Windows 7: My dual monitors go blank at start up menu

My dual monitors go blank at start up menu

I turn of my computer every time I'm not using. When I plugged in my second monitor, it made me use it as a dual monitor right when I plugged it in without any driver installation. After that I turned off my computer to do something else and I left my second monitor plugged in thinking it's going to work again. so I turned on my computer and the second monitor worked till the start up menu, that's when it went blanked. As for the main monitor, it stayed blank, so I unplugged my second monitor and kept my main one and did a restart. I just want to be able the keep the second monitor plugged in without unplugging it every time I want to use it. Besides, the settings are saved. but for some reason when I detect my second monitor it says its not detectable. So basically, my dual monitors go blank when I keep them plugged it and shut down and then if i turn off my computer both monitors go blank but when I only use my main monitor and wait till desktop screen and plug in my second monitor, it works.
