I'm having an odd PC problem that's just cropped up in the last couple of days, and I don't know the cause (obviously) or the cure.

Ever encounter a problem with your PC where when playing a game, every 30 seconds or so you'd get a major drop in framerates like the computer is locking up, drops to like 5 frames a second, this lasts about 5 seconds then back to normal?

Has nothing to do with intensive screen action either as it'll happen in anything.

Happens in any game at any random moment, but around every 20-30 secs intervals.

Checked the temp levels and they all seem fine.

I'm terribly vexed! <img src="/ubbthreads/images/graemlins/think.gif" alt="" />
