Gigabyte Radeon HD 7950 windoforce

>Pic related. What do, Jow Forums??
The lines are fixed, they do not scroll with the image.
They also appear exactly as this in the post/bios.
They also appear when I use another video connection (DVI, mini DP), another cable AND another monitor and are always the same.
I've already disassembled the whole PC, cleaned it entirely INCLUDING the videocard.
>I've also already tried to bake it in the oven on 200ºC (392°F) for 10 minutes and it didn't change anything.
Help me please!! I love this board!

Wait a sec!!
Can you guys see the horizontal red lines on my pic?? I can't know if they're from the pic or from my bugged videocard only...

Also, windows won't start with the proper driver installed. But without the driver installed it works normally. (But with the damned red lines)
