Game crash from nowhere

Hey PieTeRForEvEr​ 

I have moved your thread from the Polish forums to English, since you've posted in that language. 

From what you described, the CPU temperature itself (around 46C) is actually quite low, so it’s very unlikely that the shutdown is being triggered by overheating. These points point more toward a crash or system-level interruption rather than a thermal issue.

A few things worth checking next:

• Make sure Windows is fully up to date
• Do a clean GPU driver install 
• Disable any overlays or background tools, for this you can simply perform a clean boot of your PC 
• Remove any CPU/GPU overclock 
• Check Windows Reliability Monitor
  • Press Start and type Reliability Monitor (alternatively, press Win+R, and type perfmon /rel) - This can give a clue if it’s the game, driver, or something else shutting it down.
• Lastly, open Command Prompt as admin and run, to run system file checks:
  • sfc /scannow
• Then restart PC and test again.
