As to that LED staying on, take a look at this link. You'll probably skip to #2:

http://support.turtl...tp/63546915.asp

I know with floopy drives when the light stays on it's because the cable is on backwards. Look for bent pins. I've seen it a couple of times.

I would try blowing out the inside of that drive with compressed air. Move the nozzle around and do it thoroughly (sp?). I've seen it work a couple of times. Compressed air is a good thing to have around. You'll use it on other stuff also....like printers, tire valves that lost their cap etc.

As far as re-seating the cable. Sometimes corrosion will build up on a pin and cause something not to work. Re-seating the cable removes or breaks down the invisible corrosion.

the PC works fine if i don't insert any CD/DVD. I asked my dad about this, he said something like "if the cd/dvd drive is working fine if you don't touch it at all, it's probably when you press down a key or move the mouse, it sends an interrupt to CPU and stops the process of the cd drive reading, when the interrupt finishes, the cpu is lost in what it's doing because that interrupt is not suppose to have any effect due to the processing speed (not noticable)" it sounds reasonable that my cd drive isn't exactly broken, but i'll look into the hardware aspects because my case is half open at all times due to a minor problem i had with the heat sink.

I would take a look at device manager. Your looking for yellow exclamation marks and I think the other is a red circle with a line through it. If you see that, you've got a problem.

start>settings>control panel>system>hardware>device manager


I would un-install all of the optical drives in device manager and re-install one of the drives as a master on the secondary cable and see if it locks up. This problem drive is not on the same cable as the hardrive is it?

Boot the pc into safe mode and try using the drive. Press F8 every second or so as you boot the pc up. Then select safe mode from the menu......

Your list makes it seem like you have 2 optical drives. Is there two ? If there is, do both drives cause lockups ?

If your system has only one drive, maybe the lens needs to be cleaned.
----------------------------------------------

Inability to read & write any discs is due, most of the time, to one of two causes: A dirty lens in the optics of the drive, or, a bad drive. Dust and dirt can easily make its way into the drive; that includes smoke, too.

Feeling handy ? Cleaning the lens will cost you no money, but requires you to open the computer's case, extract the optical drive, open the cover to the drive and then gently cleaning the tiny lens with a soft cloth or tissue and rubbing alcohol. As far as all tools that you'll need, use a Philips screwdriver.

If you don't feel reasonably comfortable doing this yourself, is there someone you know who could help you with this ? The whole process should take less than a half an hour. This is the kind of thing I love to do - get my hands on the hardware - I bet one of your friends would help you out if you asked. Be reasonably sure he or she is reasonably competent, though.

I'll run through the disassembly-cleaning-reassembly procedure in a moment, but if you decide to simply replace the drive there are top-notch drives for under $50 delivered to your door (USA). (I'm a big fan both of Neweeg.com and NEC optical drives.)

Whether the computer is a laptop or a desktop you really should try cleaning the lens first before giving up on the optical drive and replacing it. If you don't feel comfortable about partially disassembling your machine then take it to a local repair shop for them to do this. They shouldn't charge more than $25 or so to do this. If they want more than this then get estimates from other outfits.

Cleaning the lens of an optical drive is actually a straight-forward task that should not be too difficult for anyone that knows how to use a screwdriver.

Laptop drive extraction: Most laptop optical drives slide out from the body of the computer by pushing on an exterior eject button on or by the face of the drive. Its a bit tricky to push this eject button and pull on the drive but you should be able to do this fairly easily. These drives are made to slide out.

Desktop computer procedure: You'll need to open the computer case, remove the drive, open up the drive cover and clean the lens. This routine is only slightly more complicated than replacing the drive with a new one.

-) Turn off the computer and pull out the power cord. Note how all the other cables hook up to the back of the computer so you can replace them when you are finishing up the job (monitor cable, speaker cable, network cable or phone cord, USB device wires)

-) Get the now-cable-free computer box up on a table where you can easily work with it.

-) Remove the left side case panel. If it is a non-OEM computer then opening the left side panel will be very easy. There usually will be either 2 Philips head screws or 2 thumbscrews on the back edge of the left side panel that need to be removed. Remove the screws and then slide the panel toward the rear about a half an inch. You should hear a 'clunk' sound and the panel will be able to be lifted away from the case. Set it aside for now.

If your computer is an OEM Dell, HP, Compaq, Gateway, E-Machines, etc., then opening up the case can be somewhat more difficult. If the case doesn't have 2 screws on the back edge of the case then look for a button on the lower left side of the front of the case. When a case has this cover removal button push it in and pull firmly upward or backward on the left side panel to remove it. If the case doesn't have a panel unlocking button the try sliding it towards the rear of the case. OEM computer manufacturers have used all sorts of weird mechanisms to attach the left side case cover. Some Dells use a clamshell design that pivots the left cover away from the rest of the case. There may be a sliding latch on the rear panel of the case that allows you to put a padlock there to prevent anyone from opening the case. Slide this latch out of its closed position in order to allow the panel to be opened.

I have come across OEM cases that I couldn't figure out how to open. You may have to contact the computer manufacturer to get instructions on how to open it. Opening the case may void your warranty, but it looks like this needs to be done nonetheless.

Once the case is opened remove the power cable and carefully wiggle and pull on the ribbon cable attached the back of the optical drive. There will be either 4 screws or a slide latching mechanism that keeps the drive in place in its holder rack. Remove the screws or push on the latching mechanism's release button and slide the drive out the front of the case.

Opening the laptop or desktop drive cover: In either case there will be 3 or 4 screws on the top panel of the optical drive. Unscrew them and carefully remove the sheet metal panel. I find the mechanism of an optical drive to be fascinating. You will see the lens which appears as a glassy bubble in the middle of the exposed mechanism. Wet your soft cloth or tissue with a little rubbing alcohol. Do not apply so much that it drips. Gently wipe the lens in circular motions to clean the lens. You may not actually notice any dust or dirt come off the lens onto the cloth, but this will clean it.

Now, reassemble the optical drive. You know where its screws are, right ?! Replace the optical drive into its bay. Reattach the ribbon cable and then its power cord. Reattach the case side panel and screw any of its attachment screws back in. Return the computer to its original position. Plug back in each of the cables that you pulled out. Note that the speaker wire plugs into a 1/8 inch socket that is usually colored green - there are usually several 1/8 inch sockets of various colors on the sound card panel. If there are USB cables to plug back in then it shouldn't matter which USB sockets they go into. Finally, plug the power cord back in. Before you start up the computer have a fire extinguisher at hand. Just kidding!

Start up your computer and see if the optical drive works now. If it doesn't work properly or at all then you may need to replace it. Now that you know how to take out the drive, replacing it really is easy. Finding a replacement for a laptop drive might be somewhat more of a challenge.

I hope this procedure doesn't appear to be too daunting. Like I mentioned, take it to a repair shop if it sounds too involved for you or you and a friend to do.

The other drive named "PP3388Z JPV945V SCSI CdRom Device" is probably virtual drive. He has an Lg GSA-4163b which is a DVD writer. losted try holding the Shift key while you are inserting the CD/DVD and release it only after the drives led stops flashing. can you access the CD/DVD after that or your PC lock up before the drives LED stops flashing

Back from work.

Thanks for that cleaning lens lesson, even though I don't think the problem is that.

I have held down the shift key while inserting a DVD, and now it seems to be working fine. I am only copying stuff from the DVD to my computer, so what does holding the shift key do?
I am unsure if the problem is solved because it really happens randomly for some reason, but there is a pattern to it.

I am now copying some stuff from another DVD. This time I didn't hold down the shift key. (still would like to know what the shift key does). Gonna be trying stuff here and there to see if there is any further problems.

Edit:
It seems to work fine right now.
Thanks for all your help, I will ask for help again if anything happens.
So, what does hold shift while inserting cd/dvd do?

It disables the autorun. So probably the autorun file on the CD/DVD was damaged and was locking your PC. was there a problem with one particular CD/DVD or particular type of CD/DVD like Video or Data CD?

OMG, yes that's the problem... the autorun DVD I had was a video DVD made in China since it was recording the stuff happened in a reunion of my father's university mates. It is weird formated I think. The autorun did have problem while inserting it. Is there a way to disable? or fix the autorun right now?
