New monitor not working

[DeathMetalGamer]

uhh this is a slight problem I bought a new flat screen monitor LCD 19". for my cousin, when we plugged it in to the video card it came up for a few seconds then went out... every time we start it the same thing happens. The computer is an old E.machine that came with a PCI express card. please help I guessing that the card doesn't support LCD but i don't know and don't want to waste more money

What outputs are on the video card?

What inputs are on the monitor?

And which have you tried so far?

As far as I know all computers support LCDs.

1.  Does the video card work with another monitor (e.g. an "old" CRT)?  Or conversely, does the LCD monitor work on another computer system?

2.  Display went out...
     a.  What came up on the screen?
     b.  How far did the startup/boot process get before it "went out"?  Basically what sequence of screens did it go through?
     c.  Define "went out".
         (1)  Did the monitor screen go "black"?
         (2)  Is there anything left on the screen, e.g. a "blinking" cursor?
         (3)  Is the monitor still powered up?
         (4)  Is there a power/status LED on the monitor?
         (5)  If yes, what's the state:  on/off, blinking/steady, color (green/orange/yellow)?
