Graphics drivers issues after reinstall, black stripes and slow redraw
Hi Everyone,
Recently I decided to finally reinstall my W7, since it was ~2yrs old and getting slower each day. I used the official MSDN W7 Professional ISO SP1 and did a clean install.
Unfortunately, I've been having this problem which I can't solve no matter what. It seems to me that there's some graphics issues - When resizing any window, it takes some tome while it redraws it's contents, you can actually see it updating the contents. Also, it leaves nasty black areas/stripes when I do that, similar to this:

Also, there's some sort of flickering involved as well.
Machine in question is: HP ProBook 4515s With AMD/ATi HD 4330, running W7 32bit SP1
I have tried the following, without success:
- the default drivers on the HP website
- the drivers provided by windows update service
- latest mobile drivers from AMD
- modded drivers with Mobility Modder
- Aero On / Aero Off / Disabling every visual effect
- Updating BIOS
- Doing the same on x64 version of windows.
I have DirectX updated, and all other patches and drivers should be there as well.
I'm hitting the brick wall here, so I'm out of ideas. I'd be gratefull if someone could shine some light on this. :)
Thanks.
