Hey, need some help with my laptop. I bought it in January of 2011 and still carry a warranty until January 2014. It has begun to slow down and I am wondering if I can get it sent in to get cleaned up and sped up under the warranty. I defragment my hard drive and clean the disk almost weekly and also make sure I don't have alot of programs running in the background. What else can I do?

Thanks,

David
