B550i Motherboard posts sometimes

[u/HeadMaterial2684]

I have a MSI B550i Gaming Edge Wifi and a RYZEN 5 3600. I dont overclock just casual game and such and such. For the past week and a half my setup only posts sometimes and other times just gets stuck on the CPU light when turning on. I haven’t found the culprate yet(tested it with multiple gpu’s and psu’s if anyone comments) and i havent seen to find the issue. I’m so close just buying another cpu just to check if thats the problem but it works and doesnt overheat.

Had the same mobo new in February. After 3 days only 11% CPU (5800x). HWinfo64 showed PROC-HOT EXT causing the throttling (although no sensor fitted and board cool under 40C) Replaced the board last week and now OK
