When I power up the HP m8457c desktop computer the monitor displays the error message "no communication from computer" and goes into a sleep mode.


This is telling you you have no video signal. Now you need to figure out just what the problem is. Could be the video card or any other piece of hardware in your computer. My bet goes with video card or power supply. Unhook the other stuff and try to boot with a "bare bones" system--that is, using only your video card, CPU, and memory. If you get video, try hooking up the other stuff until you find the bad part.

U need to check that the power supply and power switch is working.
If everything is working properly, suspect no video output send to monitor resulting the monitor is in sleep mode. U can try switch to integrated display of clear CMOS.

Added a new video card, now my monitor stays in sleep mode


If the computer originally had integrated video, have you tried reconnecting the monitor to that output? Most system boards will automatically detect when you install a separate video card, but on some you need to disable the built-in video in the BIOS before the new card will work. Also, have you considered the chance you just got a lemon of a new card? It happens sometimes (it's happened to me!).
