High CPU load while scrolling and moving windows

[Gross, Michael]

Hi,

since last week I'm using Windows Vista Business 32 on my notebook (HP
Compaq nx8220) and I'm wondering about the high CPU utilization while
scrolling in a browser (no matter which one) and moving windows around
the desktop.

In such cases the process itself (like iexplore.exe, when talking about
scrolling) utilizes the CPU 100%, not dwm.exe!

The CPU in my Notbeook is a 1,8GHz Pentium Mobile (Sonoma) while the
GPU is a Mobility Radeon X600 from ATI/AMD. I've installed the latest
drivers from ATI/AMD (from January 29th). It's got 1GB RAM.

The problem occurs as well with Aero as with the other schemes (like
Aero Basic).

Does anyone experience similar behaviours regarding CPU load?

Does HP have Vista drivers for that notebook? You need to install Vista
drivers for all the hardware - motherboard, sound, video, etc. Your post
seems to indicate that you haven't installed Vista drivers.

HP itself does not offer HP drivers for this notebook.

However, except the drivers for my video card all drivers were installed
during the Vista installation / Windows Update and should hence be Vista
drivers, shouldn't they?

The drivers for my video card are Vista drivers directly obtained from
ATI/AMD.

I'll try to replace drivers obtained from Windows Update against original
drivers of the manufacturer now (if possible).
