[SOLVED] Some part faulty in PC but dont know which

[Florian99]

So hello Forums. I am pretty on the edge since my PC basically stopped working normally but i Need to work on it right now.
At first i got only a few freezes in Windows. These were Lasting for about a Minute but then went away and came occasionally but day after day it got worse now so it is almost every few minutes a full freeze in which i cant do anything. Sometimes i cant interact with the UI, sometimes just nothing but the mouse wont react and also the Situation when even the mouse wont react. Even while writing this it happened 2 times. I already set up Windows completely fresh so no Software Errors. Isnt the SSD as i also fresh installed on another HDD. So i am now at my End. What can I do now? It could be The PSU, MB or CPU. It isnt Ram either tried 1 stick at a time and same error. I could try another PSU in a few days just to try if this isnt it.
Hope some of you can help me with this.
Greetings

Update your post to include full hardware specs and OS.

Include current PSU: make, model, wattage, age, condition?

When the PC is initially working immediately look in Reliability History for error codes, warnings, and even informational events.

Run the built in Windows 10 troubleshooters. The troubleshooters may find and fix something.

Run "sfc /scannow" (without quotes) via the Command Prompt.

Power down, unplug, open the case.

Use canned air to blow out dust, debris, dead bugs, paper scraps, hair, etc.. Follow the instructions on the can.

Ensure that all cards, cables, RAM, jumpers, etc. are fully and firmly seated.

Ok now i have updated the post with specs.
Cant be a Software error as of multiple Fresh installs of Windows 10 on 2 different drives were tried with same fault.
Also PC is not overheated and not much dust in it. Today I took apart my PC. All conectors should be tight.

It is solved now. Bought new Mainboard and replaced it. So the MSI B350 only held for under 3 years... Everything is fine now.
