My keyboard won't work on my desktop, even other keyboards won't work at all, what's the deal?

Well recently my keyboard would just turn off at times and I'd just move the wire a bit and it'd start working again but today it just completely stopped working and even when I try to use another keyboard it won't work at all. No lights come on for caps lock, num lock, or scroll lock. Can someone help... show more Well recently my keyboard would just turn off at times and I'd just move the wire a bit and it'd start working again but today it just completely stopped working and even when I try to use another keyboard it won't work at all.
