CPU or Motherboard Issue

[Maxler]

A few months ago (before zen 3) I upgraded my PC. Since then I have been experiencing issues, ranging from application error, after which a game or program closes, to straight up BSODs. After a lot of testing I RMAed my CPU and Mobo but the retailer told me there where no issues. After trying the parts again the issues continued. After doing some testing myself I have concluded that is must be an issue with mu CPU or Motherboard. 

 

Through process of elimination I discovered that these parts where not the issue. I also give the reason why I think they aren't the issue.

- GPU: Works in different system with no problem.

- HDDs and SSD: Also work in different system

- Drivers: Updated them all and still have the issues

- PSU: Works in a different system

- RAM: Replaced with known working modules and issues persisted

 

So my question is, Is there a way to find out if the CPU or Mobo is the issue without the use of other hardware? I do not have those available at the moment. 

 

If anyone is able to help me it would be a great help as I am at a complete loss as what to do. I have debated on just buying a new mobo or CPU but I am a student and if I buy the wrong part it's a lot of money to me. If there are any suggestions on other issues I could have overlooked on the other parts I would be happy to hear to.

Welcome to the forums!!!

 

 

Have you tried clearing CMOS? If that doesn't work, I'd try a clean install of Windows since you replaced the CPU.

I have not tried to clear the CMOS. Windows I have installed multiple times, sometimes clean, sometimes from a backup so I don't think that will work.

 

The parts were new when the issues started, will the CMOS solution still work?
