OK. Is this checksum error message is being given by the BIOS (likely) or is this a Windows error message?
If a BIOS message it means the CHECKSUM, a code generated by the BIOS that represents the hardware on the motherboard, does not match the hardware that is detected on boot. And we know why that is.
If your exact CPU is not listed as compatible with the motherboard with the initial BIOS version then you will need to update your BIOS to the most recent version - provided your exact CPU is supported by the motherboard at all - as the other folks have mentioned.
If your exact CPU is
supported by your motherboard with the initial BIOS version then you just need to do a CLEAR CMOS or a CLRTC on the board to update the checksum.
This is not the same thing
as RESTORE BIOS DEFAULTS.
Normally the procedure is this:
- Note all your current BIOS settings
- Shut down the computer > remove the power cord.
- Remove the 3.3v battery.
- Move the CLRTC jumper from pins 1-2 to 2-3.
- Touch a metal part of the case and Press and Hold the reset button on your case for approx. 30 seconds to discharge all power from the board.
- Put the CLRTC jumper back on pins 1-2.
- Replace the 3.3v battery > replace the power cord > boot.
- Immediately go back into BIOS and reset all your preferred settings. If the CLRTC worked you will need to reset the date and time.
Some of the newer motherboards have a CLEAR CMOS button on them to do this instead of the jumper pin. Read your Manual!
