Yes, problem solved! It’s the motherboard!
Next time I’ll build my own PC !
thank you
Great. Glad the long saga is over:
So, soon you are going to compete with Acer? But remember, building your own rig all by yourself is not an easy task. It is known to be one common cause for hair loss ... you will pull so much of your hair out of frustration . Just kidding . It is not a rocket sciene any more and you'll have the satisfaction of choosing the parts you like and the look and feel you want your computer to have.
Good luck.
