I have been able to burns CD's up until just recently. I used to get the problem fairly often but I would just restart my computer and make sure that I didn't run any other programs before trying to write. Now, however it has stop writting altogether. Any ideas of what is causing my problem. I did a defrag just last week and I've deleted all the temp and recycle bin files as well as run regclean in order to get my computer up to optimal performance but nothing seems to work. Any suggestions?
