[SOLVED] USB port not working, pc not shutting off properly

[Sirazulmonir]

Hello there! I'm new here and pardon my mistakes.

Recently I'm having some strange problems. There were some power outages and for some reason, I didn't have mu UPS connected. Now I'm having a weird problem. My USB wifi adapter isn't working with any usb port. The ports themselves are outputting 5 volts(i.e. if I connect my phone it charges but windows doesn't detect it as usb device.) My mouse and keyboard are working. Strangely enough, if I disconnect them and reconnect them again while pc is turned on, they aren't also working anymore. Here are some more problem going on:

a)pc isn't shutting down properly. windows shuts down but pc itself not shutting down(example fun running etc)
b) cannot uninstall any driver (the green progress bar keeps on going forever

Here's what I tried

1. tried booting in safe mode
2. uninstall and reinstalling drivers in safe mode

What worked for me :
removing the CMOS battery and reinstalling it fixed the problem. But it comes back.

Combining all the problems, can anyone suggest to me what's going on? I'm assuming it's a motherboard related problem or the cmos battery is dead. But I can't just buy a cmos battery now, as I'm writing this during covid 19 pandemic.

Any suggestions will be highly appreciated. Thanks

Define power outtages, was it during a thunderstorm, weather storm in your area ?
Is the computer directly connected to the wall or power strip surge connector ?

Also it might help, if you start backing up whatever important files you need.
Next get a iso of your current os redownloaded, perform a clean install and start off fresh.
If the same symptoms start happening again after the reinstall it might be a mobo problem.

Hey, thanks for the response. Yes, the power outage was during a weather storm. The computer was connected directly to the wall without any protection.
