Your problem should be corrected by clearing your system's RTC RAM, also
known as clearing the CMOS. To clear your system's CMOS, follow these
instructions:

1: Turn off your system, making sure to disconnect the power cord from
the wall or power strip. The green power light on the motherboard should
turn off after several seconds.

2: Locate the circular CMOS battery and remove it from the motherboard.

3: Locate CLRTC (also may be labeled CLR_RTC). This is usually a set of

three pins with a jumper cap, but it may also be two pins without a jumper
or simply a pair of solder points, depending on which motherboard you
have.

If your board uses three pins and a jumper cap, move the jumper from the
Default position to the Clear position for at least ten seconds. Then,
move the jumper back to the original Default position.

If your board uses two pins without a jumper, place a jumper cap on the
two pins for at least ten seconds, then remove it.

If your board uses solder points, connect both points with a metal object
(the tip of a flathead screwdriver or a paper clip, for example) for at
least ten seconds, then remove the metal object.

4: Re-install the CMOS battery.

5: Plug the system back in, then power it on.

Your BIOS should revert to its original default settings, including
features such as boot order and CPU speed. Press the [Delete] key to
enter your BIOS Setup and configure the BIOS options to your liking.
