MY computer isn't finding my Nec 3500

I have a Compaq presario sr1109uk and have recently bought a nec 3500 dvdr, although after having connected the dvdr to the expansion bay port, each time I boot the system it doesn’t get past the Bios start up. If i unconnect the drive it boots no problem, windows finds the drive but won’t finish it’s installation until it reboots, which as I said doesn’t happen when the drive is connected.

I did get a warning about the system wasn’t starting because it was protetcing my files due to new hardware being dedicted.

I tried entering the bios setup but don’t have much experience in there.

I order the 3500 of the net and didn’t get any software with it.

Can anyone help me out?
