9260 with bands of video noise

I have a 9260 with the GeForce Go 7950 GTX video card.
Recently I've been experiencing display problems when watching Hulu (Flash Video I believe).
I get horizontal bands of "noise" while watching video.
I've removed, cleaned, and Arctic Silvered the video card heatsink. It started again shortly afterwards. I've also re-installed the stock video drivers.
Has anyone else experienced these issues?

Plug in an external monitor. If it is fine then your LCD is failing.

cheers ...

I'll try that. It doesn't do it all the time. Like right now, it's fine.

Intermittent on an external, constant on the internal LCD - correct?

I am still optimistic that it is only the LCD and not the GPU. Try updating codecs and flash again.

cheers ...

Intermittent on the internal LCD. I haven't tried an external yet. Sorry of my previous post was misleading.
If it is the GPU, can't I just get a new one?

This has been fixed. It turns out it was a Windows XP problem. I tried several different driver versions and even re-installed XP. At some point it downloads an update that starts the problem.
I got fed up with it happening and installed Win 7 x64 and haven't had the problem since.

Love Aero with a decent video card.

A great idea on threads like this is either the OP or a MOD writes a conclusion? In addition to the obvious it will offer a better Google search. Maybe just me but I am sick of putting in the keyword and the first link is to the question. It happens way too much.

Gonna be tough for a simple conclusion pp. In this case the OS upgrade works for OP on a not so new system. Many times it is the other way around, mainly staying put with what you got.

But hopefully a search on "video noise" would bring users here.

cheers ...

OK. The problem is back.
I've tried the original Sager drivers (156.76) as well as the newest found on the nvidia site (179.48) and the ones that can be downloaded via windows update (179.67).
I think it's a windows update problem. For a while My Windows 7 x64 install was running fine. No problems at all. The just days ago, it cropped up again.
It doesn't do it all the time. It seems to happen with some web pages in both IE and Firefox that have black areas. But it will happen across the whole screen.
I'll keep looking.
I may try ntune to mess with clock speeds if possible.

Bummer. Did you just have an update from Microsoft? Try to go back to the restore point?

I'm not sure. It's been a few days. I've installed ntune and found the clock settings at 575MHz for core bus and 700MHz for memory. I clocked it back to 575 and 602. We'll see what happens. If it doesn't happen for a while, I'll set them back and wait to see if there's any relationship between clock speed and the noise.

I wonder if the 280M would drop in to my machine.

I just thought I'd post an update.
AFter mu switch to 602 MHz on 2/22/2010 I haven't had any video noise.
Of course having written that, It will probably crop up again.
