i bought a samsung SH-S182M drive and when i install the dvd drive the computer no longer recognizes that any drives are installed and wont get past the bios. when i unplug ide cable from the drive the computer boots up fine. the specs of the computer are pentium 4 2.0 ghz and motherboard is asus p4s533. i have three other drives installed in the computer right now and i have tried the samsung dvd burner in both ide channels and using different ide cables. does anyone have any idea as to what the problem could be?
