Video problem no display

[YoshiHDify]

Hello,

I've rebooted my PC and the next thing that happened was beeping followed by no display on my monitor, the rest of the computer clearly kept on booting as if it was a "no vga card installed" situation. 

 

I've done some manual reading for my "INTEL DZ77GA-70K" motherboard and found this out:

-The beep pattern meant "When no VGA option ROM is found"

-Debug LED (Eb) meant "Calling Video BIOS"

 

My GPU is a 7870 hawk which as a distinctive "reverse fan" on boot which is loud, now it doesn't make the sound but the 

leds on the card still light up.

 

I found out what is wrong but I cannot interpret the information above, can someone help me understand what this means?

I mean my PC was working 1 minute and a restart leads to this...

And what if you take the GPU out and then boot it?

Try to reseat the gpu. Make sure all the power connections are snug. Could be a chance that your PSU is pooping out and doesn't have enough to power up your GPU.

Try to boot with integrated graphics. If it shows up on the display, your GPU might have some problems.

but the leds on the card still light up.

wait.the leds stay like that all the time ? or just a sec?if so, that means that the card doesn`t have enough power to run.check the cables.

They stay on the whole time

 

EDIT:

Shutting down my PC for a while, then it boots again with display as if nothing happened. What on earth is going on?
