Hope someone out there can help me as I have little knowledge with Windows 7 or NVIDIA drivers
. I have a Sony VAIO Model VGN SZ650N that came installed with Vista (32 bit) and I upgraded in January to Windows 7 (32). The PC has NVIDIA GE Force 8400 M GS card. It worked perfectly for over 3 months, then suddenly my screen looks like it's taken a massive dose of LSD! All white areas are now hot pink and there are squiggly lines or dots everywhere. I can get the white areas white again by performing Color Calibration but that doesn't fix the weird lines. And it doesn't stick. I have to re-perform the calibration each time I turn the computer on.
I contacted Sony and paid $150 for a service contract (since mine is out of warranty) and they downloaded new NVIDIA drivers - to no avail. I perused the forum and saw someone else with a similar problem. The suggestion was to modify the NV_DISP.inf file ("Convert from Desktop to Mobile (Laptop); I tried it and it didn't work.
Is this a software issue or is my NVIDIA card going bad? Does anyone know cause Sony (in India) can't figure it out.
