Drives dont work

You're speaking CD drives? Beats me.... I'd guess that the IDE ports on the motherboard, fried; Only thing that would go against that is if the HDD is connected to the same IDE port.

Is your HDD SATA, and the CD drives using IDE? If so, then I stand by my guess.... IDE ports probably died on the motherboard.

I have 2 internal and 1 external drives in my computer that worked fine for years. now when there is a CD in any one of them the computer says the trays are empty. why is it that all 3 drives dont work?M49907

I would try deleting the upper and lower filters in your registry. I had that problem some time ago and that took care of it just fine. However there is also a bug in Nero that used to cause that problem, updating to the latest final release (not beta) could fix it, if not, delete your filters. I beleive the registry key is: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

Start>Run> and type in regedit. Then cntrl F and type in {4D36E965-E325-11CE-BFC1-08002BE10318}. Then you will see a few things. Delete the ones for your CD Rom and DVD Roms. You should always make a back up of your registry before you do anything.

bump

Its my dads computer and he asked me to try to fix that for him I couldent figure it out so here I am again. But because all of the drives are not working, how would i go about making a back up?

Also im not sure if this makes a difference, but none of the USB drives work. The keyboard and mouse are Ps/2 or what ever its called.

If these are two cd/dvd drives, open your computer and check the cable, if you haven't already. Also possible the cable went bad, try a new one. Check the connection, and maybe unplug from the motherboard and put it back in. Same from the connection on the drive itself.
