Just starting within the past week, CDs and DVDs no longer autorun or autoplay. CDs with autorun.inf don't do anything. Windows doesn't even pop up the "what do you want to do with this CD" box where you have all the choices, like "view files with explorer" and whatnot. There are only two things that I have done that might have caused this. First, I installed The Sims 2 (for my sister). I couldn't even get it to run because I kept getting "DVD/CD-ROM emulation software detected. Please disable..." blah blah, so I got with technical support. They said I needed the Intel Application Accelerator. Yeah, whatever, I downloaded that, it didn't fix it, go figure. Then I read that Intel Application Accelerator isn't even compatible with my chipset, so I do a system restore. I also uninstalled The Sims 2. I looked in TweakUI and noticed that "Enable Autoplay for CD and DVD Drives" was unchecked, so I checked it then restarted. It still is not working. This really isn't that big of a deal, but I'd just like to have it fixed.
