Dell Vostro 3700 GPU Driver Problem

Hey guys,

I really need help...

I have this Dell Vostro 3700 laptop - with Windows 7 Ultimate x64 installed.

I can not seem to get any of the GPU drivers installed correctly.

I've updated the bios to A12, the newest provided by Dell for this model.

I've even flashed the bios after with custom bios by Doze who supposedly has provided a fix for this model's hybrid GPU issue.

But I am still stuck.

I know it is not Doze's custom bio flash because even before flashing the bios, all of this still remained an issue. So even after bios flash, still no improvement.

Every time I install the GPU - Nvidia Geforce GT 330M - I get this rainbow colored blank screen upon Windows log in.

Everything is ok up until after the Window load screen. Boot bios etc are all fine.

Safe mode works fine and as long as the GPU driver is not installed, microsoft's generic VGA driver works fine too by default although the screen brightness is at 0% and I can not adjust it.

I've updated the driver to the latest version - still no use.

Is the GPU toast or is this some sort of a bug?
