so I've been having a weird issue for the past year or so that I've struggled to deal with. It started with Cyberpunk and my PC having continual freezes/crashes. At first I thought this was down to the shitty state Cyberpunk released in, and some of it definitely was, but then I started noticing these crashes in other games that were moderately graphically intense (no issue on games like Fall Guys or Hades). I went through endless NVIDIA driver updates and changes, and while I noticed different issues with different drivers, the core issue of game freezes and occasional reboots continued (no blue screens, and sometimes the PC just locks up AFTER I've finished playing a game - i.e. there is no demand on the GPU at that time, but it still locks). Something is ****ed.
In some desperation, I started fiddling with my other components - mainly the RAM. I have 2 x 8gb sticks and they run at slightly different speeds, which shouldn't be an issue because they both default to the slower speed. I tried taking one stick out and still had the issue, I tried the other stick and it didn't even boot for some reason, I swapped them around and dusted everything off and wala - no issues for about a month. Then, the freezing started again.
So I opened the case, used some compressed air with everything disconnected to de-dust the interior of the case (there was minimal dust in there anyway, but it was still a bit dusty). I cleared up my fans, tried to make sure the PSU outlet was clear and gave the thing a bit more ventilation and what do you know - we're rolling strong again.
So I can't work out if I have maybe a RAM issue (seems doubtful despite being primary susptect), a MOBO issue (I still want to update the BIOS as I'm sure there must be a later version), a CPU issue, or a PSU issue. Its not an HDD issue as I of course already reformatted and re-installed everything and instantly had the problem. Could it really be a little bit of dust or MAYBE slightly poor airflow that's been giving me these headaches? I've never experienced anything like this before so thought I'd put this long sorry tale out there to see if anyone else has / has some insights.
