Just installed new mobo to replace old one that died. Swapping in one exactly the same but computer won't detect keyboard so I can't get into bios. This is the reason I decided to update BIOS. Followed the directions on Intel website for updating BIOS both with flash drive and cd. Neither worked. Version of BIOS is 431, tried to update to 444 then 478. MoBo is an INTEL D915GAG socket 775. When attempting to update comp just hangs cpu fan is on but the monitor light just blinks off and on. Tried to enter setup by putting jumper on pins 2 and 3 which is labeled 'config' then upon start-up message 'entering setup...' appears at bottom of screen but it just hangs there.
