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
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.
