Hey, got a little problem here...

My USB drives have been working perfectly fine for a long while now. Until my USB ports stopped working [apparently?] It might be software or something im not thinking of... but last night my mouse was working intermittently, while working windows would suddenly make the High-low noise like a device had been removed, and then a few seconds later make the low-high noise like one had been added, and my mouse would resume working. Well today, it was working for a while and then made the high-low noise and my mouse and laptop cooling pad are both not functioning. Im hoping my USB ports arent just broken... any ideas?
