Help!!! Burnt out CPU??????

[Wisecracker]

t doesn\t hurt the computer. All the pins do is cut power to the Cmos allowing it to reset itself. No harm will come by powering the system on with the jumper set.

mmmm . . . NO! 😀

At best by leaving the *clear CMOS* jumper pin engaged the CMOS would reset the computer to factory defaults at each boot. All BIOS changes would dumped from CMOS every time you restarted the box.

More likely would be no boot, a checksum fail or bad authentication id.

Most importantly, a motherboard can be damaged if the computer is powered on with the jumper in the discharge CMOS position.

Nice catch on the pins. Have a good day!

It may have been that the one pin was just a ground so you didn't have any issues. It's that second pin that is an important pin that is causing problems. Hope the mechanical pencil trick works for you. Be very carful though. The pins a delicate and can break fairly easily.

which 2nd pin are we talking about here? Shall I try to straighten all of the bent ones or just that 2nd pin?

 

[Grimmy]

Both... try to get them lined up as close as possible. But if you can't, or break a pin, just get another MB. No need to create more headaches. 😀


EDIT:

I just noticed that there is either a strand of hair (thread of the carpet?) or wire near the right side inner corner. Make sure you get all debree out of the socket as well. Can of air should do the trick.

Thanks for letting me know grimmy..i've got rid of that wire. But I'm struggling to sort out the pins. They seem to be lapping over each other. I'm not sure if the pins might have totally broken. Here are a few closeups of the damaged pins:-

Getting a new mobo is not an option at the moment as firstly I was on a very tight budget when i bought parts for this pc and secondly we can't be 100% sure that its a faulty mobo

Oooph... man thats looking a bit hairy. I'm kinda gritting my teeth. That was one of the fears or thoughts going through my head when I first stared at the socket array when I got my dad's system, wondering what I'd do if I accidentally bent one of them.

I dunno.. if you can RMA that MB, try, or just bite the bullet and get another one.

Or if your sure you can bend it back, it might be okay, but that looks bent out of shape.

Edit:

This video, is prolly one thing everyone should see, who has never put a 775 socket system together:

Kinda sorry if you never saw it.

A good friend of mine has offered to test the CPU, RAM and Graphics card, so that we can eliminate these from the problem...will be going over hopefully at 6pm (GMT) and will let you guys know the outcome later in the evening. Till then, if anyone can help or advice on repairing these pins, I will be so much grateful.

Thanks!

GL on that. I'm guessing the CPU/RAM should be okay, as well as the video card.

The video I linked, if you watch it, does tell you to reject the MB if it has any signs of bent pins.

Tried to edit it sooner, but it seems I'm having some connectivity problems.

Thank you for that link...its very interesting...although a little to late though

Anyway I went down to my friends and the CPU, memory and Graphics Card are fine, so yes its the motherboard.

I'm still not gonna give up on this. I will order the mobo and till it arrives, I'm gonna mess about with the pins on this one instead to see if i can fix it.

8O Oh NO!! I've tried sorting the pins out and after having a go at straightening them, I decided to connect the pc to see if i had solved the problem.

Instead of some power, now I get absolutely no power...NOTHING AT ALL!! Have I killed the PSU too? or is it just the mobo?

Just to clarify, I have connected everything correctly, such as power ATX cables and 4-pin connector. There is no led light as before on the mobo. 😳

Do you have a warranty on your MB? If so, then RMA. If not youll have to buy another outright. Don't try assembling with bad/bent pins or you might end up damaging your CPU.

Good Gawd man... STOP! :lol:

Just get another MB. I guess you can't RMA it for a replacement? Not sure what you can do in the UK.. I guess your over seas from where I'm at.

You can try this trick to see if you PSU is okay:

Tutorials | Turn on PSU without motherboard - the 'paperclip trick'

Basically, you want the PSU switch turned off. Then you connect the black and green wires on the 24 pin molex together, then switch it on, and the PSU should come on. Then switch it off. I ended up using a regular wire, like what the PSU uses for your molex connectors, instead of a paper clip to test my older 20 pin PSU.

I've had all these before, well just not on a core2.

I have used the cmos reset jumper with the psu plugged in, i have even tried to switch the pc on with it still in the clear position. Nothing happens, the pc doesn't get power, which might be the problem Ripperuk is facing right now, just check to make sure the cmos jumper is back to 1-2 not 2-3. No problems with my pc that this could be linked to, and i've used this jumper many Many times.

My mom bought a pc recently : a celeron.
I put the pc together myself. After taking it apart and putting my cpu in I noticed 3 bentish pins. My p4 seemed to be giving weird problems, but that was probably to do with not formating windows and just randomly putting in about 6 new parts the pc didn't recognize. After putting the celeron back in I noticed that the pins seemed straight again?

Atleast you know now that your cpu,ram, and gpu are all fine. If you could try another 775cpu in your mobo(with different ram) then you would be able to tell for sure.

I'm guessing you are just doing a general reply, but just in case your not, let me fill you in on his situation a lil better.

As far as having the jumper to clear the bios out, it could prevent the system from powering up, but that wouldn't be for all brands of mother boards.

First off, he is using a 775 socket system. So the pins are on the mother board socket. So the pins are not on the bottom of the CPU.

Here's a pic of the bottom of a 775 socket CPU:

Back side of Core 2 Duo

And if you look closer at the pictures he provided, the pins are basically an upside down V shape. To bend those back perfectly, I'd say be very hard to do, even with the mechanical pencil I'm afraid, and will prolly break if bent too much.

Now the pins on the underside of your moms celeron, which I'm thinking its a 478 CPU, the pins would be easier to straighten out.

I think the best thing for him is to get another mother board, before anything worse can happen. Hopefully there is nothing wrong with any other component that he has, besides the mother board.

I hope you understand how fragile the pins are on a 775 socket mother board.

Thanks for all your advice guys, but there is no need for it!!! I took the mobo down to the shop and the technical support spotted the damaged pins immediately. They instantly stated that since its physically damaged and its been over 2 weeks since i bought it, they can't take it back, blah blah..

After a good argument, the guy said he'll go and test it and look if the pins are a problem. I waited a good 10mins and he comes back out saying the "mobo is fine and working perfect!!" He still added that even though its working they can't accept it back as its physically damaged.

There was no point arguing and i bought it back home. I rebuilt the whole system and there it was, working once again. I think he went inside and straightened the pins, hence fixing the short in the mobo. I checked them and they look almost the same as the rest, so he must have done something to the pins.

Anyway, I'm happy that my system is working once again 😀

But thank you again for all your help!

Anyway guys, I'd be grateful if you could jump to the following thread to help me on the original issue, which caused me so much hassle in the first place:-

Grimmy : I know what i was talking about, like I said, my mom bought the celeron recently, its a 775 socket with the pins on the mobo. The pins looked bent on the mobo, not the cpu.
