You need to reset your CMOS to defaults and this can be achieved in one of two ways. Disconnect power. Open the case. Method 1 Set your CMOS reset jumper in the RESET position and press the start button. Return the jumper to the RUN position then re-connect power. OR Method 2. Remove the CMOS battery for 1 minute. Replace the battery and then re-start.
In either case you will need to go into BIOS and check / adjust your settings.
