I have just built a new PC, initially everything was ok on first start up but there seemed to be an intermittent fault as I thought it was going into sleep mode but there was still audio running. Then after restarting I would see the bios screen but no output via the HDMI, occasionally it would come back on but then eventually no output at all. I have put back in the GeForce 210 and connected it via the VGA with no problems although I do seem to be getting the same issue via HDMI with the GeForce 210 GPU.
