Right after changing mb from pegatron gl8 to as rock h61m dgs everytime I try to install my gtx 750 ti oc I get black screen now picture at all I have an upgraded psu so I doubt that's the issue I just tried to install drivers off the cd that came with it it says cannot continue as can't find compatible drivers but I know that this motherboard is compatible with this mb as I looked at another thread on here and a few people say it does and I got told to get this mb as it would be sufficient any advice would be appreciated
