Well, I posted this a few minutes ago explaining everything in detail, but for some reason my post got deleted before google could do a cache of it.
I have 4 LGA socket 775 motherboards, 4 775 processors, and 4 ram sticks. All are different brands, from different venders. On all of them, whenever i hit the psu switch on the power supply (not case) the computer turns on by itself. No video. If I remove ram it has a series of long beeps (again turning on by itself). If I remove the processor it doesn't do anything....
What could be causing this? Is a processor required for the computer to turn on?
Does the beeping indicate the processor is working correctly?
