every time i restart my computer, i must enter setup to change the bios to "user defined", otherwise the bios will say, "not installed" concerning my primary master hard drive. why is it doing this? I just bought this computer and added nic card anddsl modem and more ram. WHY is the bios not recognizing my hard drive unless I set it to user defined? i have to set it to user defined EVERYTIME I restart the computer!

First check that the Bios is latest updated version and can support the drive

Check the IDE cable from the motherboard to hard drive to make sure that it is connected properly,check th pin configuration on the back of the drive,your bios may be conflicting with master slave setting with another device

Make sure that the CMOS backup battery is in good shape, and is making good contact in it's socket.
For the lithium coin-cell type, the battery should measure no less than 3 volts.

Make sure in BIOS settings that NO drives are set for auto-detect.

Make sure that you are hitting the proper SAVE option when you exit BIOS setup.
I would save, then save and exit.

Double-Check the HD's setting jumper to be safe...
It SHOULD be set to Master (from what I'm reading).

It might be set to CS / Cable Select or have fallen off completely....

To be fair, As listed above, I think it's the CMOS battery too.
