Okay so as the title states I am having some trouble with my 7970. Let me get a bit of background out of the way. About 6 months ago I ordered my computer through iBuyPower. My computer has run great for the last 6 months without a hiccup until 2 weeks ago. I tried booting up Planetside 2 and it said that I had to graphics card installed, I thought that was weird and tried loading Skyrim to make test it there, sure enough it said I had no GPU as well. Now at this point I thought that was really strange and decided to just to a quick restart of my computer thinking maybe drivers didn't load properly or something. And that is where things seem to go bad. On reboot things look normal until it gets to the Windows 8 boot screen, you know the screen with the blue windows logo and the spinning dots on the bottom. After that my LED screen goes black and starts to turn the LED backlight on and off, so its flashing on and off on a black screen and it will continue to do that indefinitely.

Now I contacted iBuyPower about warranty information and they said it sounded like a dead card, so I packed my old card up, sent it to them and received a new PowerColor 7970 in the mail today. Plugged it all in and the same exact thing is happening.

Hoping you guys can help me sort out what the real issue is. I know PowerColor is not the most reputable company for cards but its what iBP sent me so its what I have had to deal with, not my choice on that one.

Is there a fix to this? Should I try iBP one more time for another new card? Should I pony up and maybe buy a new 7970 from another manufacturer or get a new GTX 770 and just take the $300-$400 loss? What do you think I should do?

I can also make a quick video of what is happening if that would help.

You dont necessarily have to take it out to test another PSU in it. But you can try the 770 first and see if the problems replicate themselves with that. I would think they are similiar on their power needs, the 7970 and the 770.
I would test your PSU before you do anything. Unless you specify another PSU for your build, isellcrap usually puts in a garbage PSU. Unfortunately it happens to a lot of their customers. Try another PSU and make sure it is a known, solid brand like Corsair, Antec, Seasonic, something along those lines.

Do you really think the PSU would be causing this kind of issue? I'd rather try and borrow my friend's 770 and see if it works before I go and take out my PSU, the thing has some hardcore cable management going on

So I dont know what I did different but I decided to try putting my card in again but in a different PCI slot, and it worked. Now I was happy with this but decided to try the original PCI slot and it worked. Don't know what was wrong, but it seems to be working now, not sure why

Thanks for the help guys
