PC Crashin' and Burnin'

Sup /comp/

Anyways, I needs some helps with my PC here. The low down is this,  my pc decided to one day start randomly resetting itself during normal pwnage on the internets. At first I thought that this was some simple over heating going on in the PC seeing how I has a SLI set up in the thing. The computer then still randomly crashes at times so I ran memtest86 on it and the memory checked out to be good and I know that the hard drives are all good. Now I called tech support about this and they said I might have to replace the mother board so they sent me a new mother board and the new mother board doesn't help at all.

Now I haven't done any testing to the video cards but I believe that they are ok. Although, now the computer would shut down in the middle of windows when it's just being idle. Before it was just when I was in some hardcore gaming sessions. Any ideas Anon?

I am going to stop trolling for a few seconds. This only happens like once a year so listen up

You can really have some good times with your computer. You seriously should learn to fix it yourself. Nobody cares about how it runs but you. If you take it to some jackhole and tell him to fix it, it's not going to get done right. Even if you have a father/brother/boyfriend/whatever that you LIVE with who is a Lunix tard and fixes computers for a living, he can't fix it like you can. Even if you're mediocre at best dealing with hardware. Only you use it enough to make a true diagnosis of your computer's health.

Start troubleshooting. Rule everything you can out, then make an educated guess about the source. You know where all the components came from (or have at least a good guess). You know that hard disk failure is probably not the culprit because it's new. Did you install Windows from scratch on it, or did you use some utility to move it from your old disk (like MaxBlast/dd/etc.)? Can you consistantly get your disk to register in the BIOS? Can you make it consistantly fail? If either is true, you found the cause. Try replacing the IDE cable. If that fixes it, you found the cause. Try removing one stick of RAM and see if the problem happens still. If so, take it out and try the other. If still, try one stick in the other DDR channel or another slot. If that still doesn't fix it, you ruled out a RAM error too. Remove all PCI cards but the graphics. Remove all other disk drives. If this doesn't fix it, you've ruled out the possibility of a power drought (not enough power from the power supply causes brownouts that show this kind of behaviour).

Try anything else reasonable you can think of. If all else fails, you have a bad IDE channel on the motherboard. In that case, you need a new motherboard.
