I turned off CSM support and updated the platform key. Now pressing the boot button causes fans to speed up, slow down, and then stop, but the display remains dark with no input. What should I do next?

I attempted to use CMOS settings several times and didn’t see any changes. I also removed the battery to check if that helped.

Taking out a single stick of RAM may also cause your BIOS to start with default settings. Reinstalling your graphics card is safe as well.

It didn’t matter at all—the PC began using the GPU, the cooling system kicked in, and the fans adjusted their speeds, but the video output remained absent. I tested the monitor on the laptop and it functioned properly, confirming the issue was with the PC itself.

We're sure it's posting. There are no debug LEDs or a speaker sound on the board, and it appears on the network.

That indicates the fan is functioning properly during startup. The brief on/off cycle suggests it resets or checks itself after initial power-up.

They should indicate which component is active during the POST process—CPU, RAM, graphics, or OS. If an issue arises at any stage, a corresponding POST code will appear through beeps, LED signals, or other output methods.
