Sounds like problem with bios, it may be corrupted, do this, remove the 3vdc button cell battery and leave it out for few minutes, there may be jumper to clear cmos, use it if you know how, other wise leave the battery out for few minutes and than install it back, this will clear date, time etc. and also will clear corrupted tables and other things in cmos, this might just work and after that if you do get the bios menu reset it and it should take the default parameters and detect everything you have. Try this and than post the result, so we can go further.
