For some time now i've got a problem with my PC - During games or watching videos i had mini freezes. Sometimes the only way to notice them was through the headphones (quick "CRACH" sound). Micro second of unusual sound/mini refresh of video/game and everything was normal again.

Two days ago i updated the graphics drivers to the newest. After an update instead of microfreezes i started getting 1-2sec black screens and sometimes random restarts. I rolled back previous drivers. Didn't help. I decided to clean the whole system disc and reinstall windows (Clean install). Didn't help. I checked cables, changed HDMI - nothing. The current graphic drivers are two updates behind. Random minifreezes are gone, but during watching videos/games PC restarts itself/stops responding (No error).

I didn't know what to look for, so a few stats i thought might be useful:
CPU under stress looks fine. Temperatures normal

GPU temp during Heaven Benchmark (Also i ran it for quite some time to check how it looks like) at ultra - max 60
There is a problem i observed during benchmark that i have noticed during games. FPS drops. The game starts with 6 FPS and then a minifreeze happens and suddently 60+FPS (Same place/same settings). For example - I turn on the game with high details. FPS <10. The games sometimes randomly "refresh" with cracking noise and it jumps to max fps. Turning the game after a reset (Once fps drop happened) used to solve problem. Now with random restarting it's not that easy.

No OC, newest BIOS drivers.

Also... There is one little thing. Cracking noises in PSU. Seems quite unusual compared with my previous ones, but everything worked fine for a year. Just in case i recorded it (From around 8sec mark):

I hope i didn't create this topic in wrong department (As i think that it's either PSU or GPU, but i haven't got enough knowledge to decide which on is it. No idea how to confirm PSU problems as i don't have any other power supply to swap it with mine, but if this is the only way to check it - tell me and i will try to get it somehow). If there is any more information needed - please let me know and i will supply you guys with it
