Hi, Im NEW into the DIY PC world and my new (1 month old)PC was working just fine yesterday. I just replaced my 3700x for the new 5600x. I also replaced my case because my 280 AIO didnt fit in my old one. Now, my PC wont boot fully: when I power on my PC cpu and dram red light turn on the Mobo for 5 secs - then the boot and the vga red lights come on. PC boots into black screen with Wind logo and Preparing Auto Repair.

hardware: ryzen 5600x, Auorus master 3080, Asrock b550 pro4, SilverStone 750w gold, crucial ballistix 3600 2x8gb

I checked the cpu it looks fine, no bent pins or anything, all the wires are in properly and wired correctly, changed the ram slots and tried using 1 ram in diff slots. all the fans and rgbs are good.

As i said in the beginning, im new and know very little. If u know the solution pls be elaborate. ty!
