I have a 4-year old desktop with the Windows XP OS (he). The CPU is a Intel, Celeron, 256 MB of Ram. 1.20 ghz, 1200 mhz It is running smooth now, and I want to keep it that way. is there anything that I can do to keep it operating well? The startup seems a little slow, but I have been keeping it on hibernate after 2 hours of non-use I run these programs weekly: Lavasoft Adware, 2007, Avast Anti-virus, Ccleaner, Spybot S&D, Windows Defender, WinPatrol. I use the Mozilla Firefox 18.104.22.168 browser. You all helped me get my laptop running smooth a few months ago, and I want to keep the desktop in good shape. Thanks for all the help.
