Hi folks;
You guys fixed my Pewter last year and it's worked fine ever since.

I don't think I'm Infected, but I've noticed the 'load' time on my browser and other applications is a tad slow. Not totally freezing up, but it will take several 'extra' mouse clicks to get a site to come up.

Several questions: I understand that Reg Cleaners are unnecessary. But I read about DeFraging the Registry? Is that a necessary service?
Could My mouse be defective?
How about the browser itself. I've used Firefox for the past 5 years, obtaining the latest versions when they come out. When I noticed the decrease in speed, I downloaded 'Google Chrome'. It's fast, but I still get that annoying Quadruple Click action
A buddy of mine says 'It's time to wipe the box clean and start over with a fresh Hard drive'. Says he does it annually. Is that a valid option? My Box hasn't been wiped clean in 6 or 7 years.

Windows XP Media Center Edition Service Pack 3 (build 2600)
2.20 gigahertz AMD Athlon 64 Processor, 160.04 GB Hard drive, Memory:Slot 'A0' has 512 MB, Slot 'A1' has 256 MB.

Any thoughts?
