Hi,

The checksum error probably means that your CMOS, has recently been reset, or there is some invalid setting. However, if you're unable to even access your BIOS (by pressing F1 or F2 or DEL or whatever), then you might have a problem with your keyboard. Have you tried using a different keyboard? Are you pressing the F1 key right away, or not until you get this error?

With any checksum error, the first thing I would do is replace the cmos battery on the motherboard.

You can also try using the jumpers on the motherboard to reset it, or just removing the battery for a few minutes.

Beyond that, overclocking, corrupt BIOS (requiring a BIOS flash) and sometimes unstable processors can all be potential causes.

What is your BIOS type (Award, Phoenix, other...)?

Personally I haven't seen this particular checksum message addressed before, you might want to review some of these links which cover it:
