Problem with Aurora R4 Graphics Card AMD Radeon HD 6870 1GB

I've been searching around for answers on this and I'm stumped

I usually let my computer go to sleep and just let it run, I don't shut it down very often. Recently it began not displaying anything when I would wake it up my display would just say no signal. So a quick restart and it would come back on no problem.

Yesterday the fans just kick on full blast and the display isn't working so i restarted it and it would turn on but the display didn't come on and the fans would run full blast again.

So I opened it up and pulled out my Graphics Card ( Radeon HD 6870 1GB ) and booted it up to see if that was the culprit. It booted up and the fans ran quiet nothing unusual as far as I could tell. So I figured I would put the Graphics Card back in and try to replicate the above problem. I put it back in the same pci e slot and reconnected the power in the same way I took it out. I booted it up and it runs the same as when I took it out, the fans come on they run quietly however the display is still not working.

Any advice on what I'm doing wrong here would be appreciated :)
