Please let me know how you will refund my shipping costs since the mobo was defective.

This way I put a good review on the product since all was as you said. If I don’t get my shipping costs then I feel I was lied too.

Hi,

I have installed the motherboard but nothing happens. The screen is dark and don’t see any lights nor and beeps or sounds from speaker. I also don’t see a speaker prong so I can connect s small speaker on mobo.

Everything starts good but nothing happens.
I tried a video card gaming on it and screen still dark. The video port on the back I tried but nothing.

I am thinking motherboard could be defective?
I know that when I installed everything correctly I should see the post screen but can’t. I also see that the hard drive light doesn’t come up. Any pointers there or?
