Graphics drivers issues after reinstall, black stripes and slow redraw

[mgalexray]

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.

after going through so many driver versions it may be wise to completely wipe the current driver (along with whatever pieces remain of the previous ones) then use the latest one provided by amd/ati again.
Here is a tool for that purpose.
Phyxion.net - Driver Sweeper
(you only want to remove display drivers)

Also is the catalyst control center working at all?

Thank you for your response.

I've tried cleaning everything and reinstalling latest drivers, it did not help...

I do have the CCC and it's working fine as far as I can tell, thought there are no settings in there which could help me.

Here's a question, if you take a screenshot, are the black stripes in the screenshot?

 

[mgalexray]

No, they're not. I was puzzled by that as well.

Does anyone have any ideas on where the problem may be?

Hi

I'm not sure if this will help, but looking at your system hardware, some of it have dedicated 512mb video memory and 1024 shared memory.
Here is a blind shot you might try, pull out you memory card, clean it up with dry clothes and reseat it back to memory slot firmly.
If it still does not work, I might guess it has any hardware issue then.

I assume you already reinstall all necessary drivers.
