I went off to college about a week ago, and ever since completing the move, I've been getting horrible performance out of my computer. I was able to play nearly anything at 60fps without any fuss, but now I can barely hold 25fps at a steady rate.
You need to provide system specifications to even hope for a helpful answer.
Given that you've done a physical move, there are two things to check right away:
1) Are all the power connectors secure?
2) What is the room temperature, and if it's high (no A/C), what kind of ventilation do you have in the case?
3) As time as has passed, are you comparing the same games, or new games, which might perform worse simply by virtue of being new and more demanding?
