nothing on monitor

[diablo2]

i got an intel motherboard d815efv, i hooked up a power supply added memory, i know the memory works i took it out from a working computer, hooked up a monitor, i hear the hard drive spin and the chip fan spins but i get just a black screen , nothing on the monitor at all ...
i used the onboard video card, an agp video card and a pci video card and each video card nothing still chowed up on the monitor. i know the cards work and the monitor works...
i dont hear any clicking from the board only the fan going!
only beeps i heard when i left out the memory sticks
i took out the battery for a few seconds then put it back in, still nothing

whats wrong..

Can you test the PSU on another PC? Also make sure nothing is shorting underneath the mobo, like a lost screw under there. Plug in ONLY the bare essentials to get a picture - no hard drive, 1 stick of ram, onboard graphics, monitor, no keyboard or mouse even, and see what happens.

i tried another power supply i know that works... still nothing.

no screws or shorting out, the board is in the box on top of a piece of foam that the motherboard box was in

only tried one stick, PSU and onboard graphics,monitor still nothing on monitor. still nothing

I looked up that board spec so check your modules they should be PC-100 or PC-133, 3.3V only. Maximum system ram allowed is 512MB so if you tossed in 3x256MB this could be one possible reason the system isn't functioning.

Another possibility is the bios is set to init PCI graphics first over AGP so pop in an old PCI video card and get into that bios.

edit: ok you tried 1 stick so what is the spec of the ram you are using.

 

[diablo2]

they are all older sticks, using pc 100 or pc133

took 3 sticks out of a working computer 3 -128 mb sticks pc 100 or pc 133

i tried 3 stciks 128 mbs pc100
i tried 3 sticks 64 mb pc 100
and tried one 64 mb pc100
i tried a pci video card that didnt work

poped in both pci and agp cards

Assuming you connected the pc speaker and there are no beep codes then this is a puzzle, I would find the jumper to clear cmos and then give it another go with just 1 stick of ram and a pci video card, keyboard only and no other devices connected.
