Windows 10: My desktop randomly crashed and locked, sometimes even the fan speeds up.

I've been facing some annoying issues with my desktop lately. It randomly freezes, crashes, and the fan speeds up without any clear reason. I am not quite sure is it hardware or OS issue. So could you please help me? I didn't take any photos, but you can imagine the screen stays on, but it stops responding entirely, ignoring even attempts to force quit applications.

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?

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.

 

Case fans speed randomly goes up and goes down

I got a tower case and 4 case fans installed. One in the front to suck in air, one one the floor to push air up, one large one on the side to pull in air and one on the back to push out hot air.

I recently did a clean install and had a few freezing problems that was fixed by doing the solutions and bios update but I realized soon after that my case fans speed speeds up randomly and goes back to normal a right after. It's not causing any problems for me other than annoying me, but I'm worried it will damage the fans if this keeps up.

I tried setting the fan speed in BIOS but not sure what to do. I'm also not sure which fans is doing it, all of it or just one, but I watched my cpu fan closely and it didn't seem to change.

My bios is BIOS Version/Date American Megatrends Inc. V1.10, 2018/07/10.
