    I just put together a pc with the following specs and I have no signal on the monitor when I turn on the pc. I noticed some red led's on the bottom left corner of the mobo that were lit up. Not sure what they mean. Everthing seems to be working fine, all the fans are spinning on everything. The monitor works when I connect it to my laptop. Please help.

    I figured it out. Thanks though. I had to do the first boot with just one stick of ram. Thanks,
