So my friend has a good PC:

asus x570-pro motherboard
5600x
32gb ram
rtx 3070
EVGA supernova 750w psu and a surge protector
running windows 10

He had a scheduled power outage a while ago and it seems like it fried some of his USB ports, it took hours to get his computer to stop shutting itself off due to "overcurrent protection." He finally got it working and now, a few weeks later, there was another power outage and he's having the same problem. When it randomly doesn't detect overcurrent, the motherboard is incorrectly detecting multiple keyboards and mice and bios is only reachable on rare occasions.

Is there a short somewhere? Why are power outages causing this if he has a surge protector, decent PSU, and decent motherboard? He doesn't want to have to buy another motherboard, so any suggestions are good. Different USB ports work when they feel like it so that does help and it restarts constantly so turning it off and on isn't gonna fix it either.

Surge Protectors are not endless protection.

They are designed with components that can absorb up to some given amount of energy. The measurement being Joules.

And the absorption is cumulative.

You can easily find other similar links to read.

Look in Reliability History and Event Viewer for error codes, warnings, and even informational events that were recorded when the various problems occurred.

The objective being to narrow things down a bit to some specific cause: hardware or software. With power problems, as you describe, there could be multiple issues now.

Try running "sfc /scannow" and "dism" to find and fix file corruptions.
