I just finished my build and was getting ready to start it. I plugged in the monitor and powered on my PC and suddenly the monitor flashed NO VGA INPUT and shut off. I am plugging the monitor into a Radeon HD 7950 with a DVI connection. I can guarantee that the entire PC is operational and its a monitor problem. I have triple checked every connection and there are no bent pins on the connector. I can see the Video Card working so thats not a n issue either. I am going to try some other connections but I just wanted to post this before I did. Please help as I'm so excited to start up my PC and want to as soon as possible. Please help a first time builder!
