try downloading the latest version of ccleaner from filehippo.com.all downloads on this site are free. run this cleaner on a daily basis, and you will see a dramatic difference in the way that your pc responds. it also scans your pc registry for any errors, and gives you the option to fix issues. i have been using this software fo a while now, and have had no trouble at all. pleae let me know if this solved the problem.cheers, Tony.
