I have a Compaq Presario Media Center SR2013WM Desktop PC and I was reinstalling window xp and found Bios update at the HP website and updated that also. Rebooted the computer and never saw the desktop again and will not even show the Bios window. I have reset the bios, unhocked just about everything there was , leaving only one memory stick and changing memory in different slots. And still no bios window, no desktop,I can see the hard drive light comes on, the yellow light flashing so the hard drive must be working. The video is onboard and the motherboard is a ASUS A8M2N-LA
