Screen redraw problems? Pixelated until pressing 'refresh' key

[Pulsedriver]

Hi folks;

Not for my PC but a friend is having a problem;

Windows Vista launches, and there are visible pixels/artifacts on screen, at first I thought it'd be the onboard display card faulty, however it isn't, as rather than artifacts, the pixels increase if you move a window etc

So say for example you were viewing a webpage, each time you move down, the text becomes unreadable eventually the whole thing pixellates until you press refresh...
It does it in windows, if you grab a window and move it around, eventually the screen fills up! (Seems like a redraw issue?)

Im sure it's a problem with hardware acceleration, as when he had XP the same thing happened then he turned it off, and it worked fine.

But with Vista, the option is greyed out, and in safe mode it will not write the changes to the registry.

Is there any solution? Or do they have to get a cheap standalone graphics card to solve it?

PS, the motherboard is MSI AM2 with Nforce 6150 onboard (latest drivers).

No ideas?

I would try a diff OS to rule out compatability issues first. Install a spare hard drive if you have one and try XP. If problems persist then it's pretty much got to be faulty hardware in which case he maybe able to return the motherboard.

A simple fix would be to just buy a new vid card. Onboard display adapters suck anyway.

Edit - you could try and turn off all the gimicky features to the OS too, not sure if this is an option on Vista personally as I haven't used it yet!

With XP it did it, until I turned off hardware acceleration to 'none' and it was fine.

In Vista it's different, there is no option for it, only in safe mode, and even then it doesnt let you apply the change.

Guessing a cheap graphics card will solve their issue

Thanks
