I'm troubleshooting a clients computer that does not get a display on power up. The user was turning the computer off and back on until the video finally displayed.
Since the computer was powering on and I did not hear any beep codes and the logs only showed unexpected shutdown (powering on and off). I enabled remote desktop and had the user call me the next time it happened. Sure enough I could remote in the the computer but they had no display. Remote restart typically not resolve it. If I remotely shutdown and the user powers back on it typically did resolve the issue.
This is a dual monitor configuration - 1 DVI (primary) and 1-VGA (secondary) There are no adapters in place. The original on-board was using a display port to DVI adapter. Windows 7 Pro
This configuration has worked fine for about 3 years. This all began about 2 months ago.
