Did I just fry my GPU?

When playing starcraft 2 with my friend, the game just suddenly froze. I have not had this sort of problems before. When I rebooted the computer I could not get past the login screen for sc2. Same with games like crysis 2 where it would hang when I get in game.
The problem is solved when I disabled crossfire mode. So does this mean I just fried one of the GPU?
When I had crossfire enabled, gpu-z also says that 2 cards are enabled. Any help is appreciated.

 

Try reinstalling/updating your drivers, re-enabling crossfire mode, and see if that fixes the issue.

If one gpu was completely fried, then it would be the slave and most likely the computer wouldn't boot.

 

I reinstalled catalyst 11.6 after doing a clean uninstall with driver sweeper. Problem still persists. Starcraft 2 crashed at login screen. Rebooted the computer and now I can't get past the windows starting screen.

 

use some other benchmarks like 3dmark vantage and GPUZ to verify.

 

I think it's time to call Dell. There's still a decent chance the gpu isn't fried, but that is what it looks like. At least we know its the slave and not the master.

 

I can get back into windows again somehow. GPU-Z shows thatcrossfire is enabled and sensors can detect two cards.
What should I be looking for in 3dmark vantage?

 

Make sure your vantage scores are normal compare to others'.

 

I ran 3dmark vantage and it gave me BSOD - a clock interrupt was not received from a secondary processor within the alotted time

 

What are your specs? Is anything overclocked? Are you using ThrottleStop? If so, return everything to its original clock. Reset the BIOS using the power drain method.

 

I got that BSOD when the tech replaced my slave card. The slave card had the factory Vbios and the master card had the latest VBIOS. I had to flash the the 2nd card to the latest to not get that error.

 

Good to know. You think I should reflash my cards again? They're stock, never had them changed or replaced.
No overclock on my cpu or gpu, not using throttlestop.
I did the power drain but problem is still there.

 

Ran 3dmark vantage fine with crossfire disabled. Could not run it with crossfire enabled. So, guessing problem with one of the cards.
Any other explanation that you guys can think of?

 

I think maybe you should flash again. Could be a bad flash but not to sure. The fact that Vantage won't run with CFX could maybe point to a bad CFX cable, but I am pretty sure, as the rest of the the thread posters are, that the slave GPU has gone bad.

 

just opened up the laptop and everything seemed fine. Would the slave card show up in gpuz if it's gone bad?

 

Yes, it is possible. You have to test your card individually.

 

You can also try to run furmark to see if anything BSODs. Also, what does it BSOD on?

 

What do you mean what does it bsod on? It bsod when I rani 3dmark vantage and sometimes when I run games in crossfire though most of the time the screen just freezes and I have to reboot the computer
