Black screen when booting up...

Okay, I've encountered a problem with my M18x R1, specs in my sig. It was working fine yesterday morning but then the screen suddenly died down on me. The last thing I saw on its screen was distorted, mostly blue background. It seemed like it had a lot of artifacts on it as well. I decided to try and reboot it but nothing appeared on the screen. When I removed the HDD initially, it showed something on the screen but then froze after a while. I have tried completely draining the laptop of any power(removing the battery and holding the power button) and have also tried hooking it up to an external monitor(via VGA and HDMI). Nothing still shows on the screen. When I turn it on though, the keyboard lights up and I can hear the booting sounds. The fans are also working. I'm beginning to wonder if one of 6990Ms died on me(and if that's the case, I am through with AMD). I think it's a possibility but I have yet to test this theory out since I have no time to completely disassemble my laptop. I really hope there's a different way to isolate the problem. Any thoughts or suggestions you can offer me?

 

Sounds like removing the cards and trying 1 at a time is needed for this issue to determine if the unit has a dead card or if the mobo has kicked out.

 

Hi Codenamefa, is it possible for the mobo to be dead but still supply power? The keyboard still lights up. Honestly, I'd rather have the cards or ram be dead rather than the mobo.

 

As mentioned, it sounds like one of your gpu's has bitten the dust. The only real way to tell for sure is to do what was suggested above. Before removing/swapping cards, you could try and ensure that the crossfire cable is connected properly and try that. If that fails, you could try disconnecting it to see if the primary on it's own displays an image. If it does, the secondary is toast. If it doesn't, swap the cards around, secondary in the primary slot and retest.

Another thing you could try before playing about with the gpu's is to make sure that the display cable is properly connected too.....might just be loose....but the blue background you saw before it died is pretty indicative of gpu failure....

 

I'm with brother Jones, you will need to try the cards 1 at the time. Hopefully only 1 of them will give the same issue and you will just need to replace it.
