Hi. I built my new computer yesterday. To begin with, it booted up fine. The first time I powered it on, it turned off and on again a few couple of times. But eventually I got into BIOS where chose to run an XMP. Then i let it boot into windows (I kept the storage from the old setup) and it was working fine. I updated some motherboard updates and so on and restarted the computer. This time it started perfectly. Then I decided i'd try to play some BFV on it and it opened the game just fine. After a few minutes before I could get into a game, the screen went black and the fans started going 100%, all of them including the graphics card fans. I then forced the computer to shut down and when I tried turning it on again, it wouldn't start. It would only be on for a millisecond to 2 seconds. I then discovered that if I disconnect the GPU from the PSU, it would start. It may take a few tries like the first time I started it, but It would stay running. The fans keep going at 100% with the GPU disconnected, I tried re-installing windows 10 as I could still use a screen via the motherboard display port, but now I have no internet connection on it. Anyone have an idea what to do?
