Hey guys, I have an HP pavilion dv2915nr laptop and I broke the screen so I removed that and hooked it up to a spare monitor. Everything was going great until I accidentally knocked out the video cable when I was using the computer and now, every time I turn on the computer, the display shows there's no signal right after the windows loading screen. It'll only work in safe mode or if I uninstall the display adapter driver. I don't really know what happened - I hope I don't have to replace the graphics card or anything. Please help!
