my sons machine appears to go into power saving mode after boot up. ( no graphics )I have tried his graphics card in my PC with no problem. his PC starts in safe mode ok !! and have run a system restore, but to no avail, Help !!!!!!
re-installed graphics card and booted up ok,but screen was at lowest resolution, each time i attempt to increase resolution i lose the picture. also if i leave resolution low and restart im back to square one !!!
