I have DELL Precision 650 Workstation, and when I turn it on it starts up, but shows "no signal" in monitor. The monitor LED becomes green for 5 seconds and then goes yellow. I have tried to change the video card from another Dell Precision 650, changed the cables, monitors, and even processor, but still couldn't resolve the problem. Could someone help me out with this issue?
I would appreciate any help.
Thank you in advance.
