Here's my specs:

MSI K8N Neo Platinum
AMD Athlon64 3200+
512mb x2 corsair valueselect RAM
IBM/Hitachi Deskstar SATA 7200rpm 160gb x2 Raid 0 config
Toshiba DVD-RW
Samsung SCSI CD-RW
BFG GeForce6800
Antec 350w PSU (3.3v: 28a, 5v: 35a, 12v: 21a)
Windows XP SP2
No Overclocking.

Here are the problems I encounter:
1. explorer randomly crashing (reboot fixes)
2. LAN cable shows "unplugged" for 1 second, then "plugged in and working" but internet connectivity dies, and system slows down. Fixed by powering down and cold-starting.
3. Occasional file corruptions. For example, unzipping a file and isntalling a program it might say the file is corrupt.

The History:
The cause may all be an old GeForce2 card which I used to have in the machine. When I first built it 2 months ago I had it running an Asus GeForce2 GTS card and the machine was HORRIBLY unstable. It woudln't even START 3D video games. Just as I was about to pull it and buy a 6800, there was a very loud "POP!" from my machine. I immediately powered it down and pulled the card and the PSU. I inspected both but found no problems. I bought a 6800 and put it in. The machine ran beautifully.
However, the problems stated above started happening occasionally.

Thinking it was the PSU, I got rid of my "Ultra" over-rated 500watt and bought a true-power Antec 350 (actually rated better in amperage). This is running now but the problems seem to continue.

ALSO. When my machine was first running the BIOS had defaulted to keeping the CPU "loosely" around 60c which I didn't even notice and it got up to 67/68 under load at times! I changed the settings and it now runs around 45-50. The worst temp i saw was 69 and that was only for 1 second before I shut the machine off.

So. My question is, WHAT'S THE PROBLEM? Is it the PSU (still underpowered?). Is it a fried MOBO? Is it a damaged CPU? Is it a weirdness from having a RAID0 config?

I'd appreciate ANY help.

THANK YOU!!!!

Oh PuLEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEZE! How in the hell can you think a 350 watt PSU will run this. My my calculations you are right on the <A HREF="http://www.jscustompcs.com/power_supply/" target="_new">border!</A>

Sony DRU-510A - Yellowtail Merlot

I just swapped out the 350 for a 450 Antec (SmartPower 450). Problem got WORSE!

I started unplugging unecessary parts - no good.

I pulled one of the RAM sticks and the system gave me a "microsoft cannot determine the activation status of this machine" and then logged me off! (it's a legit copy, btw)

Swapped sticks and it went into VGA mode and froze on the desktop!

Put both sticks back in, rebooted and it worked... for 5 minutes then bluescreened.

Plugged the DVD-R back in so i can do a backup and that's where i'm at now - it's working but i don't know for how long.

I talked to some buddies and we think it's a MOBO problem. The GeForce2 must've killed something on the mobo..???

THIS IS SO IRRITATING!!!!!!

Damn! Loud noises are not good! Look carefully around the capacitors on the MB. Any black spots, rounded top or split ones? Any stuff oozing out anywhere? Also look around the AGP slot for arcing. Are all the rail voltages still good? 3.3v,5v, 12v? As a last resort start completely over.

No visible damage anywhere: psu, old videocard, or mobo.

The voltages, according to MSI Core Center are:

1.5v vcore
3.25v
4.97v
12.08v

and steady.

apps are crashing constantly.

could it be my raid0?

Just a thought...

i keep talking about the raid 0 config (due to read/write errors and pauses), but then what caused the POP? And what does the hard drive have to do with the faulty video card?

HMM... 3 psu's and everything stripped out.. must be the RAM or the mobo.
