Left PC for 2 weeks for vacation, now it wont turn on

[bwandowando]

So I left my fairly new PC for a 2 week vacation and when i got back, first few times I tried to boot the PC,it doesn't turn on at all.

I removed the cables, replugged em, and eventually it did turn on,and used it for a few hours, then went to sleep.

This morning, immediately after waking up, PC wont turn on again regardless of how many times I removed cables, etc, etc. I swapped outlets, removed cables, etc. I also noticed the led of the bios flashback is continuously blinking like 1 blink a second. I searched the forums and found a similar case https://rog-forum.asus.com/t5/gaming-motherboards/rog-strix-z790-f-gaming-wifi-won-t-boot-up/td-p/97... but it doesn't say what happened after

What makes it boot though is that I have to remove the PSU's cable, then after a few minutes, plug it and immediately press the power button. The PC would bootup as of nothing happened. But everyone I shut it down, even after hours and hours of seemingly normal operation, it will again unable to boot and I need to do the remove-the-cable-trick.

Any ideas?

My specs

• rtx4090

• Intel 13700k

• asus z790f

• wall outlet -> servo AVR -> 1500W power supply

Hello, @bwandowando , @WisKomp and all 

Thank you for providing the relevant information and for your patience.
We tested the same hardware configuration for nearly a week but couldn't replicate the issue you described.

EDIT: 
After thorough consultation and verification, regarding the situation where the BIOS flashback LED indicator flashes simultaneously with the inability to boot, we recommend further contacting your local customer service to arrange for repair or initiate an RMA for maintenance.
