no display No display output error code d6

[MrFahrenheit451]

This is my first post here so let me know if I break any rules.

 

I tried booting this morning after I woke up and as usual I left before it finished to brush teeth etc. When I came back the PCs lights were on, the LED readout was showing CPU temp around norman but the fans on the GPU (EVGA 1080 hybrid) where spinning like crazy and there was no display out. I rebooted and this time it started normally, no crazy fans but again the monitors didn't respond, they didn't even cycle through inputs they just remained asleep. I shut down and rest the CMOS, after which I got the error code d6 which translates to "No console output detected". I don't have much else to troubleshoot with as my CPU doesn't have intergrated graphics and the only other gpu I have laying around is a GTS-250 that needs its thermal past replaced and likely doesn't work anyway as its been sitting in my room for nearly a decade. 

 

System specs are as follows.

 

MSI x99A Tomahawk

i7-6800k 

16GB (4x4GB) 3200Mhz 

EVGA GTX-1080 Hybrid

Antec Earthwatts 750W

Windows 10 Home 

 

The PSU was replaced recently but it's been working fine since. I'm fairly certain that the 1080 died though it was very sudden as it was working less than 12 hours ago and nothing happened since it was shut down last. I'm not sure if there's anything thing I can do other than replaced the card but I was hoping for a second opinion before I commit.

Hi, welcome to the forum.

 

Remove and reinstall your graphics card making sure it is installed securely

 

Disconnect and reconnect all MB and GPU power connectors making sure they are inserted fully and clipped into place

 

Try your MB's second bios. 

 

Reset the cmos(i know you said you did it but a lot get it wrong.)

 

Resetting BIOS to default values
1. Power off the computer and unplug the power cord
2. Use a jumper cap(screwdriver) to short JBAT1 for about 5-10 seconds.
3. Remove the jumper cap(screwdriver) from JBAT1.
4. Plug the power cord and power on the computer.

Reseating the GPU and the power connectors had no effect. Switching to the second BIOS had the motherboard hang on code b4 (USB hot plug) for about 15 seconds before settling on d6 again. Resetting using JBAT 1 also didn't work. The monitor remained unresponsie the whole time. The GPU is getting power, the EVGA logo on the side lights up and the fans spins, it just doesn't seem to be outputting. Thanks for the advice though.

I knew it was a long shot, the error code tells us the GPU is probably the fault, but it's always worth trying some basic and free troubleshooting steps first. I would definitely try the the GTS-250, it's something you can use to test now, if it outputs a signal you get your answer. it won't be on long enough for the paste to be an issue. Then if/when your able, you can test your system with a friends card and vise versa.

So I installed the 250 (The EVGA Hybrid is a pain to remove by the by) and was able to boot to windows so I guess we know for sure that the 1080 is dead. Thinking of replacing it with something like a 2060 super once I can afford it since they seem to be roughly equivalent but the 2060's much cheaper. Thanks for the advice, I don't know if I would've had the courage to try to 250 on my own as silly as that sounds. At least I an access my files if I need to in the meantime.
