Dual boot: WinXP Pro + Win7 Ultimate
 
 

Hi Lemur,
Thank you for your reply.
The complete set of specifications of my system is listed in my profile.
And now to the details of my current problem: My win7 ultimate system behaves strangely. When I do some typing, the screen shutters. When I type, the active window is replace by another one without any clear rationale, when I type, only part of the text gets typed, etc.
I ran an analysis by TuneUp Utilities 2012 and got the following hint:

Windows reports that the "NVIDIA PORT IO Control Driver" device is not working properly.

All I found of NVIDIA products on my task list is a display driver for NVIDIA 9500 GT, which functions with no fault.

What's wrong?
