Computer will not read flash drives

My computer has stopped reading flash drives. It's a windows 7 machine and either wont show the drive or shows it with 0 bytes used and 0 bytes free. I've tried 3 different flash drives that all still work on other computers just fine and can't figure out what the issue is. I've uninstalled it from device manager and reinstalled it and tried assigning it a different drive letter, no luck. Other USB devices work with no problem. Any help would be much appreciated as I'm out of ideas.

 

When that happened to me, I used a different USB port in back - that solved it.

Might work for you.
