as mentioned, big lack of memory! go to
https://www.crucial.com to find exactly what memory you need. download the system memory scanner and run it.
upgrade to the largest amount you computer allows - it's worth it!
i would do another clean install, as well since the "free registry cleaner" may have had a trojan/virus/worm/etc. attached to it or infection may have coincided with the download.
OR
Buy a Mac!
