Hi. Autorun doesn't work and I've tried several solutions (in control panel or registry) I found online and none of them worked. There's no problem installing software. I also wrote to a CD-R and a DVD-R without errors. The computer is about 10 months old and autorun hasn't worked in a long time so after failing to find a solution, I decided to try a forum. I'm using Windows 7 64-bit, in my opinion, the best OS MS has ever made. Thanks for any suggestions.
