Windows 10: Major PC issues crashes/freezes when loading games

Most of my issues come from trying to start up Fortnite. The game will either begin to load and completely lock my computer up, or the game will load and if I tab out or try to close my game it completely locks my computer up. I've looked everywhere online to figure out what to do and I'm just not tech savy enough to figure it out. I'm getting quite a few errors and warnings in my event viewer I will post a few of them below. I also just installed a new motherboard with new RAM. Everything else seems to work perfectly fine. I've updated all drivers, BIOS and what not.Running Windows 11 P

Need assistance with game crashes and freezes after changing PC location

I recently relocated my stationary PC, and since then, I've been experiencing issues with both Steam games and other games. Specifically, when launching Steam games, the loading screen freezes after a few seconds, causing Task Manager to crash, ultimately requiring a PC restart. Additionally, non-Steam games tend to close abruptly after 2-3 minutes of gameplay.

Error Message: No specific error messages are displayed; however, the loading screen freeze for Steam games prompts Task Manager to crash.

System Information:

• Operating System: Windows 11
  
• PC Specifications: GPU gigabyte R69xt gaming oc, CPU i5 13600k, etc.
  
• Game Platform: facing issues with Steam games or other gaming platforms like epic games
  

Actions Taken: I have already taken the following steps to address the issue:

1. Updated all drivers.
   
2. Attempted various troubleshooting methods found online.
   
3. Updated the BIOS to the latest version.
   

Despite these efforts, the problem persists, and I am unsure about the root cause. Any guidance or assistance would be greatly appreciated. Thank you!

 

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.
