This just started happening after my sister decided to use my computer while I was mowing the lawn and she claims she didn't do anything but that's obviously BS. Now, every couple minutes when I'm just doing whatever the mouse suddenly slows down then stops despite me moving it around and a noise plays, like doo doo doo doo then a similar noise plays and the mouse works again. It's so freaking annoying and I can't find anything in Processes that might be causing it. I tried restarting my computer and had no programs open at all and it was still doing it. I checked my startup and there's nothing there that can be doing it. I have no freaking idea what the problem is. I did a scan with the newest Norton virus defs and it found nothing. What the heck is the problem? I'm going to start backing up stuff now on my secondary hard drive then I guess I'm going to format if I can't figure this out. I hate my sister!
