Windows 7: Extended Desktop Keeps Reverting Back to Cloned Desktop

Hi everyone. I'm having a problem in Windows 7 with my dual monitor setup. Being a student, my laptop comes with me during the day to classes, but when I return to my desk, I have a dual monitor setup through a docking station. I haven't had a problem getting the displays to actually output in extended desktop. Instead, I can't keep them set that way. Installing any program, opening the system task monitor, letting the computer idle into sleep, or any process that makes the screen "flash" sets the screens back to clone. It's even more annoying that for some reason, I cannot get the system to recognize the external monitor through the display settings. To get around this, I've set up schemes that I default to through the Intel Graphics card. I know it's a minor irritation, but somehow I managed to bypass that default in Vista Ultimate and can't quite figure out how to do it in 7.



I attempted to fill out my system specs in my profile as best as possible, but please let me know if any information more is needed from me. I apologize if anything is missing, this is my first post. Thanks for your help!

have you tried re-installing the graphics drivers?

Yes, I have. To no avail unfortunately. It makes me think that there is some setting in Windows 7 that has the monitors default to cloned (especially since that is what they default to when I initially connect them). The graphics drivers are applying my settings correctly, I just cannot seem to make them stay until I choose to change them.
