I'm doing an upgrade on a computer with a new: PSU/Mobo/RAM/CPU but I get this error upon start up. I've verified that the IDE cables are plugged in correctly and I've tried all the jumper settings on the hard drive but no devices show up in the BIOS. I've set the boot order as CD/DVD, Floppy, Hard drive. I've tried two sets of IDE cables but to no avail. Any other solutions to this problem?
