I have a Dell Optiplex GX270 and have recently changed the Motherboard. I did have one CD-RAM drive not working properly but now both drives will not read or write. They both show up in the Control Panel Hardware Devices and are enabled. I can see them both in Windows Explorer but when I insert a CD or DVD they both whirl and then shut down. I have tried changing one to a older but working CD Drive but the same problem exists. One is configured Master and one Slave.

An Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard. Remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

the beeps are post during post the very first work is done by the ram,all the memory in the ram is first transferred to the hard disk,and remains active untill turned off. the grrr is the sound its not getting enough power test your PSU power supply unit or replace it if the fan is not working the PSU is faulty One bad/faulty lead can cause a computer with lots of problems replace all the leads that attach to your hard drive including electrical extensions + IDE,SATAthe ones that attach from your motherboard to hard drive make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty ? hope this helps
First think I would try would be to set bios back to default
Seconed, set all drives to auto in bios
Third remove the cd cable from the motherboard
fourth try drive on cable select
fifth try drive on master
sixth is drive fdisked?
Seventh try drive on another computer.
this is because there is fault in the ram . replace the ram and the problem will be fixed . basically in dell optiplex gx270 when ram do not work the system becomes blank . try to plug out the ram an plug in if system didn't work this time then you have to change the ram
Hmmm--when you went into the BIOS setup, your first boot device should be CD. The next your hard drive. The other boot devices should be set to disabled. Now if you have a third boot device as a network device, then your computer is not seeing the CD or the Hard drive--you have a problem. If all the drives are hooked up properly (sounds like you have that covered) then your motherboard is probably the problem. I would try to disconnect all your stuff except the CD. Try it on the first IDE channel (set it either as cable select or master). If that fails, try it on the other channel. Do you have a second CD to swap out? Still no boot? Bad motherboard.
Drive is more than likely fried. It's not uncommon to have DVD/CDRW drives or any burning drive go bad especially if you use it frequently. Check www.newegg.com for a replacement they shouldn't be more than 30 dollars for a decent model now.
