Reason for showing "check main

your bios has been damaged the bios chip on your motherboard could be damaged to check it

restart your compuetr during the boot up process you will see a certain key to press to enter set up (bios) press and hold that key to enter bios using the arrow keys scroll to load optimised defaults

You will also need to reset the time and date.

In the main or system setup screen you should be able to see the date and time Using your arrow keys navigate to the date and change the date.

Once highlighted on the month, day, or year, press your arrow keys or your page up / page down keys to change the date.
Save, Exit and re-boot and everything should then work.

Mainboard GA-G31-ES2C Warning: Backup BIOS checksum error BIOS Auto-Recovering...

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

Mainboard GA-G31-ES2C Warning: Backup BIOS checksum error BIOS Auto-Recovering...

try to find a copy of the bios from the manufacture's website, and put it on a usb stick, then start the computer with the usb stick plugged in. if that doesn't work, you may have to replace the bios chip with a properly programmed one. if you can replace it, then you would have to replace your motherboard (unless I missing something here on how to recover the bios)

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

Checksum error

Hi Oliver, the most common error related to the message,
(Bios Rom Checksum Error). Someone has left a floppy disk in the floppy drive. Once the floppy disk has been removed press the reset button on the PC, your windows will start normally. Next place to look is in your bios.
Open your manual to page 27.
Enter your bios & go to the title Advanced BIOS Features. Check First, Second & Third boot devices they should be as follows. Floppy disk drive, CD-ROM drive & primary hard disk drive. If both of the above are ok than try clearing the cmos/bios by resetting the cmos jumper (JP1) location on page 5. Descriptions of page five on page 6. CMOS settings on page 9.
When your system restarts re-enter your cmos & reset up your bios settings. Lastly if none of the above has fixed the error message, than remove the cmos battery & check its voltage. It should maintain 3volts. If yours' is lower than 3volts replace the cmos battery. There is one other possible fix. It’s an option not given lightly. Flashing a cmos/bios is not recommended unless all other options have failed.

Good luck Oliver!
