Question having frequent game crashes due to "video driver crashing", but I don't think it's related to the GPU

Hi. Second post here. Sorry in advance if it's hard to read. Also, posting specs before I start:

Case: Corsair 4000D
MB: ROG STRIX B550-A Gaming
CPU: Ryzen 5 5600x (x2)
RAM: Corsair Vengeance LPX 16x2GB
SSD: Samsung 970 EVO 500TB
GPU: GTX 1080 Ti, RX 6700 XT
Power Supply: EVGA SUPERNOVA 850 G+ 80+ Gold
Liquid Cooler: Corsair iCUE H100i (240mm)

I've been having this problem ever since I created my PC, but recently, I have been getting crashes not only frequently but with no correlation except that it only crashes on demanding, high FPS FPS games (Overwatch 2, VALORANT, APEX, Escape From Tarkov). It used to crash way less, like I would get them maybe once or twice every few days, but it's become so severe and frequent that I cannot even play a single game without it crashing at least twice. Crashes have the game freeze, then black, then I can't go to another screen, then it has a dialogue with the crash report. The only way to get out and reset the game is the windows+tab key to create a new desktop,
At first, I thought it was my GPU, the 1080 Ti, since it was crashing in Heaven Benchmark. Crashes were NOT due to any temp (recently, sometimes the CPU temp is high; has to do more with the fan configuration), as it could range from about 50 to 85 (80+ probably means it overheated), and there is obviously enough RAM. SSD seems fine, RAM I'm not sure, as I haven't conducted tests on it, and I'm fairly sure my power supply I'm not going above the watt limit (sometimes GPU watt is <100, sometimes 200+). My main problem then lies within either RAM, CPU, or GPU.
I bought an RX 6700XT, did DDU, and downloaded the drivers for 6700XT on AMD's site. Played a few games in shooting range, still crashed, but only after I turned my settings up and around 10 minutes of Apex. It seemed fine until today when I tried to play Valorant, and it crashed not once, not twice, but 4 times during a full game. I lowered my FPS limit, lowered settings, and checked temperatures - all fine. It still kept giving me the error message that my video driver crashed. The only thing that could cause a crash might be my CPU, since it was getting hot recently. However, I changed it for another 5 5600X that I had around, and it STILL crashes. Maybe it could be fans, but I'm fairly sure that it would still crash with lower temperatures. If my CPU or GPU was damaged, I would get blue screens/crashes during normal use (watching videos, playing any other game, editing, etc.), but I don't (had a few due to corrupted windows). Then could it be RAM? I have no extra RAM that work, and they seem to be the culprit.

Here's what I consider suspicious (TL;DR):
Games and specifically ONLY FPS hungry FPS games crash frequently now when they didn't used to. Only crashes during those games and no correlation with each other (e.g., one crash might have high GPU temps and less GPU watt use, one might have less GPU temps but high CPU temps and high GPU watt use). No overclocks.
-I had a blue screen (once) due to MEMORY_MANAGEMENT, and when I tried to use DumpIt, my PC just straight up blue screened the SECOND I pressed Y to confirm (SYSTEM_SERVICE_EXCEPTION). I have not tried it since.
-When I did DDU and rebooted, it was a black screen for a while; did a bunch of resets and finally was able to see the screen when I entered BIOS (it was black, but responsive. I went all the way into my account one time, and pretty sure into Automatic Repair and BIOS at least once). Not sure how it fixed itself, but I learned that was not normal.
-CPU temps are unusually high recently. When I boot up, it is usually in the 60 range when it wasn't before, maybe around 40-50 at most. This could be due to how I changed the radiator fans and moved them to the top to blow air out (they don't cover the whole radiator, so air might be leaking, and the fans on it aren't PWM).
-Motherboard? Possibly? No evidence, but I feel that it's been weird, and I feel the extra RAM I replaced the Vengeance with should have worked.
-Possible malware/virus/using my computer for mining or something? I have no idea how that stuff works, and, again, I have no evidence, just suspicion.
I'm honestly out of ideas, besides significant underclocking in Afterburner, changing fans back, and resetting BIOS and/or resetting CMOS. Does anyone have the same problem or can figure it out? If there's any more info you need, I will gladly provide it.
 
yep. Not sure if it's DDU or my computer, but seems you and I have problems 🙁
Something else I think is suspicious is this all happened AFTER I reset everything by redownloading Windows 11. Not sure if that is the problem, and I'm fairly sure it was happening before; just putting it out there.
 
Well... figured it out myself. Clean installed Windows 11 (downgraded to Windows 10 for that to work, not sure if it's required) and stopped running iCUE software and everything's back to normal. Did not think it was that bad, especially since I've had it for a little bit. Not sure which but both helped a LOT. Pretty sure it was the clean reinstall that did the most
