I got my GTX 1080 Ti SC2 from EVGA last week and it has been working flawlessly across all the games I've played even when overclocked to 2,000 MHz on the core and 12 GHz on the VRAM. However, last night when I turned my PC on instead of seeing the UEFI screen briefly before my PC loaded into Windows I saw a black screen although the drive activity light was on. The Power button wouldn't work on the case to turn off but hitting Reset booted into Windows the second time without any apparent issues. After turning my PC off last night then same thing happened again this morning: a black screen and again pressing Reset on the case booted into Windows the second time. What is causing this? It seems unlikely to be a PSU issue since the card works 100% fine in Windows and I've not had a single crash or anything like that playing any game. I do recall seeing threads from GTX 1080 owners experiencing the black screen issue on starting their PC... not sure if that was a driver or Windows 10 Creators Edition issue though (not sure how software can cause a black screen immediately on turning on the PC though and before it has even loaded anything). Any help would be appreciated. I don't think the card itself is faulty otherwise I would have experienced problems with running games by now (I played Mass Effect: Andromeda for 10 hours straight on Monday for example with no problems and benchmarks all ran fine). Thanks.
