Computer is running slowly. done all the std virus, spy ware, adware checks and run CC Cleaner. I am wondering if more RAM might be useful.

Computer is a emachince upgraded to nearly a gig of RAM. it uses DIMM and is running Windows XT
Additional symptom is that when playing videos, the sound is "clipped" short interruptions about 2 or 3 times a second--even when the video is fully loaded.
