I did have a CD-rom problem...the thning was...that I have first..of all, another CRAP cd-rom installed in the computer.. how now Idea why it is so... but this was so for my...becuase I have a crap CD-rom....and have crap IDE cable for harddriver and for the crap CD-rom.... the perfect new CD-RW didn't work for 100%... so you might change IDE-cables and look for you CD-rom....if it's works batter...or mount with Alcohol tools...
