it may be a permanent damage on your monitor. i think it is unrecoverable.

I think your moniter is messed up and that you should contact the manufacturer to see if it's under warrenty.

3 problems:
1. your monitor but i doubt it
2. vga component in your computer
3. atx component in your computer.

try go to a friend and make some changes. don't buy anything first. just test them to see what's bad.
