Hello,
I just created my account because I really need help with my pc. First of all I'not completely new into pc's and I generally know stuff about computers.

I did the Windows 10, Version 1903 update I little while ago and since then my computer won't boot, this means:
peripherals won't light up, no boot logo (gigabyte) or in general display output. In addition one particular case fan starts spinning and then goes off, meanwhile my cpu fan goes to max speed and stays there until I shut the pc down by holding onto the powerbutton a few secconds. Sometimes the pc shuts down automatically after a few seconds, turns back on and stays in that loop.

I tried a lot of stuff: unplugging all fans (except cpu fan) because it could be a power issue -nothing
disconnecting the graphicscard -nothing
resetting the cmos -nothing
putting in a new cmos battery -nothing
updating the bios to the newest version -nothing

I found one way to use my pc normally: starting it and let it sit it the state I described above for ~10 seconds, then powering off by holding onto the pwr button, next remove on of the two ram sticks, power the pc again, then suddenly everything works fine, the one case fan doesn't stop spinning and the cpu fan goes from max speed to normal and the pc boots.
I thought okay it's a broken ram stick then. nope it isn't: when I power the pc off, put the ram stick back in and instantly power the pc, it posts and I can use my pc as always, no ram problems or an unstable windows.

I now have to do this procedure every time I want to use my pc, I hope anyone can help me.

I will put my DxDiag txt in here so you can find all stuff you need to know I guess, if you need more infos please just ask :)
DxDiag (the DxDiag says I only have one ram stick/8gigs of ram, normally it's two sticks with 16 gigs)

(sorry for spelling mistakes, I am german :) )

Kind regards Paul
