It's a fresh install of XP with all updates, Symantic AV, Spybot S&D run regularly. Had the same type of problems before reinstalling Windows, so it must be some kind of hardware problem. My sister's iPod worked fine when she first installed it, but then iTunes stopped recognizing it (windows does see it though). I thought the problem might be that Windows was upgraded from a messy Windows ME factory installation to Windows XP, so I did a format and install. The iPod still didn't work though. Dial-up (Earthlink) worked fine untill a few days ago when it would act as if it were connected, but couldn't load anything. Now the Earthlink dialer says that there is a missing file when you try to connect. The whole time (before and after the Windows reinstall) the computer ran much slower than it should, especially when it came to starting programs. This lead me to believe that maybe the HD had bad spots which might cause data loss and performance issues. I bought a USB 2.0 pci card (it only had onboard 1.1) to install hoping it would help the iPod problem. If anyone can think of what might be causing this I'd love to know. The computer is a HP Pavillion XE793 with a 700Mhz Celeron, 192MB ram, and a 30GB HD.
Thanks
