Stutter / Lag When Playing Games And Mouse Cursor

I am having stuttering Issues while playing any game, occasionally my mouse does this laggy thing on the desktop but rarely, but when in game about 5 minutes into it the game starts acting like im having lag spikes, but it does it when playing non online games as well. Mainly Metro 2033 (most noticeable when a bomb goes off) and Counter Strike GO after 5 minutes or so.When I originally had this problem I had used a program called ToolWiz which I would not recommend, it changes way to much and deleted things from windows. In any Case I reformatted my computer hoping it would solve the problem. [code] Have a Hyper 212 on the CPU 4 great case fans. Idles temps are CPU: 29c 39c under load.... GPU 30c 47c under load.I used FRAPS when in CS GO to check FPS and normal I get about 120fps, WHen the glitching stuff started the fps never went below 90fps, so given for changes in enviroment, I would say FPS isnt an issue.All drivers are updated. Going to run Memtest tonight, but doubt that I will see any issues.

Im trying to get Memtest to boot from disc, but cant seem to get it to load at start up, (had similar problem when I installed fresh OS, had to do it inside OS) But was looking through BIOS settings, and saw some things that somehow got changed, switched it back into Ganged mode, and set Voltage on DRAM to 1.55 from 1.51. Didnt have an issue before with it this low but we will see, still trying to figure out how to get that darn memtest disc to load.
