Specs: Windows XP
My computer has integrated video.It's a Pentium3 custom build with Windows XP Pro, and it ran great. I installed an AGP graphics card i had, and when I booted up, Windows starts fine(i'm guessing it is, because it goes thru the startup the same as always-checks cd first, then hard drive comes on,etc.)The trouble is, it didn't "see" my monitor anymore. Nothing appears on it. I unhooked it and tried it on my other computer, works fine. So I took the AGP card out and rehooked the monitor up to the integrated graphics connection(which worked fine before) and rebooted. Same result, Windows "seems" to start normally, just nothing appears on the monitor. It just sits there with the green light blinking like it does before you startup Windows. Seems like the computer doesn't see the monitor?!?

We know nothing about your system specs. May be your psu can't handle the graphic card. What is your psu specs +3.3v,+5v,+12v.
