Windows Experience Index isn't a good benchmark, don't look at it.
Lag in games is probably caused by your GT 520, which is a low-range GPU. Don't expect high fps in modern games...
Try to lower graphics and maybe set a low resolution... this will increase fps in games.

An hard disk wouldn't slow games so much, but you can try to defrag it.
also try to clean up your pc with programs like CCleaner.
And, as M1GU31 said, try to update drivers
. If you already have 301.42WHQL version, downgrade it. It is currently causing a lot of issues with a lot of games... Maybe this could be the problem.
What resolution are you currently using in desktop and in games?
