I cannot find the problem and it's baffling me completely. Here's the deal:
I have 4 pc's and they're all doing the same thing, so it's definately something I'M DOING wrong.
Main Problem: The monitor doesn't turn on, indicating that the pc is not booting, right?
The monitor works, and i've tried a different monitor just in case it's not compatible or something.
I've tested and tried another Power Supply - nothing
I've tested and tried other Memory - nothing
I've tested and tried another Processor - nothing
I've tested and tried another Graphics Card - nothing
I even tried a different MOTHERBOARD that had built in graphics.. nothing!
I've taken EVERYTHING out of the machine... one by one... still nothing

Is there a specific jumper setting that i'm missing here or something

I've got this problem with TWO P4's (Gigabyte Springdale motherboard GA8IPE775-G) and (Prescott 533 P4145GV Rev. 5.01)
same thing with my P3's and P2's - Asus motherboards A7V133-C and a Matsonic

Hence, my conclusion that it has got to be a setting (*jumper or other) that i am not checking on these boards.

Any suggestions / help would be appreciated - or info on where i can download any specific settings for these motherboards - thanks man!
