I originally had this problem "I bought a new computer in component form (an abit raid MB, an XP1700+ CPU, 2 x 256mb ddrram) and put it together (i have done this lots of times)when i started up the computer i got no video yet i also got no beeps or anything else apart from the drives and fans all starting up.Another strange thing is to turn the computer off i have to gold the power button down for 5 seconds, the motherboard is one i have used before and is a straight press once to turn off normally."
To try to fault find and see if it was a dodgy motherbord i took the memory and cpu home to tyr there and as soon as i put the memory chips 2x 256mb DDR chips in my computer it did the same thing to my motherboard. Now even putting the old memory back in i can no longer get video and my computer too has changed from 1 push of the power switch to having to press and hold to turn it off
it is unlikely to be cpu as i have had a working one in the computer that does same thing and then works when put back in it's original machine
