I have a DELL Dimension 8300 running Windows XP Pro. I had my hard-drive cleaned up after I realized that there was stuff on it that shouldn't be there. After that, several functions have stopped working correctly. I have found a solution for one of them, but the others still give me trouble. The problems are: -"Drive not accessable. Incorrect function" in the CD drives (solved...somewhat) -iTunes is unable to burn discs correctly -iPod does not re-sync with iTunes to add/remove songs -One user on the computer is unable to run installation programs, or any program labeled "Setup.exe" I first solved the CD Drive problem by openning Windows Media Player when a disc is inserted. This discovery was completely accedental, because I watched a movie on the computer using W.M.P., and was able to see what was on the disc using Windows Explorer after openning the program. Now, I had just recently discovered that activating Disc Detector also works. Does anyone know what's going on?
