Monitor is going to sleep with new graphics card, why?
Hello, I have a problem with my "new" graphics card. When I start my computer with my old card which is a HD 4670 1G everything works just fine. But when i plug in my new card a Xfx HD 5750 1G i only see the motherboard logo etc. Before windows launches the screen goes black and the monitor is going to sleep. First of all i have tried the card in a different system and it worked fine. I have tried a different monitor - same problem. I've also uninstalled the old video drivers ofc. Any ideas? My system; Mobo: Gigabyte H67MA-D2H-B3 PSU: CORSAIR TX 750 WATT 8G DDR3 RAM
