Hi, I was wondering if anyone could help me with a problem, i built a pc about 6 to 8 months ago and everything was running perfectly until about 3 weeks ago, now when if i listen to music or watch a film on the pc the sound and video would stutter approx every 8 seconds, I restarted my pc and everything worked fine for a while but it keeps happening. Is it worth putting a bigger graphics card in (128mb at moment) or should i re load windows. Thanks
