I must have nothing plugged in the USB slots when I power up the PC otherwise it just freezes after a few minutes. It is no problem if I plug something in after the PC has booted into Windows but this is annoying because both my mouse and my keyboard are using USB connectors. My motherboard is an ASUS P5KC socket 775 and I have an q6600 as a processor and 4GB of DDR2 RAM. Do you know what the problem could be?
