We have Dell T1650 PCs with 2 nVidia graphic adapters / Windows 7 and 4 attached monitors.

At initial start all screens are blank, the computer does not show anything. If powered off by pressing the hardware power button and then restarting all monitors show a picture. The Windows event log shows only the errors, that the machine was shut down unexpectedly.

The last entry with blank screen seems to be that user specific dlls for every application are loaded.

How can I find out the real problem?
