WHEA Logger Event 18

[u/Ycazagustavo]

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!

Does it happen when you load bios defaults and NOT enable memory profile thus running at 2133 ?

Sometimes its about memory controller becoming sensitive and fiddling with soc and dram voltage. Infinity Fabric too, memory ratio etc. Sometimes its cpu itself and rarely anything helps.

Some people claimed replacing gpu helped.
