The top left corner, type N90 and choose all. Then pick the N90Sc, and when it prompts you for OS, pick Windows 7 64-bit.
Install the newest listings under:
VGA
BIOS Utilities (Make sure its Windows 7)
BIOS (BIOS 205)
After you install (or run) the BIOS Utility, it will prompt you for a file which is the "BIOS 205". Make sure your laptop is plugged in, and run the utility. If it says you already have BIOS 205, do it anyway, it won't hurt to make sure. Often manufacturers have problems with their computers and then make fixes to them afterwards.
Good luck!
I have windows vista ultimate o-o. Do I pick vista or Windows 7?
