So i just bought a new Gigabyte Geforce GTX 660 graphics card to replace my old 9800GT. I installed the card the same way i have installed all other gpu's and turned the computer on to install the drivers that came with the card.
When i rebooted to check if everything had worked the screen went black as soon as the "starting windows" logo had dissapeared. I restarted in safe mode to undo the driver changes so that the computer was again useable. I noticed that by unplugging my second monitor and installing the latest drivers that the main monitor works perfectly. If i try to reboot and plug in the second monitor then the same black screen error happens. So i tried booting with only 1 monitor and then plugging the second in when the computer was running. This simply caused the monitor to not be detected, i checked device manager as well and nothing was shown. To investigate further, i tried to boot with only the 'second' monitor plugged in and found that i did not even get an image for the 'starting windows logo' this time.
From this i gather that there is some clash that causes the second monitor to not allow the first to display when both are plugged in. The primary monitor is connected via a DVI-I cable and the secondary via HDMI. I have tried a separate HDMI cable incase that was the problem but to no avail.
I used both of these monitors with the previous graphics card so I know that they are both in working order.
My current specs are:
Motherboard: Asus M5A78L-M LE
Graphics: Gigabyte GeForce GTX 660
RAM: 4gb Corsair (all i know sorry)
Processor: AMD Phenom II X4 955 Black
OS: Windows 7 Ultimate
Primary Monitor: BenQ G2410HD
Secondary Monitor: BenQ E2220HD
If I havent supplied any required info then I apologize and will try to find it straight away.
