I started having a strange issue with my computer a few days ago. It runs fine and then just shuts down by itself. This can happen while gaming, browsing or even when the computer is just sitting idle.
When it shuts down, I can start it back up right away without any issues other than the warning that it wasn't shut down properly.
Bit of info on the computer, it's a bit older:
CPU: Phenom II X4 955 Black
Video: Radeon R9 280x
MB: Gigabyte MA79FXT-UD5P
Ram: 2x4GB Mushkin PC3-10666
HD : Samsung 840 EVO 250GB
2 x WD Caviar Black 640 GB
Power: Corsair CX750 (added about a year ago as previous PS had died)
Sound: Soundblaster XFI Elite Pro (I've removed this and the issue persists)
This machine has been problem free up until a few days ago when this started. The only odd thing is that it stopped going to sleep about 3 weeks ago, it was configured to shut the hard drives off after an our of idling.
I don't believe this is a power supply issue as all of the lights on the MD, video card, soundcard all stay on when it shuts off. Power doesn't seem to be lost, it just shuts off.
I used OpenHardwareMonitor to check for heat and the CPU doesn't seem to go about 55C, I think the video card got up to about 69C.
I had tried running check disk on my main harddrive and all I got was a black screen and couldn't get into windows at all. I was able to run SeaTools for dos (short and long tests) and everything passed. I couldn't repair windows, so I figured I'd install windows 10. It packaged everything up into a windows.old folder, so I was still able to get to everything I previously had in windows 7. The machine shut it self off again yesterday though.
Any thoughts?
