Computer troubles

Hi, my computer will not recognize anything that gets plugged into it. My monitor doesnt get recognized or anything you plug into the usb ports or the mouse or keyboard slots will not be recognized. Does anybody know why this is happening? Or how to fix it? Thanks.

Does it power on at all? Do any of the LEDs light up? It could be so many causes that covering them all is difficult without more precise information.

take it to the shop.

yea everything turns on just fine all the drives open up, just non of the ports seem to work

Reinstall Windows.

Which Windows version is it? Is this a new system or one that’s been running a while and just developed problems?
