Question Computer not booting & no fans are spinning ?

[Ukhguk]

I was playing gta v and was a blue screen and the computer turned off. I opened it the rgb light stays on the motherboard and their is a green light. When I use switch on the motherboard using the power switch on the motherboard the green light turns off after a while. I have already tried resitting cpu, cooler and ram. No luck any ideas. None of the fans spin. Any help will be appreciated. Thank you.

Specs:

I7 9700k
Z390 prime a
16gb ddr4 ram
Corsair rm750x
Msi rtx 2070
500gb samsung evo m.2 drive

Try a clear cmos.

The green led points at the boot device/ssd.

the rgb light stays on the motherboard and their is a green light. When I use switch on the motherboard using the power switch on the motherboard the green light turns off after a while.

What onboard switch? There is no power switch on this motherboard, unless you mean you short the two pins of the front i/o meant to start the pc ...

You can take out the RTX 2070 and try the onboard gpu (back i/o) for the trouble shooting for now.
