problem with computers VGA port

[stinkyrossignol]

so i had a computer that worked great then i got a awesome new case i transfered everything over and it didn't work so i transfered everything back and now even though it turns on, i turn on my moniter everythings plugged in. I turn on my computer and... nothing complete blackness not even a no signal sign. I know it's not a problem with the moniter because i tested it on another computer. Please help (can provide more information about computer if necessary)

If you have a graphics card did you plug the VGA cable on the graphics card output

Please post the specs of your pc and some more info about the transfer from the first pc to the second one.

General it shouldn't be a problem when you transfer the parts to another case.

 

1) Does the Motherboard give a sign of live?

2) Did u plugged all cable's back in?

3) Have u tried to connect a differen't cable then VGA to your monitor?
