Question Computer shut down abruptly and now won’t power on

[Craniumrat]

Hi, I was playing on my desktop and the computer straight up shut down. It refuses to turn back on.

The RGB LED lights work, but the power button or the mem test buttons on the motherboard do nothing.

Specs: ASUS Z370-A Prime.
Core i7-8870K
CoolerMaster MasterLiquid ML240L RGB.
Corsair Vengeance LPX 32GB

It does get hot in India (100 degrees) but I did not any burning smell or fumes from the machine.

Any idea how to go about troubleshooting this. I’ve been running this machine since June last year.

Whats the make and model of the PSU?

 

[Craniumrat]

Corsair CX650M.

I also have 2x Samsung SSDs, 1 Samsung NVMe, Zotac 1060 6GB and a ThunderboltEX PCI card.

I removed the graphics card, and took out and put back the CMOS battery. Still doesn’t power on. The motherboard RGB lights are on, but not a single fan is running. (AIO fan, case fans, power supply fan, GPU fans).

The cx650m is a good unit, however it could have failed.
I would strip the pc down to the basics and test it
1 ram stick
No gpu, use igpu
No expansion cards.
No drives plugged in.

Is it possible for PSU to be dead even though RGB lights are on?

Is it possible for PSU to be dead even though RGB lights are on?

Also, is 650W sufficient for my hardware? Should I consider getting a larger power supply?

What gpu do you have?
It is possible that the psu is partiallh dead and cant power the systems whe. It demands a ton of watts to turn on. Also like a single rail could have failed or something, but i bet the psu is ok.

I have a Zotac 1060 6GB. I removed the graphics card and tried to power on the system. One again, only RGB lights are on. Power on on motherboard does nothing.

650w should be enough.
Do you have a spare pau to dest with?

Hi,

I ran the paper clip test on the PSU as mentioned on this page: https://www.corsair.com/ww/en/support. The PSU fan turns on, so maybe the PSU is fine.

Any idea how to go about testing other parts of the desktop?
