Dual Monitors problems ater updating SiSandra and GPU drivers

I recently updated my nVidia drivers to the latest and also my SiSandra Lite software (for quick access to accurate specs of my PC). After updating SiSandra Lite, I looked at the GPU section. As usual it loaded the primary monitor first where everything was fine. I then changed to look at my secondary and my primary monitor turned off and my desktop was shifted to my second.

Now when I boot my computer, my primary comes on, but after the pre and post bios. Only when Grub comes on does something appear on my primary monitor, but it's very low resolution (compared to what it used to be). The windows 7 loading bar appears on my primary but before the logo can appear and glow, it swaps to my secondary monitor where it stays.

Windows 7 cannot detect my primary monitor trying both screen resolution detection and it's missing from the devices menu. Really confused about this whole business

I realise this may have been posted as a problem before. I did find little snippets of information about it but nothing sufficient.

Any help or redirecting to places where this problem has been solved would be much appreciated :)

Thanks

Anyone?

I have now also tried 2 system restores before both the install and GPU driver update and still the problem persists. Strangely enough when I boot into safe mode, it displays on my primary monitor but only at 800x600 resolution, which I cannot change. Only 1 useless reply from SiSandra Lite company and no reply yet from ASUS (GPU manufacturer).

I have found a solution but would still like some advice.

I tracked the problem down (after a week of searching) to a faulty DVI port on my monitor. Using the VGA port allows Windows 7 to 'see' the monitor and use it at full resolution. I have tried changing the DVI cable, changing the graphics card and even changing the computer, the DVI port is the problem. The problem however started whilst observing my monitor setup using SiSandra =S

My new question is this: Is there anything I can do to get the DVI port on my monitor working again or am I doomed to use it's VGA port forever more?

Thanks
