[SOLVED] Is my PSU faulty?

[somekiwiboi]

Ok, so of recent my PC when I try and boot it takes 2/3 goes before it finally boots to the desktop, I am wondering if my PSU is faulty because of this and both me and my dad agree there is a slight burning smell coming from it I know this is probably a dead give away but want to know for certain before I get another one. Also wondering if my bios is corrupt so how would I check that as well?
Specs:
PSU: Cooler Master 650W MWE Bronze
GPU: Gigabyte Geforce GTX 1660
CPU: Intel i7-9700k
MOB: Asrock Z390 Phantom Gaming 4

Can you clarify in detail how the computer react when it does not succeed booting?

Why do you think the bios are corrupted ?

It will just sit there with Asrock on the screen till I turn it off and then back on and so on

Read it somewhere trying to find the problem

I'm wondering if there are some messed up sleep / suspend settings. Does the problem go away if you cycle the power when the cord is unplugged, then plug the cord in again and power up?
