Problem:
When I try to power up my system, nothing happens! No fans come on. No boot activity. No disks spin up. No codes display on the motherboard's LED pad. The decorative LEDs are on as long as the Power Supply Unit is on.
Considerations:
In addition to both the decorative and diagnostic-code LEDs, the motherboard is equipped with an onboard power button (illuminated red), a reset button (illuminated green), a red Clear CMOS Button (unilluminated basic button), and a black Memory OK button (unilluminated basic button).
Here's what I've tried so far:
So does anybody know what would cause this? I've been searching this forum, Asus' forum, and several others for two days, but not found a solution to this situation. Some others have posted similar issues, but no solutions.
Any suggestions as to what to try next in the troubleshooting process?
System Components (running Windows 10):
It would gall me to have to take this to someone for a test. Any help would be greatly appreciated!
When I try to power up my system, nothing happens! No fans come on. No boot activity. No disks spin up. No codes display on the motherboard's LED pad. The decorative LEDs are on as long as the Power Supply Unit is on.
Considerations:
- The system has been in use with normal operation - This system was built in May 2018 and has been running with NO ISSUES since that time. Suddenly I go to use the system and I find it powered down (last used about 2 days before and it was left powered up) and it will not boot up or go into the Power On Self Test (POST).
- It has not been fiddled with or modified - No changes were made to the system, and nothing physical was done to the system in the interim unless, you know, some meddling kids broke into my place and did something to it, then slipped out quietly. I realize that sounds stupid, but at the moment it's my leading suspicion for what could cause this.
- It has power - The motherboard has decorative LED lights that are on and glowing normally, but the system will not boot and the diagnostic LED code panel does not come on or display any codes.
In addition to both the decorative and diagnostic-code LEDs, the motherboard is equipped with an onboard power button (illuminated red), a reset button (illuminated green), a red Clear CMOS Button (unilluminated basic button), and a black Memory OK button (unilluminated basic button).
Here's what I've tried so far:
- Disconnected all external drives - No effect.
- Checked all connections to the motherboard - No effect.
- Replaced the power supply unit (PSU) with a known good PSU - No effect (Original PSU is now reinstalled).
- Unplugging / replugging then:
- - A. Using the motherboard's power button - No effect.
- - B. Shorting the power terminal posts on the motherboard where the case's power switch connects - No effect.
- - C. Holding the motherboard's power button down for over 10 seconds - No effect.
- - D. Holding down the red Clear CMOS button for over 10 seconds, then reattempting the motherboard's power button - No effect.
- Note: When I unplug / replug and attempt any of the power-up options, I can hear a faint and audible "click" sound from somewhere inside the case, but I don't know where. It only sounds once per attempt unless I unplug / replug first.
- Moving / Reseating the RAM sticks - No effect.
- Unseating the Graphics Card and attempting to boot up - No effect (Graphics card now reinstalled).
So does anybody know what would cause this? I've been searching this forum, Asus' forum, and several others for two days, but not found a solution to this situation. Some others have posted similar issues, but no solutions.
