[SOLVED] [HELP] Suddenly can't turn on my PC

[vrephyr]

I just finished setting up my PC at my house, before this it was in my university's hostel. Long story short, I managed to run it and opened Spotify at the background. As soon as the monitor was turn off due to the power setting that I have set earlier that automatically turn off the display, my PC suddenly turn off/sleep as well.

It has been 3 days, my PC still cannot be turned on. I have tried various attempts to fix it such as;-

1. Jump start my PSU by using wire/paper clip on the 24 motherboard cable (4 and 5) holes. At first, my PSU fan was running, thus that indicates that my PSU is fine. However, on the 2nd try, nothing works... No respond from the PSU nor the fan.
2. Unplugged all the cables and plugged it back. Nothing works.
3. Using only single stick of RAM.
4. Removed GPU.
5. Latest was, I have tried using the Coolermaster Power Tester, no LEDs was lightened up when being tested with my PSU. Does that means my PSU is dead?

The weirdest part is, my LED signal on the motherboard still lights up. Orange colour which means the mobo is on standby mode. If my PSU is dead, how come my mobo can still light up its LED?

I need help and confirmation before I can really sure it is my PSU so that I can send it for warranty claim.
EDIT 1: I also felt soft electric current on my keyboard. Does this also means that my house has a wire grounding problem?

My PC Specs are as below:-
Intel i7-8700
Z370 Rog Strix
16GB G.Skill TridentZ RGB 3000Mhz
Galax GTX 1070Ti 8GB
256GB Adata NVME SX6000 Pro
120GB Crucial BX500 SSD
1TB HDD Seagate
CoolerMaster MWE 650w Gold Full Modular PSU

I think the most likely case is that the PSU is dead.

Especially if you get no lights with the power supply tester.

As far as the orange light on the MB.....it hardly takes any current to light that light.....so it still could be the PSU.

As far as the electric current on the keyboard....it could be the PSU causing that too.....but I would check the outlet to make sure it's grounded just to be safe.

Thank you for the clear insight.

I'm sorry for asking, but how can I make sure that the wall plug in my room is grounded? Certainly, the electric current can only be felt if I installed my PC at my home but when I'm in my university's hostel, it was all fine no zapped feeling or anything.

Get an electrician to check it --- we can't be encouraging non-qualified people to go messing with stuff like that.

If you have a multimeter.....you can check to make sure the outlet is grounded.
Set the meter to "resistance" mode.
Place one probe on the ground terminal of the outlet.
Place the other terminal on a known ground.....like a water pipe.....or a beam that goes into the ground.....etc.
If it's grounded correctly....the meter should show near zero resistance.
If it's not.....the meter probably won't change.

"If it's not.....the meter probably won't change"

I don't like to see the word "probably" where electrical instructions are concerned - - - not very reassuring - -
Is why I recommended a qualified electrician be contacted. I stand by that recommendation.
