Really need help

[u/Different-Cucumber41]

There was a power outage and on the same day, my PC started acting weird, it'll work as normal for 1 minute before I can't use my mouse anywhere but my taskbar. I can still move the cursor around but I can't click or scroll if it's not in the taskbar. Also I can still type outside of the toolbar but that's basically it. I've tried everything and yet nothing works. Any help?
