Last night I was playing Fifa then it paused and there was an error message in a little box which I glanced at and think it said something about graphics (should have taken more notice). I closed the box and Fifa disappeared so I tried to reload it but nothing happened. I rebooted the system (Windows 10) which got to the little blue window screen after the spinning dots, then the monitor switched off as if nothing was plugged in. Rebooted and the same happened. I booted into safe mode which strangely had no network connection and was empty when I went to look at network connection details. I uninstalled then reinstalled graphics but the same boot process happened. I loaded Trueimage and recovered a backup but the same happened again, so I have no idea what the issue is and whether its a graphics issue or motherboard. The card is Nvidia Geforce GT 670. Can anyone suggest please?
