My PC restarts quite often. it happens mostly in these cases:
1) When switching the HDMI cable between the computer screen and my TV. Specifically, I hear the humming the second that I unplug (this is the most common cause)
2) When running heavy graphic programs (e.g. Photoshop)
3) When touching the PC case accidently, even slightly.
I took the PC to a lab today, the guy there found high PCU temperatures and replaced the fan, it's apparently cooler now, but the problem persists.
I attached a TXT file with the link to the speccy report, and also a zipped Sysnative report.
