I just finished a repair on a system with a similar situation. It turned out
to be a bad power supply. In my situation, the tower lights lit up, the fans
all worked, and you could hear the hard drive begin to spin up. I could see
the system begin to boot, as it would show the Bios information, then the
monitor would go blank, and stop the boot progress.

So......  even when it appears that the power supply is good, it may not
have enough power for the system to operate. So, try a new power supply
first, if you can. It is MUCH less to replace than the MotherBoard!!!
