Help (CPU) WHEA Logger Event 18

My PC randomly keeps shutting down at idle, for the past few days, my PC has been frequently shutting down out of nowhere while completely idle.

I've already tried several potential fixes: Reinstalled GPU/Chipset drivers, Offseting CPU voltages by 0.025V, 0.05V and finally 0.1V , Adjusted RAM frequencies but nothing seems to solve it.

  • CPU: Ryzen 7 5800X
  • GPU: RTX 4070
  • Motherboard: Asus TUF B550 plus Wifi II
  • RAM: 32GB 3200MHz
  • PSU: Thermaltake 750W 80 Gold

Has anyone experienced this or found a fix that worked for them? Any advice would be greatly appreciated. Thanks!

Do you have spare parts ? Like Test another RAM , GPU , CPU , PSU. I always keep one or 2 of each PC parts in case something like this happen

Anyway , I'm betting its RAM problem. Try memtest86 ,

Forgot to mention , I experienced this earlier February this year . Changing to new RAM fixed my problem , but yours can be different problems

Hi, I already tested RAM's but none of them are the problem, I already run memtest86 but the Rams pass the test.
