your slowing down because of A) your memeory or B) your processor...my guess would be that it is a memory problem...try defragging the system and see if that helps...there is a program that is good for defragging your memory too...
memturbo 2 ...it is a 30 day trial...oh and if you don't like things being left on your system then try this uninstaller...
your uninstaller ...it's a trial too 21 days but if you like it you can purchase it...boy I hope I'm not going overboard with all these applications Sabrina...
