Computer resets randomly?

Hello people better than me with computers!

Here's the problem. I noticed a game I was playing was running like shit. It's been running fine for years. In a fit of "i dunno lol" I installed new video card drivers.

Now instead of running like shit, my computer resets itsself every so often when it feels like it, but it only seems to happen when I have a 3D game running.

My google-fu is weak, but most of the topics on the matter talk about either a virus(Sasser, scanned and not detected) or overheating problems (It's fucking winter, and my computer is running at ~45 degrees most of the time). I opened up the box and cleaned out the fan and all that just to be sure, and made sure everything was connected tightly.

I'm using Windows XP, and my Graphics card is a GeForce 6600 (lol). I'm sorry if this isn't alot of information, I can contribute more. Just not sure what is relevant.

　　　　　　　　　 （　´∀｀）　＜　you have a serious hardware compatibility there mah boii , i sugest you just unplug the card try to see if it lets you go in with the normal motherboard card , i have a similar issue long time ago with and aladin pro video card when switching from w98 to xp ,the card was incompatible with xp so maybe thats your case

Thanks, I'll try it out.

but if he's used it fine for years, this wouldent just magically happen

I'd say download a ram checker and check for faulty ram. 5 times out of 6 this kinda weird behaviour is caused by faulty ram and yes they do degrade over time.

I hope you did downgraded the driver and after you tried and saw that it did not make a difference you post here.

Thank you all for the help.

I did downgrade my driver again before posting here, but it made my computer run very choppy, like before I upgraded it. I changed it back and everything's been fine for a few days, all of a sudden it reset it again.

I downloaded a program to check if it was the ram(I think), but it didn't seem to indicate any problems with it. And yeah, this same computer with this same video card and same everything else has been running the game(s) fine for years. Now all of a sudden it started shitting itself.

I've tried downgrading it a little more now, and it seems to be running fine. WE SHALL SEE
