Unique PC crashing issues
Howdy, so I've got a bit of a unique problem on my hands that I cannot seem to identify the source of.
For reference, these are my specs
Zotac Twin 3060Ti
Ryzen 5 5600X3D
16GB DDR4 Oloy Warhawk (running at 2133mhz)
Samsung 970 Evo 1TB
Asus B550m
Around a month ago, whilst playing either Roblox or R6 Siege, my entire operating system would just die. No bluescreen, no automatic restart. The audio would cut, then a half second later the game I was playing would freeze, then another 1-2 seconds later windows and my inputs would become entirely unresponsive until I turned my PC off and on again. A small temporary fix was to just perpetually lower the frame rate/resolution of the game but I play siege semi-competitively so eventually that started to become a hinderance.
Eventually I turned off the discord overlay and hardware acceleration and that yielded good results for a few days, but then the issues returned.
A few days later, I got the idea that it could just be my PC overheating (even though GPU and CPU temps never went above 70C) so I decided to crank my GPU fan speeds up to 100% and that solved my issues for a few days too.
Then a few days ago, the issues just came back out of the blue while playing Rust. I considered the possibility that maybe it was the SSD because of a certain quirk before the crashes (disk usage would spike to 100% a few seconds prior with 0 read or write speed), so I went and purchased a heatsink for it. Heatsink did nothing except for making my SSD blend in with my white build a bit more lol. I also got the crackhead idea of just taking the panel off my case and pointing my fan straight into it to no avail.
Now I'm reaching my wits end and feel forced to buy a completely new computer if I can't find a fix here.
I've tried an assortment of things
I've ran chkdsk, I've done a samsung magician erase, got crystal disk info which reports a 98% SSD health. I've tweaked with every BIOS setting imaginable (RAID, UEFI, and undervolting my parts just to name a few off the top of my head, also reverted them back to defaults in case I did something that was working against my computer).
I reinstalled windows numerous times, changed my SSD slot back and forth, I even got two different custom windows forks (AtlasOS and Revolt specifically) but no beans.
The only critical log in EventViewer is a Kernel-Power issue (Event ID 41, Task Category 63), and it only displays that there WAS an error and a system reboot took place
"The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."
it only creates the log when I actually turn my computer back on however, its not a log that gets saved prior to the complete freeze.
I'm open to any and all ideas but if I can't find a solution then I'm just gonna bite the moderately expensive bullet and get a new one so here's to hoping someone may be able to recognize or identify my issue.
