Windows 10: Computer crashed once and then my games kept crashing over and over stating a 'GPU crash'...

Today I tried playing Fortnite and after a couple of minutes in game, my computer just randomly restarted on its own. Then, every time I tried to play the game, it would crash after a couple of minutes in game. It would tell me that I had a GPU crash. Here's an image of what the crash reporter says.Then I went to Marvel Rivals and it kept crashing as well. I updated my drivers and it kept crashing. I restarted my computer in safe mode, I closed some background apps, I did an antivirus scan and nothing showed up, but both games keep crashing. It seems like there's an issue with the GPU but I ca

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.

 

Crashes during gaming and followup crashes on restart


I was having similar issues on windows 7 X64, recently updated to 10, issues are still here. Computer will crash during gaming, sometimes it lasts a while or crashes pretty immediately, afterwards, attempting to start the computer will trigger many crashes during startup.

Errors all appeared to be in the kernal, suspect a hardware issue. PSU? Memory? Possibly GPU?

Steps I have taken:

-Complete reinstall and update to ten
-Update Motherboard Drivers
-Update GPU drivers
-Update DX
-Memtest (Pass) (considering running again)
-ChkDsk (Pass)
-SFC (some errors found that cannot be fixed)
-Reseated/Cleaned memory and GPU
-Dusted and cleaned inside of case
-Tested power supply (slightly undervolt i.e. 4.9 on 5 lead 11.9 on 12 lead)

Steps I have not taken

-Flash BIOS
-Throw computer out of the window

Please find attached the requested dump logs,

As a side note, windows ten doesn't appear to blue screen, it just crashes.

Please help!

Thank you for your attention.
