Firstly,,yes XP is now loaded up,,Second ,,,yes full security programs can make your system crawl,,and adding more RAM might prob. help..,,,,then "Also Limit what starts when the OS is loaded. That has a direct affect on the resources used and therefore the speed. Good luck. ",,,,,here is the meat of my answer,,there is no info. on how to do that,,,go to START,,go to SEARCH,,go to ALL FILES AND FOLDERS,,type in MSCONFIG in both slots,,with the search slot being drive C,,,pick "msconfig.exe" from the search list by double clicking it.,,System Configuration window opens up so now pick the STARTUP button,,,,now uncheck all the start up programs that you guess that you just plain ol don't need at start up,,,that you can run from the desk top button or from the program files.Hit apply.,,restart..and see if this helps ...as far as the aformentioned start up stuff is concerned..there are other things that could be messed up,,like malware & virus stuff,,,down load and run Malwarebytes from CNET downloads.,,,and get rid of your TEMPORARY INTERNET FILES,,which someone else can explain,,,Clingtotree
