Here's what happened: I borrowed our modem so that I could use it on the laptop I borrowed from my friend. When I reconnected the modem to our PC and turned it (the PC) on, I found that the keyboard and mouse don't work anymore. I can't even access BIOS, Safe Mode, etc.
HELP!! WHAT HAPPENED?!! I think it's a virus, ain't it?
I'm using WinXP.
