Okay, I recently had a bad motherboard supposedly. I took it to bestbuy and they said it was a bad mobo, but the funny thing is that my usb drives were showing up as not recognized right before my computer would start to freeze and restart auto. the monitor would go into hibernate than turn on again. the keyboard/mouse would freeze and stop working. I did a RMA on newegg and am hopefully going to recieve my new mobo/ same brand next week. These are my specs. AMD ATHLONXP 3200+ WD 80 gb HD Maxtor 20gb HD Corsair 2x512 mb Dual Chan Gigabyte Socket 939 MOBO nforce3 Nvidia FX5500 I was wondering what if the usb showing up not recognized could crash a computer. oh and also when i have a usb device connected to my computer it wont go to the windows xp screen..
