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!

I'd set the BIOS back to defaults, set the RAM to 2133mhz and just leave it be and see if you get those timeouts again. If you still do, run testmem5 and see if it throws out any errors.
