Hi,
I want to post this here before I take my PC to a technician.

I have a X370 K7 motherboard, Ryzen 1800X, 16GB of DDR4 3200Mhz RAM and Aorus Xtreme 1080Ti rig that is not booting.
Windows is installed on an SSD.

When I click the power on button, everything flashes and runs for a mere second and then turns off. If I immediately click the power on button again nothing happens.
This has happened overnight. It's NOT a new system
I tried some solutions on the forums and nothing worked. many of which included replacing the motherboard battery, which didn't help even when I took the battery from my other Ryzen system and installed it in the first one.
I also disconnected and reconnected the RAM, the graphics card, and the motherboard power cable for a while, but it still wouldn't boot. Even when pressing the power button for 15-30 seconds.

I don't know why my PC won't boot, I have a 850W 80Plus Titanium rated power supply.

Is there anything I can do to get it to work that I haven't mentioned?

Thanks a lot

I also forgot to mention that my motherboard has 2 on board BIOS switches. I switched both of them but it still won't work.
Furthermore, my other Ryzen PC is now connected to the same power outlets as the one that is not booting.

Did you try breadboarding? Did you try powering up with only one stick of ram?

Please list your specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

You state you've tried many things yet you listed only two. Mind sharing what else you've done? Since you have a donor Ryzen system, please pas son two sets of specs lists.

The PC won't boot long enough to display anything on the motherboard's diagnostic digital screen. It's less than a second and then it turns off

I know you won't get video. But take the GTX 1080ti out of the build and see if the motherboard lights up on startup. If it does, seat the graphics card back into the mother board and see if your computer starts normally.
If the motherboard doesn't light up with the graphics card out of the build, reseat the memory and test for a post.

I've already done that, and unfortunately it didn't work. I took out the graphics card and tried booting the system but it didn't work. I also tried to take out 1 stick of RAM and boot it, it also didn't work.
The graphics card is running with no issues seated in my 2nd build though

I doubt you have to "Breadboard" your computer because it did work for an extended period of time and it's not a new computer. The only other thing you can do right now is go out and purchase a power supply to test with. If the test power supply doesn't work out, you can make use of the return policy.

I'm going to try to unplug and re-plug everything from the power supply, see if it works


Nope, it didn't work
