My mother has an HP p6604y computer and the integrated graphics card died. I replaced the motherboard with the new motherboard, which is exactly the same as the old one. The motherboard is an Alvorix RS880-uATX with part number 620887-001

I installed the new motherboard. When I turn on the computer, it displays information about the BIOS but it doesn't seem like the BIOS is posting. Eventually it just goes to a black screen. What do I have to do? I still have Windows 7 installed on the hard drive and I didn't change anything besides the motherboard.
