Such a new PC should not have such troubles. Back to the seller and makers to correct this issue or get a refund so you can shop for working hardware.
I built my computer 2 days ago, but couldn't install Windows, because I needed a driver.I installed a driver hoping to get all the drivers needed for me to download Windows. So this being said, I do NOT have windows. I also the VGA cable is working, because it's detected and was working. However I am wondering, what should I do? I am so lost, because my monitor doesn't show ANYTHING. I can't get into bio, etc.
EDIT: I think it may have to do something with a graphics driver I installed for my cpu (i5 4690k). It stopped working after I plugged the USB with that driver on it.
