Hello, I have a huge and complex problem.
My lame assumption is its caused by Motherboard. But I'm not a pro so I ask you:
First, history of the problem: I bought this PC in 2014, after 5 months my software equalizer stopped working so I checked why, and in hardware list my soundcard was listed under unknown manufacturer basic speakers. + front Jack 3,5mm played only Mono audio. Suddenly. I couldn't fix that so I live with it. After a year and half, my windows started to freeze randomly, usually restart fixed it but after few days it froze again and the time between freezes was shorter. Then I noticed I can't use search function in windows. Couldn't search in hierarchy of folders, could only search for a file I knew is in the folder I am searching in. That was weird so I reinstalled Windows but that didn't help. Random freezes were there and searching still didn't work, even when I installed windows CLEAN INSTALL from official windows iso I downloaded. On one freeze I restarted my PC and it said it The winlogon.exe is broken and NONE of the ways like fix windows boot, run command prompt and run commands to fix it there didn't work. Mostly it just said unknown error happened or windows cannot finish this operation, so another clean install helped. After this I had to reinstall the system like 10 times in 1-3 month intervals for similar errors (some windows file or necessary boot driver was damaged). Yesterday I tried to install the system again but it couldn't find my USB stick, I managed to find it by allowing CSM, but I never had to do this before. I also noticed my bios time was reset so I changed motherboard battery just to be sure. The installation was unsuccessful 3 times so I had to download the iso again (it was only 12 hours old). This time it worked but then I put my PC to sleep mode and after like 4 hours I heard *beep* sound, went to check my PC and on screen was written "running diagnostic tool" and then "your system cannot be repaired, press OK to shut the computer off" (sorry I'm translating from Czech). So I wanted to reinstall the system again just after one day it was working, now it won't find the Bootable USB stick even with all settings right, CSM on, secure boot off, only 1-in-30 tries the Bootable USB stick appears in bios but after restart it's gone again. I can't fit over this, I need your help guys. Will new motherboard fix the problem?
PS: when going into bios, my disks or all memory randomly disappears and shows N/A. After restart it appears again. Screens to compare: https://imgur.com/a/JfXa8
System info: on the screen above, I don't know where to find motherboard name.
Thanks for any help! I need to know what component should I change to fix this.
