My PC is not booting after building

[Julius_Peters]

Hello,
I build my PC a few days ago and one day after the PC is working some of the voltage converter on my Motherboard goes on flame. Then I bought a new Mainboard and install all again, but now if I press the power button, the fans of my PC is going on, the LEDs of the Motherboard turns also on but nothing happens and after a few seconds the CPU fan also goes of and it shows also nothing on the monitors while this whole process.
I need help and I would be glat if someone helping me

Hello

Give us your complete pc spec’s and the psu as well. Explain the tweaking on the voltage converter.

I read in the userguide of the mainboard, that the red LED that is blinking stand for the CPU so I changed the 8 pin cable of for the CPU and the PC is about to go on but still not boot or show something on my monitor. In addition now is a yellow LED blinking which means, according the userguide, that something is wrong with my RAM…
My specs are:
Mainboard: Asus ROG Z690-F Gaming WiFi
CPU: Intel Core I5 12600k
GPU: MSI GeForce 3060ti Ventus 3x
PSU: BeQuiet Pure Power 11 with 600W
RAM: Kingston Fury DDR5 16GB 6000mhz

Pull one ram stick at a time to test ram on startup..

Sorry I am not getting emails from this site
Are you sure your thermal paste is done correctly?
Which ram slot are you using
Use 1 ram at a time in slot A2 - Pic attached
Remove the graphics card and connect to the onboard graphics

[PeterOz]

Also make sure bios is set to defaults

and if still no luck, dismantle it all and reassemble (without the case) onto a piece of cardboard on the floor or some bench.
not only will this give you the chance to double check all the fittings and cables, but it makes it easy to swap components in and out and generally check things until you get it worked out.

@Julius Peters - any progress?
