I have XP Pro sp2. I opened the task manager to see if I could see why my computer is running so slow. I added up all the RAM listed and it's no where near the gig of RAM I have, but my performance meter is constantly at 100% and all I have open are my internet security (Trend Micro Systems) and 4 IE7 windows. I have defragged, uninstalled programs I wasn't using, still I can't do anything. Little history: I had Norton Internet Security 2006. This is when I noticed that I couldn't open hardly anything without locking up my pc. Called their tech support, they tell me its memory leakage....call the manufacturer. Manufacturer says Norton is fulla crap, so I deleted it got a different one. But I'm still having the problem. Anyone have any suggestions?
