Over the past month my PC has been doing some weird stuff, such as random blue screens, not logging into windows, display driver not responding, and the on board NIC disappears and then reappears. All of this is sporadic and I cannot reproduce the issues with any confidence. Sometimes the PC runs great for days no issues.
By swapping parts with my other computer I believe I narrowed it down to the Motherboard or the PSU. Both are about 3.5 years old, and I am a little rough on them with constant folding@home or FPS games.
I tested with OCCT in an attempt to figure something out and noticed the 12 volt rail is hanging out at 11.84 during the OCCT CPU test. As soon as the test ends it jumps back up to 12.04 That test is just CPU, it is not even using my video cards. I never noticed this before, but honestly the computer has been running great for years so I never looked. The funny thing is according to my Kill-A-Watt wall plug the computer is only pulling like 400 watts during the test.
Do you folks think this dip in the 12v could explain all the weird stuff? Should I look into a new PSU?Right now everything is running at stock speeds and I have removed my second video card to try and narrow down the list of possible causes.
