When it boots up the boot info is ALL BIGGER than normal too....like when you first start with new graphics card drivers.
This would be a problem with the card or the mobo, or a BIOS setting maybe.
This is not a driver or win7 problem. Win7 and drivers aren't even started yet at this point.
This could also be the monitor, try playing with it's settings or replace to find out.
Then replace the card and see if the issue resides.
