Windows 10: all web browsers freeze and crash windows 10

All of my web browswers - Edge, Opera, Chrome, Firefox - will freeze and then crash on my Windows 10 OS build 18363.1256 v1909 installed 2020.05.13. Needless to say, this is maddening if I can't depend on any of the web browsers, so I can only assume its the OS or the computer. It doesn't make sense, but they all crash multiple times a day, regardless of which one I run. HELP!

Windows 10 crashes while using web browsers

I cannot figure out why my Windows 10 *seems* to crash while using web browsers. I am not 100% sure whether web browser cause it but my PC has always crashed when using a web browser. My PC crashes while I use Firefox, Chrome and Opera and I think it happens when I open a few tabs (4-5) at the same time. PC freezes (no black screen, no blue screen, just freezing). It seems that crashing is caused by web browsers and is not related to hardware because I run Prime95 for ~15 hours and my PC didn't crash. I also run memtest86 for 3 hours and without any errors. How do I troubleshoot this issue further?

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?
