No display signal from GPU

Ive been having some gpu problems and it seems it might have died on me. Whats the best way to check if its actually dead and if theres maybe some possibility of fixing it?

Basically this is what happened. Two days ago i had a hard freeze while playing a game, it appeared as grey bars and very short looping audio. I have my r9 280x overclocked to 1,1ghz but no voltage oc still i figured it might be the problem so i returned it to stock. Worked fine for 2 days but today the same freeze with grey bars happened followed by no hdmi signal from my monitor. I shut down the pc and turned it back on only to find it wouldnt give me display signal even after hearing the windows notification sound from an update scheduler. I am now running on intel graphics thru a vga cable. I need to find an adapter from vga to dvi since my gpu only has dvi but monitor only vga still im afraid changing ports will not fix it. The gpu also has a bios switch and i tried both settings and no difference. 

I am going to try another PCIE slot but does anyone else have any other suggestions?

Wonder if its over heating possibly? Try putting new thermal paste on it and testing it out. If overheating is not the problem, it could be a driver issue as well. Go download DDU, Link Here and follow the instructions. Afterwards, go downloaded the latest available driver and try fresh. If these dont work, then it is likely that your card is indeed likely dead.

No thats definitely not an issue, i check temps constantly an it was under 80c yestreday. I guess i can try a driver sweep and install fresh drivers since i can run the pc on intel graphics

it could be anything from RAM to PSU, if your PC has an integrated GPU then take out the graphics card and use the integrated one. if it works, then it is either the card itself, the PSU (I had that once, my PC mostly worked, apart from the GPU, but the GPU did work in my new PC, it was the PSU that went bad) or it could be the PCIe slot

So ive managed to get it to grab the signal but it crashes after being 10 minutes under load. Ill grab a psu from a friend and see if that fixes it.

If that doesnt do it what are my options? Is the oven solder reflow thing still considered a viable fix? Even if just temporary
