Problem with NVIDIA Ge Force Go 7900 GS

[LT]

Hi all
Ever since I did a Windows update back in July, my video card has been
acting up. While I'm using the computer the image on the screen starts
breaking up, then I get a black screen. I have to force the computer for a
shut down. After so many re starts I get a message saying " Display Driver
Stopped working and has recovered.
I can use the computer for a little while, and then I get the same problem
again. I took my computer to fix when I started experiencing this problem.
All they did was clean the fan they said the video cards was good.

I have a Toshiba Satellite P105-S9339 bought in June 2007
Windows Vista Ultimate SP2
4 GB Ram 32 bit
Internet Explorer 7
I know a few people here had the same problem. Did someone found the fix for
it?
TIA
LT

It sounds like the video chip is overheating. Try cleaning out the vents.

Have you got the latest drivers from you video card manufacturers Web site
to replace the possibly way out of date drivers that came with you windows
update DVD or from Winupdate?

Yes, the computer is over heating. The fan sometimes works and some times it
doesn't. A month ago I took it for service and they cleaned it up. Thanks
for replying to my question

Toshiba´s web site, but still have the same problem

Heat is the great enemy of computer parts and has an advantage in its war
against notebooks.
The cooling schemes for most notebooks are marginal at best and worse when
discrete graphic chips, Nvidia or ATI, are used no matter how much these
improve performance.
As your machine is out of warranty you have nothing to lose by opening it
and cleaning it yourself.
If not too difficult try to see if the heat sink(s) are firmly attached to
the CPU and whatever else they should be in your particular model.
Sadly there are other explanations for your problem besides heat which could
mean that non-replaceable components are circling the drain. Make sure you
have back-ups.

Hi
Thanks for your reply. When I started having this problem I called Toshiba
Support and they told me to take the computer to an Authorized repair shop
so I did, and the tech cleaned the fan in my laptop. Two weeks later I
started having the same problem, black screen with red dots. I connected the
laptop to an external monitor and the same problem showed on there.
In case I have to replace the graphic card, would you suggest any one in
particular? My graphic card is detached from the mother board.
Thanks
