I built the computer below a few months ago and it has been working fine (except for a screen freeze every now and then). A few days ago the screen suddenly went black. I cannot see anything, including boot-up screen or BIOS. I have tried a different monitor, HD, cables, I have tried to boot from the CD/DVD and nothing happens. All the fans are running and HD is spinning, just can't get a signal to the monitor.
