I have my computer set to dual boot, and it runs ubuntu and win 7. I normally don't shut my computer down, because I use it frequently, so I normally put it on hibernate. When I press the power button, the GRUB loader shows up, and then I can choose windows, and resume windows, or I can start loading ubuntu.

If I have windows on hibernate, will it be using up some of my RAM memory, and cause it to lag? Or will I not have a problem at all?
