I have a Compac aramarda 7770DMT and what happened with the Bios is this, from normal operation on one day,on the next day on power up the bios failed to complete it's checks, so I switched it off and back on again and every time (the computer was powered up) the bios failed to complete it's checks, it checked less items as shown on the screen untill there was nothing being checked at all and finally on hitting the power switch nothing at all would happen, not even a twitch from the power supply. I'm sure if I could get another bios It would work again, unfortunately I don't have a spare to do a hot swap.
It looked like every time it was powered up the BIOS lost a bit more ground untill total failure to even start the power supply. The old beastie is scrap yard special if the bios can not be fixed as a new mother board is worth as much as a new computer.
Any Ideas please people ???? because I'm all out
