Graphic problem on FZ31S

[marrodfer]

Hi,

I have a VGN-FZ31S that is getting problems with the graphics about one month. The system stopped working with several glitches and i can get it working perfect.

I have installed Windows Vista and Windows 7 from a clean install. Everything goes right with the generic VGA driver. When i install Sony official for Vistal (with update too) or any i have downloaded from internet i get the same problem. When it boots the system stop or i get a BSOD with this glitches:

Working on Bios, safe mode o any live cd i tryed is ok.

I have call sony support instead of it is not on guarantee and it has been 25 minutes (very expenses). They have told me that as i have not the recovery disks the only thing they can do is to offer me to buy them.

I am sure that the System Windows Vista is the same if i install one and install the driver that if a do a recovery.

I dont remember the concrete date i bought it but it is sure that this system is on the 4 years for GPU problem.

Any one can help me?? what should i do??

Thanks,
