Alright so yesterday my graphics card died in the computer I built myself. I figured that it'd be an easy enough fix. I went out and got a Radeon HD 5770 to replace the dead card (a GeForce GTX 275). I took the old card out and put the new one in fine and when I turned the system on, the fan was spinning on the graphics card. However, when I looked at my monitor I was getting a "no signal" message. I tried another cord and it was still saying "no signal." I've researched this and I've seen two things: 1. Potential driver conflicts because I never uninstalled the old drivers and 2. Something about disabling my onboard graphs. Neither of these are helpful to me though because my monitor isn't even registering my computer. If anyone has any advice please let me know, this is so frustrating because it seemed like an easy fix. I also tried another monitor. When I turn the monitor on it says "D-sub...power saving mode" then goes blank. It's able to confirm which port the cord is plugged into, but for some reason can't get any picture. Any suggestions? Thanks!
