Do you know what make the dvd unit is?

Is it a dvdrom only - or a burner too?

How old is it?

Is this a problem only with cdr - or cdrw too; and with all makes?

Have you tried cleaning it - using a dvd/cd lens cleaning kit; essentially a cd/dvd with a few brushes et on it... They can be bought for a few ££/$$$ most places -and of course eBay etc...

I seem to recall reading "somewhere" that cd/dvd units have two laser diodes - at least...; possibly one of these has failed in your unit?

Equally the laser(s) may have become misaligned... and that's not a road down which I would seek to travel in terms of resetting it... Replacement cd/dvd units are usually quite cheap these days. And one can of course use an external unit too - via a usb port?

And some serious reading all about the various systems:

I never saw an optical drive that wouldn't read CDs. Your combo unit has two lasers in it. One for each type (different wave length). So, if the drive is being properly identified by the BIOS in the POST screens I would say your CD laser has burned out. Time for a new drive.

After checking your specs I am pretty sure your CD laser is just worn out. That unit is pretty old. I consider optical drives disposable hardware. Below is one good source for hardware. The link goes directly to combo burners. Your specs, also linked below indicate a SATA II hard drive but do not say what interface the optical drive is. You will need to have a look in the case before buying. IDE has a wide flat ribbon type data cable. Look at the hard drive data cable to see what it looks like. If your optical drive has the same type of cable as your hard drive then you have a SATA type. Even if you currently have an IDE type you could still install a SATA type IF you have the required connections on the motherboard. The power cable may be different too, but an adapter will take care of that.
