Hey guys, I have had my computer for a while now and it has not done this until this morning. Last night, I left my computer to defrag over the night and shut off when done. I turn it on, let things load, launch Skyrim, and all of a sudden I see my mouse stuttering. It moves in a jerky motion, not smoothly like it did before. Can someone help me fix this? I have been researching non stop and cannot find a solution!
