So I came back for Easter and found out my desktop has magically started to shut itself down, no error, no BSOD, no warnings come start up. The screen just goes black and shuts down. I thought it could be related to dust so I cleaned the case out and it hasn't seemed to help anything. Virus scans seem to be clean.
The shutdowns are random and happen whenever they feel like it seems. The only thing I think it could be is that Vista has decided to cause problems for some unknown reason. This would make sense since it will give me an activation warning saying that it isn't activated. This seems to be a problem with OEM installations and I'm in the process of downloading the most recent service pack to see if it fixes it.
CPU: Athlon 64 X2 5600+
Memory: 6gb of Corsair OCZ (not sure atm)
Windows Version: SP2 v.286
Again I'm thinking it's my windows version since it was installed when SP2 was about to release or was when it was still in beta. It is odd though since it's never given me issues before.
I've had my fair share of fun with video cards so I'm 99% sure it isn't the 4870. The computer shuts off as if the power had been cut.
Right now I'm having fun trying to uninstall the prerelease SP2 and reduce Vista's HDD usage. Whoever designed the winsxs folder and thought it was a good idea to make it untouchable is someone I really hate.
Try booting up an Ubuntu live cd and runing some tests. I don't know if it includes something like Prime95, but they usually have everything in those CDs.
Don't just rule out hardware yet.
