My computer won't start unless I disconnect or power off the PSU and restore power. I've already replaced the PSU, which also came with all the cables for the motherboard. I also swapped out the RAM and checked all connections. I tried booting without the GPU connected as well. I'm using Windows 11. The BIOS is fully updated, along with all other programs and software updates.
Which PSUs are the same or different models? Was it functioning before? Did you replace the cables with those from the new PSU? Check the RAM for errors using memtest. Replace the CMOS battery.
Additionally, both sfc and dism were confirmed to be in good condition.
When the PC fails to start initially, are there any beep codes or diagnostic lights? (You might need to connect a small speaker to the motherboard to hear any beeps.) When the PSU has been running, what is your shutdown process? Disable all power and screen savers, etc., to see if it makes a difference. To rule out possibilities, check Reliability History/Monitor and Event Viewer—either tool may detect error codes, warnings, or events linked to start failures.
Just to confirm: you right-click the Windows icon (typically in the lower left corner) and choose "Shut down or sign out," then proceed to shut down—correct? After that, do you power off any additional switches?
What steps do you perform to eventually bring the PC back on?

Check Reliability History/Monitor. It’s more user-friendly than Event Viewer; the timeline view can highlight patterns in events.
Each entry can be explored further for details, though they might not always be useful.
For reference, open Reliability History/Monitor, expand the screen to view all data clearly.
Adjust the view to Days and pick a day with the highest errors, etc.

Correct. I powered off from the windows. I have also unplugged everything except a fresh keyboard, mouse, and a new display port cable. Still the same problem.
I consistently resolve the issue by performing the necessary steps. The power supply for the PC/PSU is determined through various connections such as wall outlets, extension cords, power strips, surge protectors, or UPS systems. Are there additional devices sharing the same power path?
