A BIOS checksum error can be caused by a nearly flat BIOS battery.
I would replace the BIOS battery first before attempting to upgrading the BIOS.
Some motherboard BIOS firmware is upgraded by running a program that has been copy to a DOS boot disk or the upgrage maybe done from within the BIOS setup. These firmware upgrage and instructions are on the motherboard WEB site, in your case the Compaq/HP WEB site. Make sure you select the upgrade for your model motherboard.
NOTE it is possible that if you make a mistake you could ruin your motherboard, if you are not sure seek help from a computer savy friend.

SOURCE: Ref GA-81PE1000L Error message on boot up

all the computer bios settings are stored even when the computer is off (like time and fsb)

these are stored due to the help of a cmos battery

when this battery finishes it gives the CMOS Checksum error Default loaded error

all you need to do is replace the cmos cell

it is a mercury cell (looks like a silver coin) and will be placed on your motherboard

it is very very cheap so go buy one and replace it and be happy

Testimonial: "Many thanks for such a quick and effective answer "

If you have reset the CMOS memory you need to go into the BIOS setup screen and reconfigure the BIOS. To do that you need to press a key while the computer is booting. Usually F2 but can be other keys. It should tell you on the bottom of the first screen which key to press to enter BIOS setup.
If you don't know the settings the should be one for optimal defaults - use that one. You will also need to reset the time and date.
Save, Exit and re-boot and everything should then work.
During the boot process you will see on the screen to press delete to enter setup
