My Windows 7 computer started shutting down seemingly randomly recently. Basically, within a 10-120 seconds from hitting the power button, the computer just powers off as if I unplugged it. No BSOD, no error message, nothing.
I put the tower on it's side to check the connections of all the cables inside. WHen I hit the power, it booted! Great, I thought. I stood it up and it shut down again. I put it on its side and it ran flawlessly again.
What is going on? Loose connection somewhere? I really don't want to keep it on its side forever.
- The tower is on its side.
- The side cover (which is now oriented on the top) is off.
- The motherboard is now parallel to the ground.
- Booting to a Windows 7 install disk still failed.
I'll check the HSF next...
