I've recently tried to install my new graphic card. its an ASUS R9270-DC2OC-2GD5 Radeon R9 270 2GB 256-bit GDDR5 PCI Express 3.0 HDCP Ready CrossFireX Support Video Card. This isn't a new build I was just upgrading my hardware.My base system is a h8-1210, I also have recently installed a 500 watt psu. My old gpu was working with ease with this psu.So I believe nothing else is broken like my mobo,cpu etc.
I hear windows booting in the background as well. I've tried every port on it,as well as tv & monitors. Is this a DOA issue? I also notice there is a green led lit up on the gpu also. Am I completely missing something??
Thanks
