Welcome to the forums, newcomer!

Try and relocate your PC to another wall outlet and see if the issue persists. What BIOS version are you currently on for your motherboard?

I was once faced with this issue at work. There is most likely something wrong with the outlet, or UPS, that the pc is connected to.

Thank you. Two days ago I have changed my outlet accordingly but still encounter this problem today. I have reached out the mother board customer support and they ask me try to restore the bios setting or clear the CMOS.
My mother board version is ver.4201 which should the latest one.

Also, if I only disconnect the outlet but not switch off the PSU, my PC still won't power up. Meaning the only way to power up is to switch off and on the PSU.

Still facing the same issues even I clear the CMOS.

Hello All,

I lately read some articles about the DisplayPort cable 20 pin issues. Would it be the issues of mine and how can I checked if my DisplayPort cable 20 pin is connected.

Hello Guys, it's been weeks since my last post.

After my third try to change a new DP cable, my issue hasn't occurred to me after one week. Seems like the issue is due to the DP cable.

DP cable? Sorry, don’t recognize the term.

Sorry if there is any misunderstanding. It is DisplayPort Cable.
