Ocassionsal Video and Audio Stutter
I've recently purchased a new PC (stats to the left) and it's giving me some problems when playing video and games. It's a stutter and is usually rather random. I can play WoW just fine and experience a slight server stutter when performing some data fetching tasks, which I have experienced across 3 PCs to date. For example, a search of the Auction House database, which causes the game graphics to stutter.
I get something similar when playing Team fortress two. If I switch from TF2 (played over the internet to say, firefox for example, and then switch back, I get a loop whilst the game updates to what has been going on since I switched. For example, The audio "three minutes remaining" may go "Thr-e-e-e-e-e-e minutes remaining".
Now, I find this permissible, but it seems to be happening when I play video from my HDD and randomly in TF2. Seemingly at random whilst watching a movie, it'll occur. I can't put my finger on it as it'll happen whilst I'm doing anything - or even nothing other than watching the film itself. So, for example earlier "bad" turned into "b-a-a-a-a-a-a-d". The video acts accordingly.
I've run benchmarks and tests on the CPU, GPU and RAM, and all have a 100% success rate. My codecs and drivers are all up to date.
Does anyone have any idea of what can cause this?
