what could be wrong?--completely dumbfounded

Not sure whether to post this thread here or in the hardware forum. Need advise.

In trying to optimise and protect my new PC, it seems that my dvdrw is not able to read any of the CDs (be it installation cd or any others). There's still light blinking initially when I put in the CD but it stops pretty soon even though some noise can still be heard. There is nothing on my LCD screen at all to indicate that a CD has been inserted.

I can only think of 2 things that could have potentially cause this besides the DVDRW being spoilt ie ;
I have installed 'tweakui' and disabled 'unplug n pray'. However, even afer uninstalling tweakui (before uninstalling I ensured that the dvdrw drive was not on this) and enabling 'unplug n pray', nothing can be read from my dvdrw. I've even restarted my computer a few times and not successful. Appreciate any advise. I have not installed a lot of things yet from my CD to my HDD thus, really need some help here. Thanks.

 

Did exactly as you said but still can't read the CD.

My steps:
Click on start
Right click computer
Click on Properties
Click on Hardware
Click on Device Manager
Click on DVD/CD-Rom Drives
Click and uninstall HL-DT-ST DVDRAM GSA-H42N SCSI CD-rom device. Restart the computer

Did that a few times. Each time I will see the DVD /cd-rom still there again. Tried installing the CD but still can't work. Please advise. Thanks.
