Maxflyer,
When I asked for the specs, I meant all the hardware. Example which model, Vid Card, CDRW, Mobo, Sound Card, HD, etc. (Otherwise it makes it very hard to picture and research the hardware in your system.)
Have you tried different media? (Before we give up on the CDRW.)
Take Care,
Richard
P.S. If you have another comp, try a test in that comp to make sure. (If it is dead, this would be a great time to get a Dual Layer DVD Burner.)
