I have an Asus P4P800e deluxe with a 3.0ghz intel hyper threading CPU.\nMy computer has been working for months. I have a mouse, printer, and\ncard reader plugged into the usb ports. I plugged in a usb data cable\nfor a cell phone and began to down load ringtones. Everything was fine\nthe first night. THe next day I attempted the samething and my\ncomputer froze. I went to reboot and it did nothing but say "system\nfailure, cpu test". I swapped the CPU into a friends computer and it\nworked fine. Does anyone have any suggestions?
