I have just upgraded my pc with a new motherboard, celeron processor and Maxtor 6L080L0 80gb hard drive. I also have a Western Digital WD800JB 80gb hard drive from my previous pc setup but when I try to install it and boot up, the computer can't find the primary hard drive (Maxtor) or the secondary drive (WD) even though the jumpers are set correctly. I have also tried booting up with the WD Lifeguard Tools disc in the floppy drive but it says it can't find the hard drive.
I am currently using the IDE cable to connect to the motherboard.
Can anybody give me some ideas on how to rectify this extremely annoying problem?
Many thanks in advance.
