Windows 10: my system crash's while playing new demanding games

My system crashes when I'm playing demanding games like Fortnite, Diablo 4, and Starfield. its when i hop over to my other monitor to check a guide or when I exit the game at the end of playing. This one happened while i was playing Starfield and tabbing over to google chrome. everything freezes right down to the RGB's in my tower and the picture looks like i paused a movie right when the system crashed.here's the minidump https://drive.google.com/file/d/15UDlud-QSsLr6dspUUyTXjEsozrv79Nm/view?usp=drive_linkThis one was with Fortnite i can not remember if this was a crash or nothttps://drive

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?

 

Desktop PC crashes and shuts down after playing some games for a few minutes.

How demanding the game is does not matter, several high demand games run just fine, the only ones that I know that crash are listed in the OP, Overwatch and Doom are not light games. Overwatch actualy gets the temps higher than any of the other games but
is one I play all the time and never get any crashes.

Just typing that I realize that should be alarm bells, but I would rather play Overwatch most of the time anyway.
