Right first off fell free to move this topic if it is in the wrong section.
Now onto my problem. About 4 weeks ago i expirienced a Memory dump BSOD while running fallout 3. Ever since then games have never been the same. Despite always reporting a very high FPS games always have an extremely annoying sort of stutter/jolting that happens for roughly 1/2 a second every second. I'm lost with what could cause this sort of lag, Espesially since Fraps always reports an Fps of 70+ in games like Fallout 3 and New Vegas.
My Cpu temp is 35 idle. Max 40 under load.
Cpu is overclocked to 3.45Ghz From 2.50. though i'm not sure i've done the overclocking properly
I aslo get lag when Particle effects like dust and steam appear in games. Then my Frames will drop to 20 when i look at said particles. And up to 70 again when i dont look at them.
i have replaced My graphics Card to An ATI 5750 From an Nvidia 9600Gt
I have Replaced my Psu from a genericpieceofs*** 500Watt to an Fsp 600Watt
What resolution are you trying to play at? I wouldn't call the 5750 "high-powered". It's going to struggle a lot with higher details and higher resolutions. I'm going to guess that you're trying to play with too high of settings for the card, especially since the problem happends when there's something that will stress the GPU (like debris and dust).
