My PC randomly freezes, sometimes it happens after hours of use, sometimes, not even 5 minutes past boot. Weirdly, something still seem to be working somehow, like today after freezing the PC played the sound notification for web whatsapp, but got no response from mouse/keyboard and the windows clock remained frozen. Ctrl + Alt + Del also unresponsive.
It has been happening for months, but now the freezes are getting more frequent. Also, when it started, all I had to do is press the reset button, and everything would be back, now when I do that the PC doesn't boot. Everything seems normal (pc lights and sounds), but the monitor stays in the "no signal" mode. I suppose this means No POST.
So I end up having to take it out from power and waiting for a few minutes before turning it on again.
So far I've tried:
- Clear CMOS (Caused me some "inaccessible boot device" trouble, that's now solved)
I'm not sure what else I can do to diagnose the issue. Every suggestion is welcome

So far I've tried:
- Windows memory diagnostic tool (normal and advanced)
- Memtest 86+ (7 passes 0 errors)
- Cleaning the memory and switching the slots
- Stress test with AIDA64 (no freezes)
- Clear CMOS (Caused me some "inaccessible boot device" trouble, that's now solved)
