I've had my PC for maybe 2 weeks and everything was fine u til recently. What happens is, when playing a game, for example, Metro 2033, the screen twitches and jitters like crazy when when moving my mouse. It's like the frames freeze and then skip. Heres a short video of it happening 2 or 3 times.
This happens all the time now despite playing at consistently high FPS.
I have a GTX 560 TI and a Phenom 2 x4. I'm playing at max settings in 720p and don't go below 30 fps. I usually am around 50 to 70
I have just discovered that this only happens in DX10 and 11 but not DX9. What doesn't make sense is the fact that I played through 3/4 of the game max settings DX11 with ABSOLUTELY NO PROBLEM. I went through some of the most intense scenes with high frames. Why is it not working anymore?
Edit: I just discovered that the issue no longer exists when recording a clip with fraps. As soon as it stops recording the issue returns. What does this mean?
Looks like you have a microstuttering issue, the framerate is dropping for a very short period of time, too short to register on the framerate counter. You can try running Metro's benchmark, it provides a framerate graph at the end, if you see a lot of extremely brief dips to something like 6 FPS on the graph that is a good indicator that you have this problem.
Is this issue across all games, or restricted to just Metro 2033 in DX10 or 11 mode? Did you update your graphics drivers recently? If you have you can try rolling back to an older version or reinstalling the current version, most of the time microstuttering is due to driver problems. You can also force vsync in the nvidia control panel. Metro doesn't have a vsync option for some reason, but enabling it may help stabilize your framerate.
Have you tried running the benchmark with your network adapter disabled? I've seen rigs exhibit this kind of behaviour when they have picked up some nasty bit of malware or such like and if it was working OK before and has just started doing this out of the blue...
Uninstalled the drivers and installed the new ones and it's still happening...
Edit: Something interesting just happened. After trying to start up the Civ5 and having it one again lock up, I restarted the computer and tried to open a web page, and it said "Cache read error". I then refreshed and it was fine but does that mean anything?

But I'm guessing its not the problem here. But still, do check
