Akshay, I quick-formatted and reinstalled windows and I continued to face a bit of framing and mouse-freeze issues ingame... it has nothing to do with partitioning.
Again, installing games on a different hard drive worked for me - I don't know if it will work for you, BUT, I recommend a fresh windows install to eliminate any software/driver related issues. If the reinstalled *does not* work, then try to get hold of a second hard drive from a friend to verify whether your current HDD is the culprit.
