Bricked GPU

[MyGetthoRig]

hi...
 

I have a bricked HD7870, it all happen when I play GTA V and all of a sudden the screen went black and nothing responded. Then I restart the PC and it wont post, not even to BIOS. There a postcode error and I looked up showed that the motherboard is waiting for signal from VGA. Then I used my GT710 to test whether is it my motherboard or GPU. It booted up to windows normally. 

 

So then I use my GT710 as my primary video output and my HD7870 as my second. GT710 1st slot and HD7870 2nd slot PCIE. It booted up to windows. THE HD7870 WAS DETECTED AT DEVICE MANAGER. I used GPU-Z and it shows partially of the info for the GPU.

 

So I tried flashing the BIOS with all the .rom file I can find on the Internet, including Techpowerup Vga Bios. I flashed all the HD7870 bios at Techpowerup but nothing seems to work. Please help me..

 

PC spec:

MSI-P55-GD80 (LGA1156)

Xeon X3470

16 GB DDR3

HD7870 / GT710

So Windows booted up ?  Flashing the BIOS is going to do nothing for you.  So with the 7870 on slot 1 you get no post, am I correct on this ?  If so try it on another PCIe slot and forget about the G710 for now, if you get black screen no post then the card is botched.

Sorry it means its a dead GPU.  Try the cards one at a time... If you get no post and black screen then the video card has given up.  Try both tho on slot 1 so we know for sure which video card is broken basically.
