Would it help to eliminate the virtual memory and close the page file completely?
I am having the same problems mentioned here but to the extreme, with a Dell 8250 running Vista. In the past month or so I have increased the RAM from something around 612mb to 2GB. I have increased the on board video memory from almost nothing to 512mb. I have run every single test or repair available where ever I could find it. Everything says my system is in ultra-excellent shape. Yet, I still have to wait forever for a page to load, to be able to use the mouse on a new page, to be able to to do almost anything. The truth is, I am about to virtually pull my virtual hair out.
I will try your suggestions but I think I need an Extreme Makeover for this thing. Can I just reload Vista again right on top of the present one? It was an upgrade to begin with. Would that help?
