My girlfriend gave me a call earlier this afternoon saying that whenever she booted into Windows her screen would go blank and flash "No Signal". I figured "Ok, the refresh rate probably got changed" so sent her through the steps to reset it in VGA mode...
Whenever a setting got changed in VGA mode (resolution, bit depth, refresh rate) the screen would go blank and flash "No Signal" again.
I assumed this must be a driver problem, so I uninstalled/reinstalled the current nVidia drivers and had no luck - then I went on to try the newest beta drivers, same problem!
At this point I was beginning to think it was just the card, but I decided I should swap out the monitor with another to see if there was a problem on that end... but it seemed unlikely.
Lo and behold, I restart with the new monitor and everything works perfectly! The monitor is detected, I can set any resolution and any bit depth... Once this is setup I decide to swap back to the original monitor - it works.
I figure everything must be working now, so I restart to test it - Same problem all over again!
Finally after about 15 restarts and monitor swaps Windows finally picks up the original monitor as "Daewoo HL711S" instead of "(Default Monitor)" and now everything works fine, through restarts and all...
Does anyone have any even remote idea how this happened? It was working fine for a week (new video card, early christmas present for her, 6600gt) then strangely stopped working this afternoon, and then started working again as described above!
