HELP!! My computer is almost 4 years old and it is slower than a dead turtle trying to go uphill in a blizzard. Is there any way I can speed this relic up any? I've installed, and run, System Mechanic (version 6). It really hasn't help all that much. If this thing has to do more than one thing at a time it takes forever and a day. Are there any web-based, or maybe even freeware, programs that can give this thing a swift kick in the rear? Any and all information provided will be appreciated. Thanks!!
