I'm looking for a bit of advice here. I picked up a case (already had IDE DVD-RW drive installed) and motherboard free, and had a processor and some RAM to fit the board, so thought I'd put it all together. So I connected up an IDE hard drive (which I know works in another machine) and started the machine up. The LED light at the front comes on, and the CPU fan rotates, so power is coming into the machine. However, no light comes on at the front of the DVD drive, and the hard drive cannot be heard spinning up. Strangely, if I disconnect the ribbon cable from either of these IDE devices, and leave only the 4-pin power cable plugged on, power is getting to them - the hard drive can be heard spinning up, and the DVD drive will open/close. I've tried 2 or 3 different ribbon cables, and also tried only having one of the devices connected instead of the two of them at once, but I still get the same result. It's as if the ribbon cables, when connected, are somehow stopping power getting to the drives.
Another thing I'm getting is that no display of any type is appearing on the monitor, no BIOS screen, nothing! The monitor and VGA cable is working fine on another machine, so I know it's not that...
