Monitor no signal

HP Recommended
Omen 30L GT13 - 0024 PC

I bought this pc a few weeks ago and all was well until it suddenly stop sending a signal to my monitor one night as I was watching YouTube. Now when I power the pc on, it'll boot up and shut off immediately and power itself on again withing seconds. Aside from the monitor issue I also am not getting connection to my mouse or keyboard. This is my first pc so I'm not too knowledgeable on what to do.

A dead PC that is.  NO signal; , and PC fans dead.   (hold power button for 10seconds PC release might wake it up)

a dead PC has no working mouse or keyboard, it is dead. NO POWER DEAD.

the PSU shuts off, for many reasons

I will list them all and the test to  find it.  yes, fixing any machine , we do tests, to find problems.

1: PSU is sees a gross power (DC RAILS) overload, and shuts off before the fire ensues. (by law and smart) even under 1 second  max, per ATX spec or less.

2: PSU  IS BAD (we assume that last or bench test  it, using a jumper clip.(and a DMM volt meter)

3; the PCis just overheating and the CPU sees that at about 90c all CPUs made P4 up shut down to save its expensive bacon.  even modern GPU do that too, now. self protection and at 80c or about  the CPU self throttles itself to lower heat waste ..(production) run hwinfo32.exe for free see how hot things get?, zero risk and true free, for sure.

 

that is it.  to find #1 we do the strip down test. (even USB device can sort remove them first)

NO warranty answers by me.
