So a few days ago I was using my ASUS laptop as usual, but I had to get up to grab something. It seemed I lifted the computer wrong or something, because the whole thing suddenly shut down. When I loaded it back up, everything was normal; except that I could no longer use my mouse, or any other USB device. When I plug them in to any of my 3 USB ports (even the one on the other side of the computer which I never use), the computer makes no acknowledgment of any change. No sound, nothing pops-up on "My Computer", nothing.
I've done nearly everything I could find on the internet, but it still won't work. The USB drivers show up on device manager, but they still don't work right even after disabling and re-enabling, uninstalling and reinstalling, or updating. I even tried a complete reset yesterday, but the USB port STILL won't work.
I talked to a computer repairman, and he says that it's because of a virus and the only way to fix it would be completely reinstalling Windows, but I want a second opinion before I try anything too drastic.
