Windows 10: HP 22 all in one gets power but won't boot up

Lights up in back so it's getting power, will not boot up. When hit the power button to fire it up I get nothing. No beep, no monitor, absolutely nothing. Help! I've tried the fixes I found online, disconnect power cord from computer, hold down power for however many seconds, plug back in and I still get nothing. It's only about 2 years old.

Hp laptop screen won’t display except occasionally

I would like to note that step 20 comes up with no files. Perhaps this could be the source of the issues?

Kursah, that 6 steps are granted it always boots at the 6th step (sometimes at the 4th) and I have to remove the ethernet cable every time otherwise I'll have to do countless steps, that's a fact. I do not have Wake On Lan set.

I would still say try a different PSU... here is a solid budget power supply:

Interesting with the NIC connection...not sure what to make of that. What are your system specs? Make/Model of all your components? Check my system spec's for an example.

Honestly I would do process of elimination to another step...and that step would be the PSU. If nothing changes after that..I would try to force flash the CMOS if possible..to ensure no corruptions lie within that.

I would also try as I suggested above and try to boot with minimal hardware... you need an STDIN...Keyboard, STDOUT...VGA, CPU, stick of RAM and power to be able to perform POST on the mainboard. So starting with that would be a great place to go next.

If nothing changes..depending on what you're running a different CPU might be the next step... by the time you're done...you might have built a different PC. But you'll also have more experience in PC diagnostics which is a huge plus for odd issues like these...wish it was in front of me so I could examine and diagnose.
