PC freezes, what is the reason?

Question

Windows

Hello everyone
This is nonsense: The
PC stood for 2 months without use (I was absent) I
used the PC for 3 days, on the 4th morning it didn’t cut it (Everything is spinning, but the keyboard and the monik don’t cut it)
moved it and it bam -
I got it Then I noticed that it it is necessary to move it and it will work (it works without interruption and in general everything is fine). Yesterday he passed out in the middle of the game (no error, stupidly hung and that's it). I cleaned it from dust, it turned on but with tricks - video tdr failure nvidia. I sort of fixed it - took it down and put firewood again, put another power cable from the PSU on the video) everything works, but the button accordion - at any moment it freezes and reboots (without blue)
checked the registry, made a restore point. (it feels like he passed out during the restoration)))
In events - something like an unexpected shutdown of the PC, there is no error code. I watched the whole history, nfiga
loaded the PSU - 1 hour under load and everything is OK, it works. (OCCT). I watched the series, closed the browser and it passed out.
Since the last reboot, it has been working for 48 minutes and it's fine.
What the hell? once it was because of the hard drive, I replaced it and it seems like it’s gone until
now

Answer 1

Memory. Remove, clean the contacts, rearrange the banks in places. Try to work on half the memory. Run memtest.

Answer 2

1. Reconnect your HDD or SSD. It helped me once
. 2. Pull out and insert the vidyuhi again.
If this does not help, then check your disk for wear. If health is less than 80-70, then the problem is in it
