I got my old mouse out of the trashcan and plugged it in. The computer started normally. The mouse still acted jumpy and messed up. This makes me think it was a poorly timed hardware problem that coincided with my redirects/AntiVir virus thing? When I plug in the new USB mouse the computer still starts to a blank screen, or goes to a screen that says there is a problem with the mouse. If I start and then plug in the USB mouse everything works normally.
