yeah, I put together a ECS K7VZA Rev 3.0 KT133A Chipset Motherboard and a oem 1 ghz 200 fsb athlon and pc 133 kingston value ram. Got everything from newegg. Turn the power on and nothing happens. My fan won't even go. I tried a working fan so thats not the problem.. My ram works.. so is it the oem cpu or retail motherboard. Help thanks!
