My comp is about 3 years old and a bit clunky these days. I want to clean it out and make it run nice and stable. Is there a way around this without reformatting it? Some kind of software for cleaning out the registry, startup and overall performance? I guess the ram and CPU are becoming more and more out of date, while the software I continue to upgrade needs more overhead. I use Windows XP (Home) and am aware of software for Macs that are like "conflict cleaners." Anything like this for PC? In the past, reformatting really sped up the programs, but it's such a hassle with all the gigs of crap I'll need to backup.
