Download "Advanced System Care free" from iobit

Version 5.3 is the latest, or try the 6.1 beta version

Let it run several times in deepcare mode and it does wonders to older or lower end PC's.

I run it on all my systems (7)  to keep them clean.
it was the first app I installed on my i5 quad and my i7 hyperquad also.

You will be surpriced at how much better a clean PC runs.
