CMOS resetting itself?

[Tugberk]

Hello everyone. I have R6 1600 / B350M mortar system. A few days ago the power went out. After that, CMOS is resetting itself every day. There was no other electricity interruption. Thanks for your help

My gut is telling me the battery might've went bad for some reason. But a power outage shouldn't have caused that.

 

If it's cheap enough for you, I'd try replacing the battery first.

If that doesn't work, then the power supply may have been damaged from the power outage. Was the PC on a surge protector?

I will try this as soon as possible.

I hope, this will solve the problem. I have Seasonic S12ii-620.

No there isn't surge protection. Also afterwards, the power went on and went out quickly (so sorry for bad english ). Maybe it was because of it.

Having the power come on and off quickly(a brown out) is more dangerous to a PC than a total loss of power that lasts for a while. This has the potential to damage the power supply and other components in the system. Replacing the battery will help us determine whether or not you need a new power supply, motherboard, or both.
