Weird troubles

[VA2LRM]

Hi guys! I have no ideas for my next step.

 

For the last 3 months, I'm trying to point what's wrong on my machine; games are always crashing, youtube videos pixelating, etc.

 

I tried changing my aging gtx480 for a gtx760, thinking that she was the culprit. Then I changed my cheap SSD for a Samsung evo.

 

I tested my ram thru memtest86 with a bootable usb image, to get rid of windows nonesense, tried multiple CPU test software and I'm having the same issues....

 

I have the lastest drivers and BIOS updates... What's the next best move ?
