It will do this either after a month since the last time or just before Win 11 lock screen or only a few seconds after bushing the power button.


Reseating My CPU seems to delay the power crashing by a random amount.


I have now changed to an MSI B450 Gaming Pro Carbon. Yet. Mobo this morning. it has not lost power. Yet.

I'm now looking to do a Warranty claim on my mobo. anyone have some help would be nice.

Overheating CPU would do that. A bad motherboard would also. This is also common with underpowered GPUs but I hardly think a 700-750W would struggle with a GTX1080.


ADDED: I'm amazed you got Win11 to run on a 2600. Are they even supported for Win11?

I don't badmouth others' input, I'd appreciate others not badmouthing mine. *** More below ***




Due to the above, I've likely revised posts <30 min old, and do not think as you do.
