vista startup problem - black screen/no video signal

[Ramsden]

Hi

Hi Guys, I've had some serious bad luck luck and in absolute frustration I'm
turning to you guys and girls for help!

Problem:

Vista loads up and just before the logo screen (when you can hear the vista
jingle) the screen blacks out. In fact i'm pretty sure my monitor simply
loses signal as I can still hear the sound so it seems like Vista continues
to load.

History

Vista has been working fine on this machine till then. I had this problem
previously and I reinstalled Vista. I really don't want to go through that
again, so any help would be much appreciated.

Here is the spec for my machine:

Intel core 2 quad
4 Gig Ram
2 x NVIDIA GT9600 SLI

Someone suggested that his might be a power problem but it isn't. I've used
PSU calcs to work out my power consumption and i'm ok, also the PC loads up
fine in safe mode.

I've looked around and tried a whole number of things but no luck. I'm
willing to try anything except for a reinstall.

If it loads in safe mode its all most certainly driver problem and first
guess would be graphics driver. Go into safe mode and uninstall graphics
driver then try and load windows. Get back and let me know.

Good luck
Norman

Hey Norman, thanks for your help, really appreciate it.

You were right. I uninstalled the nvidia drivers and am now using the
standard VGA graphics driver. I tried to reinstall the nvidia drivers using
windows update (which installed them to version 7.15.11.7474) and the problem
came back again.

So now i'm back to standard VGA drivers.

Does that mean Nvidia drivers are not going to work for me?

It means that either your SLI calculations weren't correct and/or that one
or both of those video cards is going bad.
