Handling Grief Like Old Motherboard

Events that are very irritating and annoying that occurred on the device I'm  know how I should handle it. Some days I long to get a job to fix the customer's computer type VGA Motherboard Asus P4B226 with 16MB of memory is 256 MB.Initially I was very excited in the affairs of a computer repair ... so booting direct flame and the message, which means there is roughly a sharp system or collide ... know that I restart dn go into safe mode and of course with a little warming in order to because the situation was so bad I try to update the bios with the latest version .. with software built first ... asus bios had a little success and went up I think it was from 2000 up to 2002 .. .. but it felt relieved that my name thrilled with the new things and dissatisfaction finally updated my bios again with the newer version again ... happens ERROR and after boot / restart the computer to stay alive but the monitor does not show anything black aka ... now live remorse because of dissatisfaction. now the customer's computer still can not be resolved. Should I replace the board? or memory or something I have not found the road?
