How do you speed up your PC?

The most effective & would speed up your system 100x better... is to disable all the services that you don't use. This can be found in Control Panel/Administrative Tool/Services... But this should be done correctly & you need an aid of a PRO...

I know you mention software, but there is an awesome free program that does this all for you! IOBit.com has a free program that does all this with one push of the blue button, I've been using this for over a year and think you should check it out! tdemex

I do not know how to adjust the virtual memory. But I often defragment my computer from time to time as well as do a disk check on a scheduled basis. I have an application that called the "uninstaller" and it has a certain feature that usually cleans the computer of any unused files. Have also installed registry mechanic that will eventually check the registry for errors from time to time. I am not an expert in computers or programs so basically, that is just what I do.
