So the issue I'm having is that i built this as a new rig and installed windows 8.1 on the HyperX Predator PCIe SSD at first when i tired to turn on the system to start the windows install i wasn't receiving video output from my GPU so i figured i take out the GPU and see if that works happily it did. So i installed windows and went from there, I reinstalled My GPU and then it booted and there was video on my monitor so i was happy i proceeded to install windows updates and when that was finished it told me to restart my computer of course so i did and then i started having problems with GPU video output again it wouldn't show anything on screen and it would just say "NO Signal" on my monitor. So again i took my GPU out and ran it on Integrated Graphics i saw video on my monitor this time. I then went into the Bios to make sure my integrated graphics settings were set to PEG which they are. So Finally i installed the GPU again and as it booted its showed a blinking cursor at the top left corner of the screen and then it went into windows. If i try to turn off or restart my PC from here my monitor just shows the "NO SIGNAL" screen again.
Please Any help would be so appreciated i just want to enjoy my new rig thank so much for any support that you can give me.
