Windows 10: 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 11PC Specifications: GPU gigabyte R69xt gaming oc, CP

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.

 

Game crashing all the time / PC freezes sometimes

Since about a month I have the problem that a game (Grand Theft Auto V) is crashing all the time. Sometimes the complete PC freezes too so that it displays the old image e.g. a few minutes ago (completely unresponsive, only restarting the PC helps). The time is not predictable, when it crashes. At one time it crashes after five minutes, another time it crashes after half an hour. But one thing is sure - it will crash.

I have contacted the Rockstar Support and they say they can't help me anymore. Things I did asked by the Rockstar Support:

• reinstalled the game and Social Club multiple times
  
• deleted game files in AppData/Local/Rockstar Games/GTA V and Documents\Rockstar Games\Social Club
  
• deleted C:\Program Files (x86)\Steam\steamapps\common\Grand Theft Auto V\GTAVLauncher.exe and restored via Steam option Verify integrity of game files
  
• DISM.exe /Online /Cleanup-image /Restorehealth and sfc /scannow multiple times
  
• uninstalled another app, which should be responsible for network timeouts/blocking
  
• switching to story mode/second character
  
• submitted the export of msinfo32 including crash reports to the support
  
• changed firewall settings
  

Things I tried myself:

• played in Safe Mode
  
• changed graphics settings
  
• removed OC
  
• updated to latest Nvidia driver (436.15)
  
• updated Windows 10
  
• checked the event log, but there is no entry
  
• executed memtest86 without problems
  
• made a stress test with FurMark without problems
  

I don't have expierenced similar problems in other games/apps.

System configuration:

• i5-6600K
  
• 16 GB RAM
  
• Nvidia GeForce GTX 780
  

Temperature is always OK.

Launcher.log from GTA V writes something like:

How can I find the cause of this error?
