I need a new computer bad, but for now while I save up for a good one I need some help. For some reason my USB ports keep ejecting themselves. I thought it could be a cheap USB port HUB I bought awhile ago but it turns out even my Ipod(which was plugged directly into my comp) keeps ejecting itself. Virus maybe? I was thinking of maybe opening up my comp and checking it out maybe tightening the screws around the USB ports. I really have no idea. Any help?
