The thing about the micheal myers books is that it is very, generalized, especially when he talks of beeps, does her MSI motherboard have the D-LED readout bracket? That can be very helpful in diagnosing the motherboard.
Anyways, according to MSI's website, which they use this beepcode layout for almost all the motherboards that they manufacture.
"1 long, 3 short Conventional/Extended memory failure"
Here is the MSI site that I got the information, needed that once before for my self as all my motherboards have been MSI.
MSI Computer Corp. - Support
Just remember, it could be RAM, or her memory controller, or any combo of the two, though, I don't see why it would be wiping out her BIOS.....
EDIT: Here is another site which lists a large majority of possible beep codes and there respective BIOS type, being Award/AMI/NEC/Pheonix.
