Not sure weather this belongs in the Hardware or Windows 7 section but here goes. I'm having issues with running a dual monitor setup, in that it works fine some of the time but periodically one of the monitors' screen will be blank. This screen briefly flashes the display when turned on but then goes blank. I know it works as it always shows the boot screens, and as such it seems like it could be a driver or resolution issue. I've tried identifying the graphics card as:

It's strange as sometimes it will work perfectly fine, whereas others it will remain blank. Any suggestions are greatly appreciated, and I thank you in advance for your time.
