Default 820-4924 please help

I got this machine that had been severely messed with but managed to get it to boot. The bios area has been messed with as well, so the bios may not be the original one. When I try and reinstall ios it boots to about 75% and then image vanishes -backlight still on.

The bottom cover and box both have the serial C02P8HSKFVH3 - can someone please look at the uploaded bios for me?

Thank you

Does this mean there's an issue with the board and not the bios?

thanks for the file - similar to the first file, when trying to install ios it gets to about 3/4 then stops, after a minute the image vanishes -backlight stilll on- then after a minute switches off.

Perhaps there is another issue with the board - I'll go over it again
