So... I have small issue with my PC. It's less than 2 years old and this has been happening for a while but to make this short sometimes when i turn the computer on after post it just goes to black screen on which the computer sometimes restarts, sometimes it will turn off and than turn back on and sometimes i need to restart it with reset button. After i reset it or it reset itself i boots normally. I cleared CMOS yesterday because i though it was my overclock doing it. But nothing it still happened this morning. I tried everything i could, Reinstall Windows, Use alternative GPU, Cooling, no overclock, use alternative boot methods, playing with CSM in BIOS because that does weird stuff as well when enabled.

Here is YT link of video I made about this issue: https://youtu.be/YklgWnagFE8

Thank everyone for their advice in advance.

I have corsair HX850i, It's 850W; Voltage is +12 at 70.8A and -12 is at 0.8A. And on the side note this issue was happening with my old PSU as well. So i gone out to buy new PSU thinking it's a PSU issue but still happening even with new PSU.
