For a four year old computer, not really much can be done other then maxing the memory (it lists 8GB as the max) and if there is TWO slots for Hard Drives, add a SSD and reinstall Windows to the SSD with the HDD as storage of files. That will give a nice boost in both but your stuck with a Mobility Radeon HD 5650 Shared memory Video, which is a problem. Have you made sure your on all the latest drivers?
