The new card is trying to hold some resource that another part is trying to grab - since it's not even booting up it's probably grabbing the resources of the video subsystem (video card most often) if the screen doesn't come up right after you turn it on OR the it's grabbing the resources for the hard drive controller (which would stop boot of OP System.) You should take the new card out, close the computer, start it up, record the present settings (you can find in control panel in any windows after windows 95) and if you can change the video card to an empty number try that. Restart computer to be sure it worked. Shut it down, insert sound card. Boot up. If that doesn't work, see if you can change where the hard drive controller points to; close it, restart. If it works, close and turn off, reinstall new sound card.
If you can change the sound card now to something different than video or hard driver controllers old numbers, do so. Now change the video back (if it was changed) or revert the hard drive controller. Restart.

The power supply is what provides power for everything in your computer (processor, disk drives, hard drives, fans, etc.). If your power supply fails your computer can't turn on at all (no activity). The VGA card is your graphics card. If the VGA card fails your computer will still turn on but you won't see anything on your monitor (no graphics). The processor fan is the fan that sits on top and cools your main processor. If your processor fan fails and the computer continues to stay on it's likely that you processor will overheat and be ruined. If your main processor is fried your computer will turn on but windows will not boot up and you may see an error message on the screen.
If your computer has a sound card there is no need to purchase a new one.
The purpose of a sound card on a computer is for sound to be output through speakers or headphones. The sound card works by converting digital data to sound.
Yes
There sometimes are "Wake on LAN" parameters that can be set in BIOS which will boot a connected computer if the LAN card receives a command.
