What changed? I read the motherboard changed but since the old "change the motherboard and Windows is whacked out" discussions are so many you wouldn't be trying to use the OS that was on some HDD that was for the old motherboard. Or would you?
If so, I bow out but ask you to google "How to change motherboard and save Windows 7 Operating System."

Dell Studio XPS 8000 2.80 Ghz, 8 GB RAM, Windows 7, 64-bit, nvidia GT Geforce 240 video card, DVI-D single link cable. Monitor shows, "no signal" after windows logo appeared. Changed motherboard, placed Nvidia GT Geforce 610 2 GB. Same result. "No signal." Used VGA cable and it worked, but resolution became soft and colors are shallow. Good enough. However, I used the DVI cable again and I reversed the DVI cable male ends and the screen resolution looked like its in safe mode, but its not. The only option for me to use is up to 1024x768 instead of 1920x1080. The 64-bit option is gone as well. Only 1024x768 and 32 bit color depth is showing on the screen right now. Drivers are updated for both the monitor and new video card. I' m trying to set it up at 1920x1080 at 64-bit. Help.
