DARK SCREEN SONY VAIO VGN-NW150J

Yea, should not have a problem, but i do believe you will need to get the Nvidia drivers for windows 7. However, that should not be the case, when i did an upgrade I didn't need the drivers, I got them any way, so I will recommend to go to Nvidia website and get the drivers for the video card you have.

Generally, if a mouse button quits working, it requires the replacement of the touchpad assembly.
Boot to the safe mode, see if the button works there, if it doesn't, then it is a failure of the switch in the button

if the function key of your keyboard not working, the primary reason is the chipset driver of your mainboard not installed. you need to load your cd/dvd driver to your cd/dvd rom then you can find the list of drivers and select the chipset driver click it and follow screen instruction after installation restart and done. be sure to locate the chipset driver base of your OS.
