I just installed the Vista Service Pack 1 update. Everything looked fine until my screen suddenly went black - it behaves just like when i turn off my computer but leaves the screen on. I waited a good three hours and pushed the reset button. Then computer restarted and the screen worked fine until the Vista icon was about to show up - it then went black again. Tried a hard restart, pressing my power button for 10 secs. I could hear it restart, but my screen never got any signals. The screen cords are all plugged in as normal. I have tested a bit and this is what happens:

- Restart by reset button: Screen is getting signals and working fine until windows startup sound, then it goes offline.
- Restart by pressing power button: Screen is totaly offline.
- Starting windows in safety mode works fine. Tried to update drivers, but they were up to date.

This is my computer (tabletop):

What should I do? I hope it's not dead...

Try to boot to Safe Mode and uninstall it under Programs and Features.

I see you reckon you have the drivers up to date. However, I would consider obtaining the latest graphics drivers from the home site, uninstalling completly your present ones, reboot and reinstall your new drivers. You could also try disabling your anti virus during the operation.

Thanks for the help, but it seems I need another solution. I uninstalled SP 1 and the screen would not work as it should (same problem as before). I then uninstalled my Geforce drivers, and the screen worked fine (although the graphics were not very good) even in normal windows mode. I then installed the latest driver from Nvidia website, and now the screen is offline again.

Any ideas?

It does seem like a graphic driver problem then. Possibly SP1 or Vista is, in fact, installing the latest driver, which unfortunately is the same one you are trying to install.
I browsed around the Nvidia links (Sorry - running blind on this one, I use ATI) and found that it was a question of incompatibility with Intel chipsets. Nvidia are "working on it"??
But installing this driver seems to have had some succes, but not for everyone:

The driver from the link you provided could not be installed as windows did not find any components that could use that driver. Anyway, I uninstalled the previous driver, rebooted and windows installed a driver automatically. And now it works! So it seems like the problem is between SP1 and my graphic card driver, so I recon I should not install SP1 before this issue has been solved by Nvidia/Intel. Can you please post the link to where I can find info on this?

Thanks for all the help!

It was in a discussion on the Forums. You can start browsing here, I think

More and more I am finding the solution to be the older and safer Omega drivers for both ATi and Nvidia:
