PC logged in a couple of times while setting up, but now it's not working.
Hello, I’m working on assembling my first PC and things have taken an unexpected turn. Initially, turning it on worked fine and the BIOS loaded properly. After powering it off and trying to restart, it stopped responding. After several attempts—reinstalling parts, reseating components, and even using Flashback to update the BIOS—I managed to get the system back online. However, this time the display only appeared briefly before the screen went dark and the machine shut down. Now, when I press the power button with a screwdriver, both the CPU and GPU fans spin, but the monitor fails to show anything, even though it works on another device. I’ve followed all the steps mentioned in the forum thread except for testing RAM and GPU on another machine, and I haven’t used the debug speaker. The build photo is attached for reference. My hardware details are listed above. I’m really puzzled by this issue.
