use ccleaner to clean registry and c:. that may help a bit. Also, uninstall any unwanted/unused softwares.

[Psychosocial]

De-frag your HDD
And as desii said, use CCleaner to clean you registery.

Also scan your laptop for any viruses and open task manager and close unwanted processes before gaming.
