i7-8700 + 5700XT Freezing for few seconds

[koji]

Hi, I hope someone can help me troubleshoot the issue. My PC freezes for about 3-10 seconds randomly. Sometimes when I'm watching youtube, or watching some local videos, or launching a game. (I haven't tried playing a full game yet).

Here's a video I took when I try to launch Euro Truck Simulator: https://drive.google.com/file/d/123890L_Dev_KhMMekF4roXUV9K0En04V/view

 

My specs: i7-8700, Asrock Z390 Steel Legend, RX 5700 XT Nitro+, Seasonic Focus+ Gold 750W

I recently changed hardware from: i7-8700, Asrock Z370M Pro4, GTX 1070 EXOC-SNPR, Seasonic Focus+ Gold 750W

 

I dont know if this has any relation to what's happening but my old hardware had problems with the GPU and Motherboard which is why I changed them.

Here's the thread for the issue of the old hardware: https://linustechtips.com/main/topic/1126446-i7-8700-pc-wont-work-without-dedicated-gpu/

 

I also have a Seasonic SS-520FL 80+ Platinum 520W PSU and I did use this and the Focus+ alternately to see if it's the PSU causing the issue but it's not.

I also checked the PCI Express Link State Power Management under Advanced Power Setting to make sure it's set to OFF. Then set the power setting to "High Performance"

 

Please help me troubleshoot the issue.
