E machine wont recognize the moniter or key...

With the limited info that you provided, it seems like the motherboard is not functioning. When you turn the computer on, does anything happen in the box?

If you motherboard hasintegrated video and using video card separately onboard won't work and dont plug in it, Please provide more detail if you can ex. motherboard manufacturer. keyboard and monitor has no problem, you may using USB inputs and they are desabled in BIOS, Was it warking earlier?

You've tried different monitors/keyboards with this computer? Is the monitor's connection right on the motherboard (i.e., it's probably next to the USB ports, etc.)? You can try using a different video card, just to make sure your monitor is working.

How do you know the keyboard isn't working if your monitor isn't working, either? The motherboard may just not be working at all if it won't let you toggle the caps lock/scroll lock keys. Usually if it boots but won't recognize the keyboard, the PC speaker will beep at you and the monitor will say something useful, like "Keyboard not recognized, replace and press F1 to continue."

A little more information would really help on this one.
