Hi all, I have a Geforce 6600gt 128mb which i have had for about 5 months now and all of a sudden today, my computer screen freezes and shuts off. Now everytime i boot my computer, it gets to windows loading screen with the moving bar and then after that the compute goes black and after 5 seconds goes to standby but the computer is still running. I tried going into safe mode and reinstalling the drivers for my video card from both the website and my driver cd but when i go to install the drivers, it goes black agian and then into standby again. please does anyone know why this is and how to fix it? thanks.
