Next run a defrag,a good one found HERE
Choose a hard drive from an easy-to-read pull-down menu, and Disk Defrag instantly displays the drive's size, and used and free space. The program even displays a pie graph for visual learners. One click starts the defragmentation process. The program's defrag process screen displays another handy visual. A sector map makes it easy to see how much of the drive is fragmented, allocated, or free. As the program churns away, the defragged sectors are displayed in blue.
Next download and run ccleaner ccleaner
Open the program select tools then select startup and disable all programs except your antivirus.Anything else you can click on to use the only thing you really nee starting up is your anti virus.Hope this info helps out and if I were you I would defintly install some more ram It is simple See Image Here
And also would like to mention that ccleaner has a registry cleaner option I would just stay away from that part of the program. Although ccleaner is a usefull tool, registry cleaners are no good unless you know what you are deleting.
