Windows 7: Graphic Card Driver Problem

I have just reinstalled Windows 7 x64 which is OK then install Asrock H55 mobo drivers which is OK but when I install Nvidia gts450 drivers and reboot I end up with a black screen or just a screen with no taskbar or shortcuts, any advice please to get it working.
I have also done a Paragon image from a couple of months ago with the same problem that just shows an empty desktop.

There could be a problem with the driver you are installing - or your video card just doesn't like it. You can try installing a previous version (older version) driver to test.

Or your video card may have gone south (died - the slow death). If it works when using the generic drivers that load from Windows but then fails when you load the nVidia drivers it means that the advanced features of the card - like 3d graphics - are failing or have failed.

You can play with the settings for the card in the nVidia Control panel to see if you can get it to work with the driver, or at the very least isolate wherein the problem lies. If you have played with these settings in the past you should try resetting the factory defaults.

Also try re-seating the card, and check that all the contacts are clean and there is no dust in the slot. Re-check the power cord(s) to the card too.

I have gone back to my old monitor with different connections and it works. I have now reconnected my TV/monitor and all is well.
