Problems with AMD HD 7990

Right so,

I've been having problems with an HD 7790 recently, an XFX Radeon HD 7990 to be exact.

One of the essentially two 7770's in the card refuses to work/enable whatever I try.

To be exact I don't know if the side enabling is working, as there is no video out from the card.

I got the card working once, after repeating the same task for hours, It worked correctly and ran games as it should.

Once I had rebooted my pc and turned it back on though, it went back to how it was before and till this day.

I've tried the following:

  • Tearing down the card, checking if anything on the card itself seems to be broken (Removing dust, applying new thermal paste, etc)
  • Flashing the cards vBios
  • Use of DDU to remove any remaining display driver

I've attached some images of what Windows shows me, as well as the apparent issue.

If I could get some assistance on this issue, I'd appreciate it.

I've already tried this,

The screen goes black for like 20-30 seconds then switches back to integrated graphics.

Thanks for the reply
