setup new comp today. xp sp1 installed. 3800 x2 manches-2*512 mb ddr pc 3200 ram- 160 gb sata 3.0-7600gt non-sli. Every time i'm doing something such as downloading the computer freezes up or just reboots in the middle of something. This has also happened if i'm using the usb on the case for transferring data. Idk if i need some driver/ bios/ update suggestions???
