    Monitor Loses Signal When Windows Boots Up


    When I start my computer with drivers installed my monitor loses the signal when I should be receiving a log in screen. I can boot up fine in safemode and/or if I'm using Standard VGA Graphics Adapter. To my knowledge I do not have an onboard graphics card as there is nothing to plug an avi or vga cord into aside from my graphics card. I should also mention I tried using an NVIDIA GeForce 8500 GT and experienced the same problem.
    I am running 64 bit windows 7 and my graphics card is an NVIDIA GTX 560.

    Boot into safemode and delete the nvidia drivers, then boot normally and install fresh drivers. Not 100% sure it'll work, but it's worth a shot.

    Boot into Safemode w/ networking (it will use a standard VGA driver from Microsoft instead of the nvidia) and if it still works the driver is the problem so download the latest drivers for your Geforce GTX 560 which is this: Drivers | GeForce . If it does not display when on Safemode then its hardware problems (either Monitor or the Video card itself, but im not sure on this)

    This happened before with another PC of mine. Hope that helps! Feel free to reply back if the problem still occurs =)

    tried, clean installing windows and then clean installing 5 different versions of the drivers, nothing works, and it happens with 2 different graphics. I've contacted the company i purchased my pc form and am sending it back for them to take a look at.

    What kind of cable are you using to connect the monitor to the pc?

    Are you using 2 output devices on your video card?
