When i put my wheel usb into the pc, it normally spins to collaborate and the power light goes green.

Now for some odd reason, i plug it in, and the wheel doesnt spin.. and the power light flashes green..

anyone know what the problem is?

Have you plugged in the power? Checked all cables (also those under the wheel!)? Maybe something became loose...

I had this problem, mine had to go back for repair, (on mine the pedals still registered fine, but wheel wouldn't register (if you turn it nothing happens) in windows or in game)
