MAKE LOVE, NOT WAR




Problem description: A secondary computer was working perfectly fine last week. Today, it will not power on, with light identical to this blinking if the PSU is connected:

The thing is, it's not clear what that light actually "means." The AsROCK Killer Z370 manual is no help.

Attempted fixes: Cleared CMOS battery. Switched reset and power button headers to ensure it wasn't the power button being broken. Removed most components (video card, RAM...). No beeping noise when RAM is removed. Checked PSU wires were seated. I am about to try switching the PSU to see if that helps, but was wondering if anyone else had any ideas while I do so.

Recent changes: None.

Well, um:

1) Using another power supply (EVA Supersonic G5 Gold, 650) presents the same problem on this computer, plus the PSU's back green light blinks rapidly whereas it is usually solid.

2) Using this computer's power supply, the Seasonic Focus, successfully turns on another system.

So I guess it's not the PSU.

Is there some way to tell if it is the mobo or CPU, or do I just have to replace each one until this thing turns back on?

I totally parsed the thread title as user asrock z370 killer won't make posts on the forums. I apologize that this does not help you, but it amused me greatly. I wish you good luck on getting your chipset and or cpu to boot

I enjoy your merriment, it gave me a chuckle.

Usually when lights are pulsating like that it means the motherboard has been damaged.
