Off the top of my head it sounds like a communication error.
Start with removing and re connecting the 25 pin cable between the CPU and the d8b. If that doesn't change anything....
Check the BIOS to ensure it is set correctly. If that doesn't change anything.....
Open her up and re-set all the ribbon cables cleaning them with a good cleaner (change the battery while you in there and re-check the BIOS).
Post back.
Sorry it took so long to respond.
Cheers
