Thanks for the advice and tips, will certainly bear them in mind. I seem to have solved the problem, did a search on Google and located another forum with people with identical faults, all related to the CD/RW. I deleted the CD/RW from my computer, then rebooted it, tried to burn the disc and the blue screen of death re-appeared. Tried another alternative, searched and located the latest drivers for my CD/RW and downloaded them followed by a reboot. Now it is burning and copying discs without any worries. Thanks for any help and advice SDHMAN
