Can I Overclock My CPU ?

Laptops are made for portability. You will either need to purchase a laptop suitable for your requirements, live with what you have, or use/purchase a desktop system suitable for your requirements. If you need extreme processing power, speed, large amounts of memory or hard disk storage, or improved graphics, then you will find it much less expensive to fill your requirements with a desktop (purchase or build). If you need the power and the portability also you will be in for a rather large bill for a machine to fill your needs, or you will need to wait a bit longer for your processing.

Try making sure you do not have processes running in the background and do general maintenance (Disk Clean Up, Defrag, antimalware, etc) and that might help a bit.

You have to be a little bit crazy to keep you from going insane.
