hard disk instal. failure

I took my hard disks out of my computer and installed them in a new computer.  When I returned the hard drives to their
original computer, it wouldn't boot up.  When I try to boot
up I hear it access the RAM but nothing shows on the screen.
I also hear it beep a few times.  I tried changing the parallel cables to see if that helped, I also tried only using one hard drive.  Both of my hard drives are not usable
and I don't have access to another computer to see if they still work.  Any ideas?

Probably nothing to do with the hard drives.Pull all hard drive cables at the motherboard or hard drive interface card and see if you at least get video.If not,you probably jostled loose the video card or ram memory.Also possible (but unlikely) is that CMOS got corrupted;clear it with the jumper on the motherboard.
umm.. just simple suggestions. have you detected the harddisks in bios, jumpers on the hdd for slave, master etc.

you say that nothing shows on the screen. the bios should still boot up even though there are no hdd's installed. so if you can't get anything on the screen i think it's either your video card or your monitor that isn't right.

just to mentition: how do you hear the RAM-access?!?!?!?!?!?!?
>I hear it access the RAM
The beeps that you are hearing refer to a device, controller, so on that has failed the power on self test. Go to http://www.pcguide. Select search. Type in BIOS beep codes. Select the one the applies to your system.
