I have a Sony Vaio series S 13 laptop with a nVidia 640m LE graphics card recently when using the dedicated grpahics card these tearing, dots and colours are visible making applications unusable.

(The last image is using my integrated card and as you can see the image is smooth).

I have tried removing and installed an older version of the graphics driver etc......what else do I do?

What is wrong?

Thank you for your time

It's not a temperature problem as it happens instantly as the PC boots up even when the GPU is 35 C. I'll try the motherboard drivers....

If you have already tried reverting to an older driver version, and it is still happening, then its probably the hardware itself. You may just have a bad GPU.

The best thing to do is return it.
