White sceen when in full sceen on the net.

Did you install the proper drivers for your video card?

i went to the Nvidia site this site under download drivers told me i needed 'forceware release 90 Ver 93.71 whql and directed me to the down load page, i downloaded it and installed it, when my pc restarted all the icons on my desktop were huge so i went to properties - setting- advanced to change it and got a message 'coud not install controll panel likely reason missmatched driver' or words to that effect, i just dont know whats happening as when this card was in another pc it worked fine (with Nvidia controll pannel) i even found the driver cd that came with the card and manual, so i installed it from the cd first i tried doing it by going to device manager and choosing update driver telling it were to look and a general search and a message came back saying 'could not find a better driver that i had already had installed' or words to that effect, so i followed the manuals steps, but still no luck, i noticed in the manual it saying something about the monitor used, saying if it is not branded i might not get all the options my monitor is a 'syncmaster 750s' i didnt install any drivers for this as it worked when i plugged it into my pc, could this have anything to do with it. im grasping at straws here, blooming (like to use a stronger word here) P.Cs they got a life of their own.

First uninstall the drivers you downloaded and use the ones provided on the CD as these should be compatible. Next you may have to ensure that the computer is attached to your TV prior to turning on your computer. Some of the older cards have a hard time detecting TVs. If your still having problems getting it to work on the TV then you can use NVidia control panel (if reinstalling the drivers gets it to install properly) and select force TV detection. This will allow you to output a signal to the TV reguardless of it being plugged in or not. Try these options out and tell us how it goes.
