I've been reading threads on this issue for the last half hour, yet none of them can fix my problem.
Recently I've been having my screen go black for maybe 10 seconds at atime, usually while gaming. Waiting a bit or moving the hdmi turned it back to its normal state. Specs here:
Radeon 7870 GHZ edition by XFX
Amd 6350 black edition (3.9ghz)
Seasonic 620W power supply.
GA-990FXA-UD5 mobo.

When I turned on my pc today, the on light came on, you could hear the fans turn on, but my monitor wouldn't detect any signal. When I switched to dvi, still nothing. When I connected my laptop via hdmi, it worked fine, so I knew my monitor wasn't the problem, but with no IGP I couldn't check the mobo, and it seems like my GPU is broken, even though its fan spins. Any suggestions?

Is the card overclocked? When the card is under to much stress, it will crash. Usually going black means its crashing. It could be too hot as well.

As for not even starting up, you could have fried it when you overclocked it, if you did.

If you didn't OC, then send it back and get a new one.

Sorry, never OCed this card. Its only a couple months old anyway, I doubt there would be much stress on it.

Ok, Update. I used another rig and swapped cards. I put a 280X in mine and no dice. When I put my card in the other PC, it worked fine, I saw everything, and it was low res b/c it had no drivers.
Now what? Does this mean it's a motherboard issue? Why does it only affect my gpu, and why do the GPU fans spin if it doesnt even give a dvi or hdmi signal off?

either the slot in the board is bad ( not enough power ) or the ps is not very good. can you swap out power supplies and try those cards in your machine?

Power supply worked fine before, I had to RMA a previous one, so this one's even newer, so I doubt it is the PSU. Also, I tried it with every slot in the board, none of them turned the screen on.

1) I would swap with the other rig the PSU as suggest just to MAKE SURE (we can't be absolute because we 'know' we need to test to prove things) it isn't the PSU
2) Your not getting BIOS correct? Your not indicating if your 'pass/fail' point is just not getting Windows or you can't even get BIOS. When testing hardware we don't care about software, we focus on hardware, and BIOS is the test point for anything.
3) If you tested the PSU and you can not get to BIOS then you need to 'BREADBOARD' everything. That means totally dismantaling everything out of the case and starting from scratch.
A) Place the mobo on a piece of wood or cardboard box
B) plug in CPU
C) plug in one RAM
D) seat GPU and if you can go as low as VGA to a VGA output that would be helpful, but I think HDMI would be choice #2 as the video connection here.
E) Plug in power switch from case to Mobo, then plug in PSU to Mobo ONLY
Can you get BIOS when powering on? If not then one part here is broken. As you tested the GPU we know it isn't that, and IF you tested PSU before then it isn't that, if you haven't then you would NEED TO NOW!
F) If still no joy with different GPU and Different PSU, then move the 1 RAM stick between different slots, any luck? If no try other RAM stick, again same process. Still no luck? Then remove the one RAM stick and power on, does system beep Error Code for problem with RAM, if NOT then the Mobo is probably DEAD.
G) stick RAM back in, remove CPU, power on, do you get Beep Error Code for CPU problem? If NO then Mobo confirmed dead, if YES then CPU is dead.

Either case if your getting down to F and G I would say dont' bother you need a new PC at this point. Seen i5 on slickdeals.net for only $349, swap the PSU and GPu and your good, for very little cost.
