Nvidia 3100M Quadro full screen video problems

I had this discussion to some degree without resolution in the E6510 owner's lounge.

Summary: I bought a refurb FHD i7-720QM E6510 which has the following issue:

YouTube - Nvidia NVS Quadro 3100M full screen flickering issue

I tried reinstalling everything, all version of drivers, including betas, 32 bit OS installs, 64 bit OS installs all kinds of browsers and flash installation in chrome etc.

Nothing worked.

After a bit they sent E6410 which worked but I didn't want a 6410.

So they finally sent a NEW 6510 yesterday and that has the same issue!

Can someone please help me understand if there's something I'm overlooking or I'm just jinxed?

Thanks.

 

I have installed every driver NVidia has released in the past two months, the ones listed on Dell's website, both 32 bit and 64 bit (while on that respective OS version 32/64).
