It happens, just go to 'my computer', then find the drive and double click, it will then start up. It can get annoying but windows is lame so what do you expect?

To to My Computer, right click, go to Hardware, Device Manager and see if you really have a DVD/CD ROM drive.  My guess is you only have a CD drive, which will neither play nor burn DVDs.\n-MM

Make sure you don't have any other programs running whilst you are burning.  If that dosen't help then take a look at the bargain cd drives you can buy on ebay.

Re-boot and go into the Bios and see if they are being recognized there.  If not, try a different power connector from the power supply. It sounds like the drives aren't even getting power. It's hard to believe both drives could go bad at once.  Even if the IDE Controller went bad, the drive tray will still open as long as it's getting power.

It can be a couple of things.\n\nLikely culprits?:\n1. the cooling fan.  Check for buildup on the rear fan, use canned air to clean.\n\n2. The Processor fan. Look on the motherboard and watch the little cooling fan. Clean with canned air or replace.\n\n3. A warped CD in the cdrom drive. When PCs start they spin the drive. make sure it's empty.\n\n4. A heavily fragmented hard drive. If the drive is fairly full the drive has to look all over the place for your files. Delete all uneeded files and defrag the drive 2-3 times.\n\nif your PC is losing the time, that is due to a bad motherboard battery. If it's under a year old, it should be under warranty.

sometimes they will not start automatically.  have you used your "start" button on the lower left and then clicked on "run"?

unless you've made changes to your system lately (i.e. reformatting, installed new software, etc.) it is probably a hardware failure and needs to be replaced.  You can see what device manger tells you about the status.  Right click on my computer, select manage, select, device manager, browse to your cd drive and see what it says about the device properties.

You could be having a hardware error.  Check the disk you are trying to use in another drive, and try a known good disk in your drive.  Once you verify the problem, then check all the connections on your CD drive, make sure they are solid and the unit is getting power. If everything checks out and it doesnt work, you will have to replace the hardware.

first check led of power of cd-rom is glowing or not.\nif not then check the power supply of drive. \nif it is glowing then check databus of drive and check it's connection in motherboard.\n\nthen it is not working then repair the operating system.

The most likely culprit is a failing CMOS backup battery.  The little coin battery on the motherboard.(rare these days but they also could be regular AA batteries)  The symptom is that it doesn't recognise the drives properly on startup but if you enter BIOS setup and then exit without turning the machine off it will start up.

run scandisk and make sure you check the option to scan the surface area for physical damage.  If your computer seems to be running slower and there is a kind of grinding noise coming from the drive, it's probably time to replace it before losing all of your data.

how many have you made?  Most drives will eventually wear out and stop working.  Maybe your drive isn't working anymore, or maybe its not connected right, or maybe you just need to reinstall the drivers.

better u check for ay virus or else check the connetion of the external wires aswellas internal wire which is the one connecting the CD drive and the  MOB and power supplier with the MOB

Are you sure you have a dvd reader  or just a cd drive???

Have you tried running a Cleaning CD through your drive - it looks like an ordinary CD with a spiral of tiny brushes on it, some have music tracks to make it play for a few seconds, if it hasn't simply inserting it a couple of times will do the trick.

the unit where you start windows has bad sectors, the HDD, or FDD that you're using to start test it with chkdsk.exe starting in safe mode with DOS prompt. Check if your CD has no scratches (if you're talking about start the windows install)
