Windows 10: Crashes, Freezes, weird stuff happening.

Hello, so I have a few issues with my PC.It started with random GPU 100% Fan and Black screen randomly.They blue screens and freezes. The Event Monitor always pointed at something with Nvidia.So I replaced my GPU with one from a different Vendor. I don't have the fan issues anymore, but had blue screens and crashes after that as well.After a few months of that, I decided to completely delete windows and made a fresh, clean installation of Windows 11.Now, there are A LOT more crashes, freezes in games when I ALT + TAB out, 3-4 blue screens whenever I restart my PC.Chrome crashes every

:)

 

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?

 

all games crash!

ive watch my temps and both the cpu and gpu are within normal ranges. when it freezes it simply freezes the image and stops the sound. i must reboot to get back to windows.

 

Weird stuff happening

Alright, recently I got my PC and now it decides to act weird like supposedly now "The Audio Service Is Not Running" which is the first time that ever happened, internet decides to not work, "WIndows Firewall not on" which I believe it is on, can't see the event log and loads of other things.

When I try to plug a USB flash drive into my computer it wouldn't show up so I looked in device manager and Windows decides to say "Windows is still setting this device up" or something like that with the error code 56. Tried everything to fix it but it won't work. No clue why this is happening when it worked perfectly fine before.
