Hello all. I've been struggling with a video card my brother gave me and could use some help please.
Processor: Intel
Memory: 16GB DDR3
GPU: Gigabyte Radeon HD 6870OC-Gd
OS: Windows 10 64bit
So he told me that it had stopped working(I'm assuming he overclocked it without knowing what he was doing or something stupid) and I decided to take a crack at it. Here are the symptoms:
1) Two green broken vertical lines on POST and in Windows
2) Upon entering windows in normal mode, the GPU quickly overheats and all I get is a black screen but the fans are still running.
3) Booting into safe mode the GPU never overheats and there is far less artifacting.
4) I have tried using atiflash to flash gigbayte's rom onto the GPU through DOS. This worked but the artifacts remained.
5) I have taken apart the GPU, cleaned it thoroughly and applied new thermal paste.
6) Both AMD's and Gigabyte's software installers spit out errors and cannot install drivers.
7) GPU-Z cannot detect the card
8) Windows does not display anything except "Microsoft basic display adapter"
9) I cannot seem to install the drivers for the card through AMD or Gigabyte.
10) The GPU "works" though and when the HDMI is plugged in, I get an image but with the two vertical lines as mentioned.
So where do I go from here? My last resort/thought is to try the good old fashioned "Throw it in the oven" trick, but I'm thinking at worst it's a memory issue(Game over) or at best a bad flash/overclock he did and if I can try something else?
Thanks for all input.
