Question PC doesn't turn on ?

[hardware__desk]

Hi,

When I press the power-on button on my computer, it doesn't turn on, why could this be ?
I'm not a computer wizard, but I do know some things about PCs.

Regards.

Have you verified that it is properly plugged-in in the back and that the power supply toggle switch is in the on position?

Is this a new issue?

What are the specs (make/model of ALL installed components) for this system?

That is not the complete list of components. Details matter. Motherboard, power supply, storage devices, memory, it all matters.

Were you overclocking anything?

If you remove the GPU and use integrated video, does the behavior change?

Have you tried to disconnect the power switch and jump start the board shorting the power pins on the motherboard?

If it's been an issue for a while, you should try reseating some of your components like RAM etc and make sure that you don't mess with the PSU by yourself.

Why isn't it switching on?

I've tried that

Just to be clear when you push the power button nothing happens?
If that is correct then.

Flip the power supply switch to off then back on at the back of the power supply and try again.

Remove the power switch connectors at the motherboard and use a screwdriver to short those 2 pins on the motherboard, Google has plenty of videos on how to do that.

If that works then you can move the case reset connectors to to where the power switch ones were and use the reset switch to turn the PC on. (If your case has a reset switch)

I'm not touching the motherboard. But thank you for the help.

Get a friend with more experience to do it or take it to a shop if you can't do simple things nobody here can help you.
