i just recently upgraded my memory on my gateway m 1617 to run a 64bit operating system. I installed windows 7 home premium and everything works great until i wake my computer from sleep mode, after i wake it up it has a X over the volume controls in the toolbar and when i get menus that pop up asking for permission to do something i see white lines across my screen. I've run the windows 7 upgrade advisor multiple times and it says that my computer is okay to run 64 bit. Everything else works fine after waking my computer up its just the sound and the display problems. Can anyone help me out on this one?
