Hi.

I've had this build for 5 weeks and it has been working almost flawlessly ...until today.

The computer froze while I was doing virtually nothing, just a browser open. The screen went completely black and I could not turn it off via power button, I had to use the PSU switch.

The reason why i said almost flawlessly is because this has happened once before, around 1-2 weeks ago. But back then the computer would turn itself on normally, now it's completely dead. No beeps, no fans starting, nothing.

I've read through the troubleshooting guides and so far I've only been able to exclude the power cable, however there is one thing that could hint where the problem lies:
When I turn on the PSU the motherboard's LEDs will light itself on for a brief second then go dark.
Is this normal or could be a sign that my motherboard is the problem?

I just pray to God it's not my $1000 GPU. Thanks in advance!

Specs:
i5-8400
AsRock Z370 Extreme 4
16GB G.Skill Ripjaws
Seasonic Focus+ 650W
GTX 1080 Ti

Most likely something going on with the hardware! If after all the ideas you have tried here go back to the basics.......... disassembly your PC and place the motherboard on some kind of insulation. Only install the power supply (video card does provide variable so if the cpu have built in video remove your video card) and then no boot device. Make sure nothing is attached. It should post, will take a long time and you might get a keyboard error. Any peripripheral can create a problem. Some BIOS don't post well without a keyboard so try a keyboard first. Everything else removed. You get the idea. Even a short from the motherboard to the case or improper grounding can cause a problem.

Thank you for your answer!! In the meantime I was doing some tweaking and re-seated the RAM from 2 and 4 to 1 and 3.
Computer turns on now! Only showing 8GB of RAM right now but half of the problem solved :)
