7870 intermittent no signal

[venm1]

What I tried so far : disabling onboard ( then I had to use the cmos jumper because I had no display on both the dedicated and onboard ), changing the pci-e cables, reformatted, reseated, but sometimes I don't see anything when I plug it into the gpu.

The card ( when it is recognized ) works fine, I played bioshock infinite in ultra pretty smoothly, but I hate the fact that I never know if it's going to be recognized or not which is why I came here hoping to get some help/advice on what I should do.


According to siw the card is disabled ( when it doesnt display ) and in eventviewer I see a couple of red exclamation marks with atieclxx.exe as a faulty module when there is no signal. Also I see a direct correlation when the gpu's fan start at full speed ( loud ) there is no signal, when it's quiet it works (however if the card is quiet at boot it'll stay quiet for the rest of the time I left the pc on).


I have 8 days left to rma it unless I find a way to fix it.
