Hey all

So one day I was going through my device manager and I activated my intel graphics (my main is and 280x) and then used the computer for a bit more the I shut it down. I wake up to turn on my computer and I boot into windows 8.1 and then the screen is just black after the windows logo nothing appears nothing at all.Also there is no cursor just pitch black

What I have tried
1.I have tried all the options on repair disk like automatic repair system restore
2. I activated the f8 key so I can try repair mode and I did boot into the menu but the safe mode also has a black screen
3.I have went into my bios and rested my settings to default
4.tried connecting my hdmi cable into my motherboard but the screen doesn't show anything at all
Please help me so far it's been going on for 3 days
