I agree with Noktr 100%. I had this issue and i went through countless web sites and everyone would say either bad MoBo or bad PSU. my system would always do a hard crash, like i had to either hold the power button down until it turned off or in some severe cases pull the plug all together. in the future i will be checking that thermal compound first after the warranty is up, who knows how many other cards were made poorly

It wont show that it is overheating but i know it had to be overheating. i think the temp would spike too fast and cause the crash personally but im not 100% sure on that

I FIGURED IT OUT!!! I have been dealing with this for over 9 months with a BRAND NEW system I built following all of Linus Tech Tips videos. The system would just randomly crash from loading a game, all the way to being in the middle of a game and it crashes. I wasn't even playing graphically intensive games either! I had heard that it could be GPU, CPU, Motherboard, PSU, ... etc. I double checked everything in my PC... and I mean everything. I was 100% sure the GPU was fried and it was too late to return it. I had to swallow the pill of buying a new card in the middle of this bitcoin crap at the super high prices! It was about 2am my time and I was going to order the new card the next day when I decided to look for a fix. One. Last. Time. I found a very old thread, link below, that a guy was having the same issues. He did the exact same things I did and then some. He finally resorted to pulling the graphics card and taking apart and looking at it to see if there was anything noticeable. That's where the problem was!!!! The CHEAP way some of these cards are made, was causing this issue. More specifically, there was little to no thermal compound on the actual GPU, it was all on the board on the side of it. He cleaned it off, put it back together, and ..... Viola!! It ran fine! I did the same thing, also with the help of some of Linus' videos, and it fixed mine as well!! Just to note I'm running a Red Devil Radeon RX 480, so this is not a cheap card but also not a super high end card either. Hope this helps somebody save a little bit of money and not throw out their card when its just poor assembly. All credit goes to the guy that started the post in the link, without him I would not have figured it out. https://forums.geforce.com/default/topic/660409/screen-goes-black-and-gpu-fan-goes-to-max-speed-monitor-enters-powersaving-mode/
