Hello, I purchased a main board through the large mystery box they sold so there’s a good chance there’s nothing I can do but I’d appreciate any ideas to get this main board working.
I have the Ryzen 7 7840 main board and I have it mounted in a bottom chassis with a battery, mid plate, and expansion bay shell with fans.
When I attempt to boot, the power button turns on for a second and the fans spin before both stop and after another second they both turn on again before this repeats indefinitely.
The lights on the side flash blue and red and after a minute I get a post code before it goes back to cycling.
The code shows green for all checks except the touch pad and the screen both of which aren’t attached. The post code after is 10000000.
I’ve made sure I’m charging through the back left port and I have a screen connected to the back right port.
I have tried booting with either of the 2 sticks of ram I have in either slot.
There is no current os installed but I have ubuntu on a flashdrive that I’ve tried having plugged in while booting with no change.
I’d appreciate any advice for this even if it’s telling me it’s a lost cause.
