I have a P3 Demension XPS T600mhz w/128 megs RAM. It had been running pretty well, but soon I realized it was running ungodly slow! I used the msconfig to take out all the uneeded programs running in the background. I used some Registry cleaner to try to wipe out some of the registry, looked like it took forever, probably had a lot of excess waste in the registry. I SCANDISK, I Defragged, BUT ITS STILL SLOW!!!! WHY???????? I can't figure this out. It is really slow, takes a few seconds to even open up a sub menu when you right click on an icon on the desktop, this computer might as well be a 486! please help...
