I've recently changed the power supply of my computer and when I boot up I get an error message "CPU is unworkable or has been changed. Please recheck - CPU SOFT MENU".
When I press F1 it starts windows normally but after about 2 or 3 mins. it reboot itself and back to the error message. I have a Abit IC7-MAX3, Intel P4 2.40ghz. Please help.
