You can also reset your CMOS. on the motherboard is a set of pins, with a jumper connecting two of them. it looks like the little jumper on the back of a hard drive that you set for master, slave, or cable select. The pins will be marked on the board run, and reset CMOS. put them in the reset position, reset, and then replace them. Sometimes this will work.
