Have you tried cleaning out your laptop? It might be bogged down with a lot of unnecessary crapware, trialware and such. I would try one of two things.... download Microsoft Security Essentials (it's free and in my opinion on of the better anti-virus products out there, and also visit: www.shouldiremoveit.com (another free option) and do a program search for Asus (this will give you info about they types of programs installed and will help you to determine which items to uninstall in order to free up some space)
Also, stay away from registry cleaners... as they really don't offer that much relief... if any.
Hope this helps!
Thank you I will try
