Proplems with starting DELL D600



I have got my daughter a DELL D600 it was working fine yesterday but now will only start and stays on the blue DELL page
Can you hit the Enter BIOS key to get into the BIOS? If you can, does it see any hard-drives? Any error messages, odd noises from the drive (outside of the normal spinning and fans).

Laptop is from 2005, could have just died, bad motherboard, bad ram, bad cpu.
