Will a mobo boot without ram? / How to test a mobo?

[foges]

Question 1:
Will a motherboard boot up to at least the POST screen when ram is NOT present?

Q2:
Will a motherboard boot up to at least the POST screen when the CPU is not present?

Q3:
I have 3 seemingly broken motherboards. All of them do the exact same:

Start the CPU and PSU fan when the power button is pressed. I however get no video output from the video card. I tried two video cards.

I deffenetally know that the video cards/PSU/Monitor work.

Is there anything that might revive the motherboards? or something i havnt thought of?

Make sure in the motherboard bios you have the video source pointing to the correct location (AGP, PCI, PCI-E or Onboard).

I just had the same problem. In my case, it was the ram..

Try clearing the CMOS

I dont know what setup you are using to test but also try unplugging all peripherals from the motherboard and see where that gets you. Also if you have a USB keyboard/mouse run through an adaptor for PS/2, just run it on USB. Took me forever to find this problem on my computer. But otherwise the main culprit would be RAM(do the one stick at a time test) or CPU. Anyways give that all a try!
