Okay, so last night I took out my CPU and GPU, then after fiddling around (cleaning) I place them back. The thing is that now everything seems to be a lot jagged (kinda laggy), for example, I can useually run minecraft 60FPS no problem, but now it seems to vary from 30-50.

I'm not sure if I'm just being paranoid or not..

Anyway specs are:

I3 2120
8GB 1333MHz
Sapphire Radeon HD 7770


ALSO, sometimes a game will randomly freeze and get really laggy, and the fps will drop, but they will go back up after 2 seconds.
 
Solution
You should check your CPU/GPU temperatures to see if they're running too hot. When you took out the CPU, did you remove the old thermal paste and apply new paste properly?
