Nvidia code 43 on dell laptop

[animk]

I was on win 7 64bit, my screen died while I was doing nothing, after I rebooted my computer the nvidia properties were gone, I couldn't open nview and it showed that the device was running on standard VGA driver.

Any ideas what's going on? The video card is nvidia fx 3600M on dell precision M6300.
