I'm using a used hard drive from my previous pc that is already formated. hear is a list of the new hardware: mobo- http://www.newegg.com/product/product.asp?item=N82E16813128321 processor- http://www.newegg.com/product/product.asp?item=N82E16819103029 video card- http://www.newegg.com/Product/Product.asp?Item=N82E16814141034 ram-http://www.newegg.com/product/product.asp?item=N82E16820161067 so this is what is going on. when you boot the pc a goes through some stuff and then stops at a screen that says : PXE-E61: Media test failure, check cable PXE-M0F: Nvidia boot agent Disk Boot failure, insert system disk and press enter why is my video card failing? and my disk boot too?
