I recently have been having a problem with my computer and was hoping someone might know of a solution. I have a dell desktop with a 2.8 GHz Intel processor 1 gig RAM, an 80 gig primary drive, a 200gig internal secondary drive, and 2 250gig external drives attached via USB cable. Approx 5 weeks ago, all of a sudden whenever the comp starts to run slow with too many processes, the desktop appearance goes from XP style to classis style and back again, but now my sound doesn't work...it removes the device(SoundBlaster 5.1 card) from the list of hardware devices completely and only the modem device is listed. A reboot fixes the problem, but it is a big hassle to reboot all the time. One example is I will open a media player, then try to search for a file from within...this causes the appearance to change and then no sound, so I have to reboot to have sound on the file I was trying to open. I have used MSconfig and startup manager to only startup what I think are essential files, and have not changed anything that I know of when the problem started. Any ideas?
