Hi guys I am trying to power on my new computer build but for some reason it won't boot to the screen? the motherboard light is in, the power supply seems to be working and the tower lights are on. I have a asus m2a mvp motherboard. I tryed to swap out the video card for a regular pci card and picture still doesn't show. now i am also running a amd phenom cpu. could this be the problem??? it does say that i need to reflash the bios but do i have to put another cpu in to do that? please help!!what are ways that i could tell if the motherboard is just dead?
