I am having trouble installing new PCI Card.

I followed instruction installing a new PCI Card, I even disabled my onboard video card. After installation computer wont boot. A black screen with three colored bars appears and it says 1. monitor working 2. test pc and I forgot the third, but keyboard won't do anything. Please help.
 
If you have onboard video you may have to change a setting in the BIOS or a jumper on the motherboard. The BIOS needs to be changed from AGP to PCI. What kind of computer is it?
 
I figured it out. I didnt connect the monitor to the new card. I'm an *****. It works fine now. Games are running alot faster, however; my desktop looks a little odd. Everything is a little bigger.
