Overheating isn't an issue: Xigmatek heatsink and HAF X case.
About a week ago, I woke up, and my PC has shut down. I tried to start it back up, and the computer attempted to (LEDs/fans started up), then it powered down. I tried to start it up again, and 0 response.
I decided to test my PSU and used the Corsair video where I disconnected it from my Mobo, bridged the cable via a paperclip, and found the PSU working fine. I reconnected it to the Mobo, and this time my computer successfully restarted. However, the computer's clock has been reset to 1/1/2010 at 12:00 AM.
Since then, it's happened every 2-3 days, sometimes when I'm using it (minute tasks: preparing a powerpoint for my honors thesis defense//no auto save, lost a lot of work) and sometimes when I'm asleep. It has yet to shut down while I play CODMW2 or Bad Company 2. Temperature readings are all fine.
Every time I have it shut down, I have to go through the same process as I mentioned above. For instance:
1. Random shut-down mid essay
2. Try to restart: LEDs/Fan briefly turn on, then off. Reattempting the start up after this has no effects.
3. Turn off PSU
4. Disconnect PSU and Mobo; Reconnect
5. Power-up works. If it doesn't, I go through 2-4 until it works again.
Every time, clock has been reset.
Any ideas? I was wondering if the battery in my Mobo could be dead, and this could be the result?
