My DVD ROM, when insert a data disk, sometimes cannot read the disk properly. I know for a fact that the disks work as I've tried it on another computer.

This is what usually happens:
I put the disk in. (Usually a data DVD with videos)
The DVD loads - the disk shows up on My Computer.
I open the DVD drive with the contents of the DVD in it, and it takes a while to load. But sometimes, it stops loading (I think the disk may have stopped turning inside the DVD-ROM because the noise is gone) and my computer goes into this laggy-choppy state where I can't do anything save move my mouse around. The mouse is very choppy on the screen. Unless I eject the disk, this continues and there's no other way around it.

I have no idea if this helps, but I have according to the device manager, the DVD ROM is a
_NEC DVD_RW ND-2540A SCSI CdRom Device with version 5.1.2535.0

Thanks in advanced.

First of all keep in mind that your drive may be failing due to time...In that case you ll have to replace it :(

Then check into what mode your IDE controller is. To easily locate the correct controller in case you have many, get into device manager and select view devices by connection under the view tab. You'll see something like the attached image. Select the controller which is conected to your drive and check under advanced settings in what transfer mode it is set. If the current one is PIO mode then this may be the problem. In that case uninstall the controller from your machine and reboot. Windows will install the controller again and revert back to the correct mode UDMA/DMA.

I've found the transfer mode is set to DMA if available.

Does this mean my drive is aging?

Are you sure that you checked the correct controller? What about the field "current transfer mode"?

On my machine I get Ultra DMA5 in current transfer mode field, on both controllers that are connected with my devices. The other controllers report "not applicable" in the same field. So
if you re not sure that you checked the correct controller please recheck. :)

It is possible that your drive is aging, yes, just to make sure change the cables connecting it to your motherboard in case they are faulty.
