Whenever I try to watch streaming videos online on my dell dimension 2350 my CPU usage would go up to 100%. The video would play like it's in slow motion and the audio would be a few seconds ahead. The weird thing is that my computer doesn't seem to have any problem playing videos that I've downloaded. I know for sure that my internet is not the problem because this is only happening on this one computer. I bought a video card (visiontek 7k 64mb), cpu (Pentium 4 2.4ghz northwood) and added 1 gig of ram but that didn't seem to do anything. Can someone please help me figure out what's wrong with my computer?
