I have a Windows XP computer, and it's been acting up for a while. The internet is slow sometimes, and sometimes it doesn't work at all. Sometimes my sound card uninstalls itself and I have no sound, so I have to reinstall the sound. Also, sometimes the desktop doesn't load completely. Only the wallpaper loads, not the taskbar and start menu. I have to go on Task Manager, click New Task, and type explorer.exe to get the taskbar and icons. I have the Windows XP setup CD right in front of me as I type this. Should I reinstall the operating system? I think ifI do that I won't have those problems anymore.
