Can you upgrade your computer instead of buying a new one? We just upgraded my son's computer and its like brand new.

A hardware upgrade can be simple depending on the usage and workload the computer has to deal with. For instance if your computer as an AMD Athlon X4 860K and you plan to do video production and editing you would need to upgrade to an i7 or a XEON processor which depending on your region can be very expensive.

Small things like a graphics card upgrade or additional RAM is very simple. Going from an HDD to an SSD can make a big difference as well in terms of boot time and other programs that benefit from using an SSD.

Programs like Hitmanpro, CCcleaner, and antimalware can track down cookies that could potentially be slowing down the performance of your hardware.

Malwarebytes anyone?

Malwarebytes is fantastic.
