You might have problems... I googled this and found,
On any PC a forced shutdown can (not always) corrupt the file system.
Was this the NVidia optional update that caused this ?
No good to you now, but this is where a program such as Acronis TI is so useful.
A reinstall may be required to fix this. Laptops usually have a hidden partition that you can access at boot to reinstall to as it was on day one.
