1800+, 256MB PC2100, 80GB Maxtor hard drive, I talked them into a Geforce3 Ti200 instead of integrated, since I was into games. It was a killer upgrade from their previous rig, which my dad built - a Cyrix 6x86MX PR200 150MHz w/64MB and a SiS 6326 4MB. I assembled their entire XP1800 rig without a hitch, hit the power switch, and the fans spun, but nothing else - no beep. Great. I got real upset (I was only 14 at the time) and so I unplugged all the cables and plugged them all back in, then started her up perfectly. Must have been a tiny bit of corrosion on one of the connections.

I built a system for myself later on, my second build - an Athlon XP 2400+ with 512MB PC3200 and a Radeon 9600. This one started up the first time, and had no problems until a driver problem... I turned both displays off somehow in the ATi control panel and had to wind up reinstalling Windows XP cuz I had no knowledge of booting in VGA mode >_<

My third build was for a friend, he wanted something for music, so I was building him a P4 3.2 on LGA775 with 512MB PC2-4200 and a 160GB hard drive, using integrated graphics and a Sound Blaster Audigy. I ordered him the wrong motherboard - I was trying to get him DDR2, but ordered him a DDR-based motherboard. 🙂 Instead of RMA'ing and losing 15%, I turned this into my next build, and ordered him the correct motherboard.

My rig based on that motherboard was a P4 3.0GHz, two 512MB sticks of Corsair ValueSelect PC3200, and a Geforce 6600GT for PCI Express from Leadtek. Two months after building it, the video card crapped out on me. I didn't know what the problem was, because it was so intermittent. Integrated graphics ran fine, then the 6600GT graphics card would run once every four boots or so. I was angered, and sold off all the parts except the video card, RMA'ing it for a replacement (which I then sold) and I, at the time, blamed the whole thing on PCI Express not being perfected yet (it was a new technology at the time).

So I pieced something together off a forum, my best build so far. P4 2.8 Prescott, same two 512MB sticks of Corsair, and originally a Radeon 9700 Pro. I wasn't getting high enough framerates in my favorite game of the time, which was Need for Speed Underground 2, so I got an XFX Geforce 6800GT for AGP. It clocked higher than 425MHz on the core, but I never really used it much over 410MHz, since the CPU was more of a bottleneck. I got a Zalman CNPS7000-Cu, and this started my love of Zalman heatsinks. I clocked my Prescott to a 250FSB, and it ran at 45C under load at 3.5GHz. I'm 100% serious. This was in an Antec SLK3700-BQE case, with an MSI 875P Neo-LSR. I ran that rig until I sold it to buy a car. What's kinda funny about this rig, at the time I was in a business class at school and for a project, I had my friend take a video recording of me talking about computers as a business person, then building my P4 2.8 rig. It's funny, because like so many others at the time, I didn't know how much AS5 was a proper amount. I put too much on, it oozed off the sides of the CPU, but luckily didn't reach any contacts - just did enough damage to not allow it to boot that time. Undid everything, realized there was too much AS5, cleaned it all up and reapplied a smaller amount... and clocked her back to 3.5GHz. :-D

One of the greatest flub-ups in my history is not one that I did. It was one that one of my friends did while I was with him at school. You guys were talking about overclocking school computers. Well we had an A+ Hardware class, and I was trying to milk more performance out of our slow Celeron D's running 2.53GHz. I got mine running at over 3GHz by clocking the memory down to PC2100 (we were supplied with PC2700) and increasing hte bus speed. Maximum speed I got to was 165FSB, resulting in 3.14GHz (yes, Pi GHz) and so my friend John tried the same. I tested mine Prime95 stable for a weekend, then recommended he try playing around with the bus speed. He didn't exercise caution - and jumped straight up to 165FSB, frying his chip. 😛

I received an XP1700 rig from a friend of mine who I built a 3.06GHz P4 Northwood rig for as a replacement, I wanted to test his "old" XP1700 out, and so I took the heatsink off to look at his chip and get the spec markings. When I put it back on, I secured one clip, then the other - but the first clip came undone in the process. This is the only time I've ever smelled fried processor. There was a burn mark on the underneath side of his processor. I saw the smoke - just a little bit. I didn't like myself after that. haha
 
he mentioned Leadtek, that shot me to a flash back!

i had nearly forgotten the biggest mistake i had made thus far. BUYING VIDEO CARDS ON EBAY IS THE WORST IDEA EVER!

i had recently finished my Prescott Build, (my last build), it was a great computer and i was happy with my 6600GT and was was looking for a lil more power.

i wanted a 6800GT or higher, so began looking on ebay, (now i had never boughten from a person on ebay, only companies, and online retailers) but was assured by this guy that the card was in working order and in fact was the video card he was using to message me. so i buy it. i receive it in good order (thinking great!) so i rip out my 6600GT slam in the 6800GT and to my amazement, it doesnt have 256mb of memory, ITS THE 128mb VERSION! as i read in the bios as my comp starts. (1st. pissed me off) so my comp starts up and i begin to drill this thing with benches and what not.

(2nd to piss me off) its, artifacting. and i was using the right drivers, even changed em a couple times.

so now im sending angry emails to m=this guy asking for my money back and saying ill gladly return the card to him. come to find out this guy had tried to OC this card before he sold it. but not by using coolbits, he tried to OC through the BIOS by cranking up the voltage! HE ADMITTED THIS TO ME! all in all i didnt get my money back.

so now ive got this half dead 6800GT sitting there. The next part is graphic, young ones please look away.

so i take this thing out, take off the HSF and its got thermal pads on it. :twisted: So i clean those off with Isopro and a razor blade, i replace them with some AS5 and put the HSF back on. I fire it up on my pc and right away open up riva tuner, amazingly it opened up the extra shader and the four pipes! (more tragedy) so now with it fully opened i put a pretty fat OC on it and slammed it straight into 3DMark05.it made it about half way through the first test before it went up in smoke.

i replaced it with my lil 6600GT and never looked back. by the way. replacing thermal pads with AS5 is not safe, especially if the pads are thick. never buy used computer stuff off ebay! period.
 
Here's a fun one for you guys. A few months back, I managed to actually rip an Athlon 64 (socket 939) partially out of the socket with the locking mechanism in place. It really was just kind of a fluke, and I'm still not totally sure how it happened.

I was basically building a computer for someone, and the PSU got delayed in shipping, so I put a temporary one in to test all the other components. When I went to change it out, I managed to bump the HSF for the CPU (not even very hard really). I didn't even think anything of it at the time, but the computer wouldn't even put out a video signal. In the process of trying to diagnose the problem, one of the last things I tried was to remount the CPU.

When I took off the HSF, the CPU looked a little odd in the socket. It was a socket 939, and the only thing directly attaching the HSF to the CPU was the thermal paste (AS5 I think). The thing had been pulled up out of the socket on one side, and numerous pins were bent pretty badly. I was afraid that there might be some broken pins as well, and the CPU looked like it was going to have to be replaced.

The incredible thing is, after spending about half-an-hour with a magnifier, pen knife, and very fine pair of needle-nose pliers, I managed to get the pins back into place. The CPU wouldn't go into socket the first few attempts, but I just kept fiddling. When I finally got the CPU to go in, it just dropped right into place with no effort, and the system booted up fine. I did some extensive testing, and everything worked flawlessly.

Oddly enough, the owner called me about three months later due to a lightning strike and I had to replace the PSU that started all this. Since the PSU didn't let the surge get through to anything else in the system, I guess it did alright in the end.
 
Yeah, I remember, and have been around since *before* there were Turbo buttons to push. IIRC, the turbo buttons were only on some 386s and 486s and did not actually "turbo" the CPU but let it run at full speed. The reason that it did not run at full speed all the time wasn't an early version of manual SpeedStep/Cool 'n Quiet but so that your DOS games that were tied to the CPU's clock ticks for timing would not run at warp speed.

My worst- and only- goof-up was that I accidentally connected a FDD's 4-pin one pin off. It was in a ATX dual-CPU server, so I was a contortionist just to reach the back of the FDD. Of course there were sparks, smoke, and a burned FDD and power connector when I turned the unit on, but the rest of the computer was fine. It wasn't on my own computer, so a new floppy and 4-pin end got put in and it runs fine. It was kind of hard to explain how I shot sparks all out the side of the machine to its owner, but he was certainly understanding as he'd did it before too on an 8086 box if I am not mistaken. Now he's much older than I am 😀
 
All of ours were (and to the best of my knowledge, still are) Duron 700s on Biostar mobos with 128MB RAM, running Windows 98. Before that, it was a few odd all-in-one beige PowerMacs, Mac LC2s, and Apple IIe's.

At college, we have a real smattering of old stuff. Here's what I see in the numerous labs. Note that they all run WXP unless noted.

1. PII/400 MHz, 256MB RAM
2. PIII/700, 866, 933 MHz, 256MB RAM
3. P4/1.5 GHz, 512MB RAM
4. P4 1.8 Williamette, 256MB RAM
5. P4 Northwood, 512MB RAM
6. P4 Prescott 2.8E, 1.0GB RAM
7. P4 Cedar Mill 3.4, 1.0GB RAM (some of these run Linux too.)
8. Pentium D 820, 1.0GB RAM (some of these run Linux too.)
9. Motorola/Freescale 7447/700 MHz (MacOS 10.4)
10. IBM PowerPC 970/1.6-1.8 GHz (MacOS 10.4)
11. Intel Core Duo 1.83 GHz (MacOS 10.4)

They retired the PII/233s last year, and replaced them with little Dell OptiPlex SFF units with the 3.4 P4s in them. You can hear those things a mile away. However, the mid-tower version of the OptiPlex with the same chips are nearly silent and you can hear the 6GB HDDs in the PII machines over the sound of the mid-tower units. SFF cases and hot CPUs just don't mix.

I certainly remember as far back as the early 386s, but I can never really brag too much because I started out with Apples. As I recall, the first IIe I had was over $1500 and was less technically advanced that a lot of modern cell phones for around $100. I had the pleasure of a 25Mhz Mac LC next, and it was amazing at the time.

Sorry to hijack the thread BTW. Here's an interesting story to get back on topic:

One of the dumbest things I ever did was crack open an old CRT to see what the inside looked like. This was over a decade ago (I was about 14 at the time), and I just look back and think how lucky I was. I knew not to touch the capacitor, but I didn't have any idea what it looked like or just how dangerous it was. At least I had enough sense to realize that I had no clue what I was doing and put the cover back on the thing.

were you making ape like noises and jumping on the case,while flailing your arms madly ?
ive heard thats a prerequisite to sawing a case in half. 😛

Wot? I do that all the time whenever I'm doing a build. Otherwise you don't appease Zappus the Ape God Of Electronics. Then you're in big trouble. Is there something wrong with that?

:lol:
 
buying hardware off eBay is indeed a bad idea. Now, I think the idea of replacing the thermal pad with AC5 is not a bad idea in itself, you just have to consider that the removed thickness may make the retention mechanism less efficient - so don't forget to compensate for that.
Now, unlocking it and all worked goodusing Rivatuner, that's nice; did you consider trying to resetting the voltage back to default in the BIOS? Because OC + OV = HEAT.

Knowing that, and knowing Rivatuner, had I been in your place I would have kept an eye on Rivatuner's temp monitor (GF6 series have it built in and Rivatuner knows it) during a first benchmarking session, and stopped the rig as soon as the card beat 95°C.

Your f@$k up stems from you being a bit too careless, but also much too violent on the poor card.
 
the card was ruined but still booted up and let you work in windows but as soon as you started a movie or game, down hill from there. i was angry cus the guy lied, first he said he didnt OC it, then he said he used coolbits, then what i asked what clock and memory speed he had it set at, he gave me voltages 8O .

then when i tried to return it to him saying that he falsely advertised, he said it was a done deal and refused to refund for an exchange. (second thing telling me he screwed up the card and dished it off on ebay)

so i popped it to get a lil bit of excitement out of my $1xx silicon and HSF.

what would you have done with a crippled card that cant be returned? but get me straight i would never do this to anyone elses computer. or something that i thought had a chance of being resurected.
 
cant say ive had a 'worst' build.. but ive done a couple dumb things.

1st one was back in college, I was building a "brand new 486/66" box for a friend's dad. Ordered the parts from a local store and put it togther in my room. since he lived an hour drive away I didnt give it to him right away.
so it sat on my desk and got "tested" playing Doom with some friends.
The next nite during a game session. both my box and the new box rebooted themselves. They came back up and we resumed playing. except the supposedly uber 486 box was now Dog slow.
To make a long story short - a power spike came through and fried half the cpu on the new box, but left min untouched. This presented a big problem for me as replacement cost for that thing was $600. And for a broke college student, that was 2x what I had in my savings account.

My friend's dad eventually came down, picked up his PC, bought a new CPU and took it directly to his business and watched me make sure it worked.
Thus I now take great pains to ensure I have adequate power protection


The only other dumb thing that I remember was testing to see if a cpu fan was running by lightly brushing my finger over where the fan blades were supposed to be. the fan was running alright - and srong enough to snap off 3 of the 6 fan blades, and imbed one of them under my fingernail.

The price of replacing the Orb fan was trivial compared to the sore thumb I had for a week afterwards :/

Next time I wont do this in the dim light without my glasses on.

OK, I get your point - well, I would probably have kept the card in a drawer and waited for the 'nouveau' driver to be advanced enough (note: nouveau is the name of a free/open source driver for Nvidia cards under Linux) since one of the programmers intends to include a memory check and bad RAM spots workaround for busted cards. And yes, it would be pretty much useless under Windows.

Now if artifacts come from a damaged GPU, you could have tried disabling pipelines one after the other to see which one is busted and thus, restore the card.
 
I have Had 2 IDE Hard Drives Die (Lucky they weren't mine) :)

The first, was hooked up and put on the outside of my case, then i proceeded to turn on the power and an IC on it exploded and started shooting sparks everywhere. 8O

The Second one was hooked up inside my case and after turning on my computer, it started to smoke and smell, after my friend anxiously tried it in another computer he gave up and went home

The First One was out of a pre-built computer with a void warranty (Case Opened Sticker Broken), i put it back as it was and my friend returned it to the shop, 4 weeks later it was replaced, free of charge and the hard drive was deemed faulty - $0 :lol:

My Second Friend Wasn't as lucky, as he had built his own computer 4 years prior, and had no warranty whatsoever on it and had to buy a new one - $120NZD ($60USD approx?)

A few months later I took my computer into the shop where I had purchased the motherboard, they tested brand new IDE hard drives with it, and not one died, and I found out that what had caused Hundreds of Dollars of Damage was a $1 IDE Cable :lol:

Also, I was given a 133MHz P1 Computer from school, Plugged it In, Turned it on, and then out the back of the PSU Came a Great Big POOF! 8O and out came what smelt like Curry :? (The smell lingering in the room for days), this also happened with the 6 others I ended up taking apart and breaking or using the (3 1/2") 2048MB Hard Drives in other projects
 
Old AT form factor AMD rig (K6 i think... can't remember, it was 1998-ish) built out of random bits salvaged from friends and dead machines...

Plugged the power cables into the mobo backwards...

The Caps on the Mobo ignited, exploded, and shot across the room trailing purple smoke, OOPS 😀

Not noticing the HUGE zalman heatsink slide off the Athlon XP 2200+ that i'd just fitted and wondering what the smell was 😛 Vapourising artic silver smells like crysanthemums...
 
My first eve PC, got all the parts in the evening at closing hours just a day before Christmas came home and started building it up.

2 hours later there it was sitting tall and shiny. Reached to the power button and closed my eyes and pressed it. Dang nothing happened. Opened the case up, made sure all the cables were right and try again nothing. Can't call the store now since they were closed and next day was christmas so no joy for next five days.

So started looking over each and every component and found the PSU was set to 115 V rather than 230 V. Flicked the switch and wolla it was flying like a free bird thorough the air.
 
just ug'd my cpu to an a64 3000. ran it for a few days while I checked out heatsinks. Got me a new hs and while removing the stock heatsink the cpu came with it and bent 30 or so pins.

Oh what a joy it is to straighten those tiny tiny pins.
 
2 stories, one of loss and one of luck:

1. Once upon a time I had a Comodore 64, and for the benefit of those of you whom may have been just twinkles in your parent's eyes back then, the C64 had/has an external power supply we used to affectionately call a brick, largley because it was heavy (the transformer was sealed in resin) and rectangular. Well, I loved that machine, and used it most everyday. One day my cousin visiting for a week asked if she could use my C64. I said sure, and started to set up (as at the time I had to connect to the TV in the living room, and so it had to be set up every time I wanted to use it and take it apart again when I was done). I encourage me to help her assemble the parts together. See, back then most everything was external or plugged into some kind of slot, and everything was meant to be taken apart and put together this way and so the connectors really only worked 1 way if it mattered at all. So I ask her to plug in the brick's connector to the actual C64 unit (again, it's only supposed to go in one way) and went to the bathroom. When I come back I find a burnt small and my cousin asking "Is it supposed to smell like that?"

Well, no, it wasn't. Seems she managed to force the power connector into it's socket turned nintey degrees clockwise somehow and (as later investigation showed) the main graphics chip, which was soldered onto the mainboard and so unserviceable. Lesson learned - don't assume that because it's only meant to go one way that you can't make it go another.

2. Much more recently I bought an external 300MB HDD as a way to move lots of data around between my machines and have some back-up of personal data files. It's pretty nice and it connects via USB and has an external power supply with a pretty long cable. The day it came in the post I was pretty keen to pull a lot of files from the downstairs machine so I could move them to the upstairs and still have the back-up. As such I hooked it up to the USB and went looking for a spare power socket. Turns out we were full up by the machine but I could just reach the one by the aquarium across the room if I sat the HDD on a chair at the end of the USB cable. It starts up fine and I start moving folders in a big lump. So I think to myself: Hmm - seems it'll be a half-hour. Well I'll just pop upstairs for a bit and check my e-mail and such while I'm waiting.

SMART. Very smart :roll: Especially since The WIfe(TM) was out when I set all this up. Cue sunset and 30 minutes later when I hear shouts from downstairs. My wife had come home, and it was dark in the living room and she had come through and run right into the power cord yanking it out of the computer and sending the HDD flying across the room. I come running down to find out what's happening and she's appologizing - luckily she wasn't hurt by my own stupidity and neither was the drive. Considering I may have to do that operation again, the lesson learned would be to babysit starnge setups.
