I just finished my new PC build yesterday, installed windows, and downloaded the GPU drivers as well as a MOBO update and then had to run to work. While I was out my brother used it a little bit, but not for much, twice while he was using it the display went black and he had to restart the PC to get it working again (best explanation I got from him). When I got home from work I booted it up into the BIOS and had it freeze on me in the BIOS. I waited about 2/3 mins and decided to restart it, it wouldn't post, showing the VGA qLED.
Ive done a fair bit of troubleshooting, resetting the CMOS a bunch of times, both by shorting and by removing the mobo battery. Ive managed to get it to post twice, once having the screen freeze in the bios and the second time booting it straight to windows ignoring the bios and having it just shut off on me. Ive removed and remounted all the components except for the CPU (mobo, GPU, nvme ssd, ram) without any luck at solving this problem. Ive tried using an old rx 580 gpu that I know still works, I've tried putting the GPU into a different PCIe lane, I've even tried running with no GPU using the motherboard's HDMI output (although I dont think my CPU actually supports this).
Any help/troubleshooting suggestions would be greatly appreciated.
Thanks
