Hi, your i7 9700KF on an ASUS Z390 Prime 8x2 DDR4 SEASONIC Focus 650W Gold stopped working after a game. When you power it up, the PSU clicks on and then turns off right away. The board stays lit even when the PC is off, and the fans spin briefly before shutting down again. After unplugging everything, testing RAM, clearing CMOS, and removing the motherboard battery didn’t help. Nothing seems to work. Can you try testing the PSU separately? What might be causing this issue? I know a bad RAM should prevent booting.
Requires specialized equipment. It's best to use a reliable model and test it there first.
Remove your graphics card to check if the system starts properly (without a display connection). I experienced the same problem last month, where my computer would shut down unexpectedly and fail to restart. I attempted standard troubleshooting steps like checking RAM and clearing CMOS, but the issue was resolved when the graphics card failed internally, likely due to a short circuit. If this matches your situation, you’ll likely need to replace the GPU.
The 9700kf lacks built-in graphics and will not start without a dedicated graphics card.
Yes, the system didn't start, the power supply cut off right away, I can tell by the sound. It makes a clicking noise when it powers up and turns off.
In your scenario, it seems like the issue might be with the power supply unit. I thought it would be wise to suggest taking out the GPU, as your problem closely matched what I experienced.
