I recently had problems with my dvd drive so i went in my computer and fiddled AROUND with the IDE cables with my dvd drive and the hdd. I unplugged them from the motherboard and i think i tried switching the cables. I returned the cables to the  ir normal places but now when i turn the computer on, the monitor just says check signal. Also, the beep that usually occurs when i turn it on does not happen. Is there any WAY i can FIX this?Monkeying around inside a case is not a good idea unless you know what you are doing.

That being said, put the hard drive on IDE primary channel and the optical drives on the secondary IDE channel. Start the MACHINE and go into BIOS/setup and see if they are recognized.

If it doesn't work think carefully. What else did you PLAY with?
 

the hard drive is on the primary and the dvd drive is on the secondary but it still does not work.
the two IDE cables the connect the hard drive and the dvd drive to the motherboard are all that i messed around with
the monitor does not get a signal from the computer, but i dont think there is anything wrong with the monitor so could there be something wrong with the motherboard?Did you swap PATA flat ribbon cables when the PC was powered on?

If not; are you certain that the red stripe is aligned with pin one?
