So I've been having this problem for a good month or so and it's been really pissing me off. My computer will randomly freeze and I have to completely turn it off by holding the power button (or pressing the reset button). I have literally checked everything: Reliability Monitor, Event Viewer, I went to run and typed in "perfmon/report", I reinstalled windows, I flashed my BIOS then reflashed it thinking maybe the one I used before could have somehow been corrupted. I cannot find any evidence of a log that reports my problem. It doesn't seem to matter what I'm doing (playing a game, watching youtube, transferring files, listening to spotify, etc). Also I'm not sure if this has something to do with it but my motherboard sometimes shows the QCODE 00 and won't boot then I have to take out the CMOS batter for like 30 seconds and put it back in. Also when the computer does freeze I can't push "Caps Lock" or "Num Lock", sometimes I'll be listening to Spotify and my music stops when the computer freeze's so I know the freeze is unrecoverable. I monitored my temps and nothing is overheating, I monitored my cpu, gpu and ram usage, nothing is spiking right before the computer freezes so its not a memory leak. One time it froze 9 times in a row with around 10-20 minutes passing before each freeze and other times I'll go a full 4-8 hour gaming session without a single freeze.
