Mouse problems! >.

Okay, i switched my computer on this morning and the mouse seemed fine when i moved it, but as soon as i stopped moving the cursor went crazy for a few seconds bezzing round my screen, it would stop but when i move the mouse and stop it again it would do the same thing, i tried un-plugging it then plugging it back in, no joy, so i restarted, the tried un-plugging it again, now i have plugged it back in for the second time the cursor won't even move, lol! I have tried doing the same and re-plugging it but it still won't move :P, any help?

Oh, i have fixed it :P, i just fully shut down the computer re-plugged it then started up again, sorry for the inconvenient post :P.
