Built it in August 2010.
Everything worked just fine with the exception of the GPU, that sometimes would overheat because the fan would somehow go to 0 RPM! And temps would climb to 102C before some kind of auto shut down.
No longer boots since May 10th, 2011.
When I turn it on, it keeps turning itself on and off, as if it were flashing. Everything lights up, all fans, GPU fan, you can hear the HD lit up, but then it all shuts off right away every 2 seconds or so. I have no idea what this means.
Before this happened, the system would completely shut off out of the blue. Mostly occurs when I'm browsing the internet. I can't remember if it shuts off when I'm doing anything else. It would do this for several days and then one day it just didn't reboot anymore.
It's not the GPU though, I placed a new one in there to see if it'd help but same problem. I also placed my GPU in another comp, works just fine.
