No Display on Monitor

[Slannman33]

I'm getting no display from either my graphics card DVI slots or from the one built into my mobo.
My monitor either cycles between analog and DVI channels and then sleeps or doesn't wake up at all when plugged in.

I have tried with another monitor and that got no display either.
Really strange as my PC was working fine yesterday and now I can't use it!

Any help would be appreciated.

Have you tried resetting your CMOS? I've fixed errors similar to that just by resetting the CMOS and it magically works. I think it's because when the board queues up what devices to load in what order it gets corrupted somehow; mostly because of the strange nature of CMOS in my opinion.

What's cable you using?

Is your computer attempting to boot or Posting?
