I am trying to build this rig for a friend, and the Mobo and CPU are supposed to be good.
It's an ASUS P5W DH Deluxe, and an Intel 641 (775 socket).

I have tried two video cards, and those are known to be working. My Antec Earthwatts 500W PSU is fine.

I don't get anything on the LCD, no signal at all. I don't get any beeps from the mobo, but a steady green LCD on the mobo itself.

Asus tech support says I may need to flash the bios or replace the bios chip. I don't know where to get the bios replaced, or know how to flash it if I can't get to POST.

Any recommendations? Again, this was supposed to be a very affordable PC for a friend, not for gaming, just email, web, and Office type products.

I also pulled 3 of the 4 512MB memory chips.

Thank you.

Might be this: There are three P4 641, two of them *revision B1 an C1) don't work with an older BIOS, it needs to be 2103 or above.

But in order to update the BIOS you need a CPU that's working on the mobo.

Thank you for your reply.

I have a 775 computer that works, so I hesitantly started swapping parts.

CPU change didn't work, but apparently the memory is bad, as I put my good OCZ module in and it fired up.

BTW, the CPU's get warm very quickly.
