Hey All,
I’ve seen a few posts of this issue related to the AMD boards but not the Intel Core boards. I put an i7 Core motherboard into the Cooler Master case. I added an HDMI, USB-C, USB-A and Ethernet expansion cards.
HDMI → Monitor
USB-C → Power
USB-A → Keyboard/mouse dongle ( A Logitech K400 like we all have lying around 
)
Ethernet → Has CAT6 plugged in but primarily using it as another set of LED lights to see if the board is doing anything else. They do light up fwiw.
When the board gets plugged into power, the LEDs on the left and right start blinking right away alternating red and blue. I don’t need to hit the power button, they light right up when the power is applied.
In the AMD posts, I read that the board will do a memory check of sorts that can last 10+ minutes. I’ve had this little guy next to my desk for the last hour with no change. With this being an Intel board, I don’t know if it should act the same or not.
Also, unless it’s on by default, I did not adjust the standalone mode in the BIOS. I removed the SSD and one stick of memory to try and get it to respond in any other manner, nothing. The memory module is in slot 0 (left side as it’s labeled). I also tried both sticks I have. The modules I have are 32GB DDR5 (64GB total) and are actually going to go in my new AMD AI unit when it arrives.
I have a couple spare FW displays and batteries lying around. I don’t have a spare chassis tho. I could try to Frankenstein this together but I’m curious if there is something else I can try before I clear my workbench and cobble these parts together into something that resembles a computer.
If I do Frankenstein this, I’ll make sure to take pictures if it behaves any different. I figure the pics will amaze and awe some folks; and the rest of us may cry at the abomination.
