CDRW/DVD problem, help needed

[Absolution]

I've got a Philips CDD5101 CD-R/RW-DVD Combo Drive on a WinXP machine, and it can't read audio and blank CDs anymore, you can hear the cd spin and the LED will flash but that's it. When i put a DVD, it works perfectly fine. I don't know what the problem is, i've tried different CD-R medias and music CD, but they also don't work. I've also re-installed the drive, and the device manager hasn't picked up anything wrong.
What im trying to do is listen to my audio cds and also burn some programs. But the CDRW/DVD cannot read any CDs anymore except DVDs. The problem first happened last week, when i tried to burn a CD with RecordNow DX, it kept asking to put a cd in when there was one already in. I then tried to access the CDs through 'My computer' but the CDs will just spin and not load up and no info is displayed under the drive.

I got a firmware from the manufacture's website but it didn't solve the problem. tho, the firmware was dated Oct 02', the month I bought the PC.

Can anyone help? Thanks
