I have Windows 7 Ultimate 64-bit installed and am having problems accessing the Services Panel from the Administrative tools option. The problem is that the Services Panel is showing a blank screen when the default Extended option is selected.
I am unable to figure out the problem that whether it is related to the installation of windows 7 or any file goes corrupt which I am not aware of.

Any ideas are welcome as I am unable to find where the problem is, and hope to avoid having to format and reinstall the system.
