building a fresh PC

asrock 939dual-sata2 mobo
western digital raptor HD
939 amd 3500+
radeon x800gto pcix16 video
kingston valueram 512 x2

when i power up, the cpu,case, and Video card fan all spin, the keyboard lights up,..but i cant get anything out of the monitor, and i hear no beeps.

a friend with pc knowledge told me to disconnect everything but the mobo, ram,video and keyboard and it still wouldnt work.

i have tried resetting the CMOS for 5 mins, also tried removing the battery for 5 mins.

tried known good ram in the same slots, have tried a known good pci card in the regular pci slots to no avail

are there any step by step processes so i could determine what piece of my build is malfunctioning? i am suspecting the motherboard, but the reviews have said this motherboard is bulletproof

any help would be greatly appreciated.

Have you got the separate 12v connector connected?Have you tried all of the RAM slots?
