This started happening to both video cards at the same time? Did you recently install software / device drivers that might have caused this? Is there something you did to both of them recently (i.e. ran Windows Update) ??

Can you get a screen if you start up in safe mode? If so you could be looking at a corrupted driver, as safe mode loads the generic/stock vga.sys driver instead of your card's driver.
Speaking of what you can't display, is it just GUI mode that isn't working, or do the monitors not display anything at all?

He cannot even see the bios screen so drivers is out of the question. Is your PC booting up with no screen. Clue* hard drive LED lights up, or if you got speakers you might hear windows annoying music when you boot up.

I have read about updating bios and info from the device viewer, but I am unable to see what I am doing.
I could be wrong, but I didn't take that to explicitly mean that he couldn't even see the BIOS info on the screen.

Sure you haven't adjusted the monitor brightness down all the way to black? Might sound silly, but I've seen sillier things happen.
Do either of these systems work with a different monitor connected? A different monitor cable? Does the monitor in question work OK on a different PC?
Edit: Sorry, please disregard that - I just reread your question a bit more attentively.
Have you tried using a PCI or AGP add-in display card with them?

I'm thinking it may be time to buy/borrow a PCI video card. Put that in, and see if you can get any boot messages.

Just because the lights are on doesn't mean the computer posted ,do you hear the first beep to indicate it passed the post test ,the beep will come from the internal computer speaker .

This is very true, you should always be able to hear your system beep when booting up. Unless the system speaker is broken or disconnected.
