Hi! ericw616, welcome to 7F
Do you still have the 7 OS on the system? we'd need to know the model, Starter, basic, Home Home Premium, pro, ultimate?
How serviceable is the notebook? Does it run pretty well?
Did you save back-ups?
If you haven't done too much with it you might be able to recover some files by using a file recovery app like PhotoRec - CGSecurity
To get some information back. I wouldn't use those files, but it might give you enough info to jog your memory to where you could remember the right driver, and then you could go back and re-download it to re-install.
The driver page for your NV78: Downloads & Support Documents - Notebook / NV Series / NV78
Intel's site, but there again you would need to know the make of OS to match up the proper drivers: http://downloadcenter.intel.com/Sear....aspx?lang=eng
You could use this to identify your chipset : Intel Chipset Identification Utility - 3.05 Download - EXTREME Overclocking
