Gigabyte Z390 Designare stuck freezy

[the Benninger]

Good day, this time I have a random problem, the computer freezes until I enter the BIOS and I can't turn it off because of the power button, the board in question is a Gigabyte Z390 designare, updated the bios to (F10) the problem persists

I'll be taking a step back with the bios by placing the previous version F9 if anyone has any suggestions, I was reading somewhere that you have to activate the XMP 1 profile because 16gb memory modules require more power than usual

best regards

I keep doing different tests the computer keeps working, I moved the video card to the second slot (PCI 8 Gen3) and it is working better, the power supply was already discarded and I checked the Mosfets and the inductor coils of the PLM, there is no failure of the power supply.

a series of things that happen randomly that gives a lot to think about, match yours if I use two memories it freezes or does not boot, if I use one sometimes it works fine for hours then it freezes, sometimes it does not even start, sometimes it turns on the memory LEDs (Kigstn Fury RGB) other times it does not, in the right corner where the four red LEDs are, when it works normally it does the following sequence (CPU-Memory-VGA-Boot)

sometimes when it doesn't start , first does (CPU-Memory) then it turns on again (CPU-memory) and it doesn't start in this loop I think it was a bad decision to have bought from the brand Gigabyte

I'm here to tell you
After all, if I was on the right track, it happens that when the computer came to me, there were no cables to provide power to the board for example; in the place of the cpu power connector this Z390 designare board, it has an 8+4 port where only the 8 cable was connected and it had nothing on the 4 pin, also this board brings another connector down to the right of 6pin PCI I imagine to power pci-e port and fans etc (this one was not connected either)I put in the missing wires but after having used the computer for a long time in this way, it ended up deteriorating the components, by the time I put the wires in it had been too late I imagine it lasted so long because the components were of good quality The result: a burnt video card and two memory sticks

here the new board I decided for one from MSI and everything is working correctly
