So I was having a problem which I made in an earlier post, but because this is a new error I stupidly made I decided to make a new thread.
My PC was using my intel integrated 4000 HD graphics instead of my Sapphire HD 7970 and was therefore running Skyrim at about 10fps. I was recommended to try disabling Intel graphics in device manager, but upon doing this my monitor just went to power saving mode and will now show nothing. Abosolutely nothing. Other people go into safe mode to fix this but I can't.. Any suggestions?
What Stupido says is true. The only way you could have had that happen if you connected your monitor to the motherboard instead of the graphics card. Connect it to the graphics card and your problems will go away.
if the monitor is coming on then going off just after the windows logo then use F8 just after the splash screen to open the boot menu. you can do 1 of 2 things there. boot into safe mode. windows should load up as normal without disabling the onboard gfx. if it doesnt then use last good config to restor the session where the gfx was working.
disabling the cpugpu in bios and setting the gfx card as the primary gfx in bios should also turn your screen back on.
you may have to set the priority to peg 1 mode to select the pci-e slot that the gfx card is in.
and as sunius points out connect to the gfx card not the motherboards gfx output.
