Ahh My computer keeps restarting for no reason at all, help!

Lately, whenever I try to run a game or an anti-virus program, my computer randomly turns off. I don't know if its a hardware problem or a virus, but I can't run scans without my computer turning off to find out, and for some reasons, certain games cause it to turn off too. I have tried bringing back my computer to stock, but that didn't help, and I am running prime95, and I don't have any errors there either oc'd or stock.

Any suggestions?

could be, but I have a pretty new one that i only got in October that's been fine till now and I don't have much stress on it considering it's a 550w psu with a basic rig

I've tried housecall, all that does is take forever and not detect anything, and my psu is an antec truepower that's ok, but I will return it and just get a modular psu if you guys say that's the problem. I recently ran spybot and that detected something (kinda makes me wonder why I spent money on mcaffee when that didn't find anything), but the problem still continues, I know that you know a lot about computers anoobis, so I think that you may be right on the psu. But I can't tell right now, I am going to let prime 95 run for at least a few more hours before deciding to rma my ram, and my reason for thinking it's my ram is because it's no longer stable at the previous speeds it could reach, and this is done with less than 2.4 volts, so I don't think I fried it (considering I have the dominator fan on my super talent, I modded it) but I can't tell until prime95 is done

Right now I can't use firefox, I used to love it, but now for some reason, whenever I click on the firefox link or try running it from other ways, it just doesn't show up at all in task manager and nothing happens, re-installing did nothing. So right now I am using opera, which is actually quite nice, and still a lot better than ie, but firefox was a bit more user friendly and compitble with websites etc.

As for my motherboard, the vrm is capiciter less, as I have the asus crosshair, so I don't think that's the problem. I am not sure whether my ram is the problem or not, because I can run prime95 for hours without any problems with the ram underclock, but stock speeds, sometimes I get errors, sometimes I don't, and I never run anything in the background while gaming or benchmarking, even with a dual core, I still don't like the lag and I want clean benches whenever I do them. But a damaged motherboard may likely be it, I don't think I have pushed it too hard, but I have tried ocing at different ram speeds and timings for a review I'm working on I get lots of restarts. The thing that worries me is that once I forgot to drop down the ht mult to 3 from 5 and I ran my ht at 290, my computer ran fine and then it suddenly restarted, going in through the bios to lower the settings, I noticed the ht mult was at 5 and immedietly lowered it. But that doesn't explain why I don't get failures when my ram is underclocked and at stock I have gotten them once or twice. Of course, when I oc, I always under run my ht, so the ht may be it

I'm just wondering, doesn't windows have an integrated hardware diagnosis program that can tell you if something's damaged, if not, is there any program that can?

well right now, I know at least that its hardware, because prime95 fails after a while if I pressure the ram, but I am still worried about the vrm, as I have had quite a bit of oc failure as part of my testing, but there isn't any visible damage, so I am hoping it's just the ram, if it's the mobo too, I just return the parts to their manufacturers for a refund (if possible), sell my x2 on ebay, and just get a conroe instead, otherwise, I am going to try and find a nice deal on this ram right here, right now I'm really pissed I didn't get it on the black friday sale when it was only $250

Proven ocer to get high frequencies with low voltage

Thanks, I know one of my ram sticks are bad now, because one stick lasted for hours on prime95, but the other doesn't last 5 minutes if I run them individually

I know there are, but I can't get either windows based utility to work, and I don't have a floppy drive for memtest (not sure why it doesn't work on cd's, I have tried)
