ok im having a kind of weird problem here. any audio/video is fine on my computer when nothing else is running, but when anything else is running it starts skipping around and some what slows down the song or video im watching. its really weird, I dont think its my cpu because my cpu is rather new is an AMD Athlon 64 X2 Dual-core 4600+ overclocked to 2.72 ghz. im pretty sure its not my ram, I have 4 gigs of ddr2. im not sure what else could be causing it. any ideas?
