I'd like to ask your advice on a hardware issue I'm having. Let me start by saying, I realize the issue *might* be defective hardware; if so, then unfortunately I'm in a bad way, because I removed the graphics card's factory fan to include it in my watercooling loop. So, I just hope you might be able to think of something I haven't.
Okay, the issue: on a new build (Maximus IX Hero with i7-7700K), my graphics card (GTX 1080 Strix O8G) fails the POST when I start the computer after it's been turned off. Instead, the computer turns on using the CPU's integrated graphics. Heuristically, I find that if I let it run for about 10 minutes, then turn the computer off, disconnect the power, wait until the MB lights go off, then turn the power back on and start the computer, that the card then manages to POST and everything goes on fine. From that moment onward, restarting the computer doesn't pose an issue -- the card always POSTs fine. The only issue is when doing a cold start.
Just to cross off a couple of factors: this seems to be unrelated to whether I set the BIOS to utilize integrated graphics in the presence of a discrete card (because, if the MB doesn't find a discrete card, it defaults back to using integrated graphics).
I've seen online that quite a few people had similar issues with older models, but I didn't find a solution or a diagnostic of what's actually the cause for this issue (if it isn't just faulty hardware; but one person said that after sending it back on an RMA, they received word that the card was actually just fine).
Can anyone think of what might be causing this?
