I have purchased the new Compaq CQ45-137tx notebook and under that I have windows 7 and windows vista on dual mode. Every time you boot into Windows 7, the cracks start sound and the screen is slow I can see that the cursor (circle) in Windows 7 is rotating slower than normal. Desktop takes a long time to appear and the whole system becomes slow because of this issue. Now I don’t how to solve this issue. Can anyone suggest on this and so that I can solve mine issue.
