Try using it for awhile. Our test beds were 512MB and a 1.0GB RAM machine which ran fine. Since no gaming I'd wonder if 7 just needs to finish its indexing and for all the drivers, updates to finish downloading, installing.
Give it a week and then add RAM but don't expect much improvement.
I have installed Windows 7 Pro 32 Bit on my old HP Pavillon 523n I can see I need to upgrade my memory currently 1Gig it will take 2 also my display card needs an upgrade I don't want to spend a lot just enough to run programs no gaming any suggestions. Any info would be greatly appreciated.
Thanks in advance Bido
