Question Computer wont start at all

[Cheuie]

So two days ago my computer worked like a charm and when i was going to turn it on the next day it didnt want to start. I have no idea what has happend between two days ago and yesterday. When i try to start up the computer nothing happens and when i connect the power cable and turn the switch on the PSU the motherboard will light up for less than a second (as it always have) and nothing happens. So i wonder is the motherboard bad or some other component that is bad and stops the computer from starting at all?

Spec

• Motherboard: z370 aorus ultra gaming
• CPU: I5 8600K
• GPU: MSI GTX 2060 Super

What i have tried

• Reset CMOS
• Change CMOS battery
• Changed PSU to see if it was bad
• Took all component out and connected only the necessity.

Possibly start button switch, try with a screwdriver to momentarily connect posts on MB for it, or connect Reset button to it.
