My Samsung SM-352B Combo CDW/DVD does not read CD nor write either

Hello, I have a computer with an Intel Motherboard 850g and a Pentium 4 1.3 Ghz procesor,384 MB of Ram an 2 hard drives. One HP CD Writer Plus 8200 series and a Samsung Combo DVD/CDW SM-352B.The first is the master and the Samsung de slave. I can not write anything in the Samsung and it also can read CD´s. It can read DVD´s only, so I caný use it to burn any CD. The HP works fine but is old and slow. I want to use the Samsung. :sad:
Can any one help me with this problem ?
Thank you in advance
