I have an HP Desktop w/ AMD 3800+ CPU, 3 Gb of RAM, running an Asus EN8600 Silent Video card, on XP.
I have noticed that when I click an application, it take about a second or two for the machine to respond, and it use to not do that. I've looked at my system info, and the ram is there, and everything reports that it is working properly, but it seems quirky at times. Also, Firefox is now putting up ads on my windows and that has never happened.
Any ideas??
