I've looked all over the place for an answer to this, and none of the things I've found have seemed to fit my situation.
I have a brand new Dell laptop with Windows 7 64-bit. The problem I'm having is I'm continually experiencing a sudden momentary cut-out of the display followed by a sound from my DVD drive, and each of these occurrences is accompanied by Event ID 9009
in the event log. The source/provider name is Desktop Window Manager
and the message is "The Desktop Window Manager has exited with code" followed by a random hexadecimal number in parentheses.
From what I understand, the "Desktop Window Manager" is what controls Aero among other things, and the issue I have could be related to my video driver. I'm sure my video driver is up to date -- I've checked a number of times. The video card is NVIDIA Quadro K1100M.
If anyone has a solution to this, I'd be grateful.
