Thank you for your help. I looked on Sony's site, and found this: http://esupport.sony.com/US/perl/news-item...amp;news_id=349
In July 2008, NVIDIA announced that some notebook computers with NVIDIA graphic processors manufactured with a certain material set were failing in the field at a higher than normal rate. Since that announcement, Sony, in cooperation with NVIDIA, has been looking into any possible effect to VAIOŽ notebooks with NVIDIA graphic processors. Until recently we had not identified any VAIO models that were affected by this issue.
However, after closely monitoring the situation, Sony has now determined that a very small percentage of VAIO computers with the NVIDIA graphics chips may experience this issue. These PCs may exhibit distorted video, duplicate images or a blank screen due to a failure of the NVIDIA graphics chip.
This issue only applies to the versions of these VAIOŽ computer models that came with a NVIDIAŽ graphics chip:
* VGN-AR1xx, VGN-AR2xx, VGN-AR3xx
* VGN-FZ1xx, VGN-FZ2xx, VGN-FZ3xx, VGN-FZ4xx
* VGC-LT1xx, VGC-LT2xx
As a part of our commitment to quality, for any customer who requires repair of their VAIO computer due to the NVIDIA graphics processor issue, Sony will cover the cost of repair (parts and labor) at no charge and, in addition to the standard limited 12 month warranty, Sony will provide a three year warranty extension for the NVIDIA graphics chip.
