I have Alienware 17 with Nvidia Gtx 760M
Windows 8

Today on startup the os hung and after forcefully restarting the system crashed and I got blue screen of death with error message "DRIVER_POWER_STATE_FAILURE"
the system rebooted itself and I noticed that Nvidia was gone. Literally. Everything had disappeared.
I tried to open Nvidia Control panel through control panel but no avail
After checking device manager; under display adapters only Intel was mentioned. Nvidia was under hidden devices and it was greyed out. Under properties it said "driver not connected error 45" the only solution was to reconnect the driver...

I ran bios and under discrete graphics card it mentioned "not detected"

After going through everything on google I wasn't able to find the solution and the only thing which was popping in my mind was that my graphics card is dead. And it only 2 years old.

I reflashed and tried Fn + f5 or f7 but that didn't work and even bios update didn't work.

Then I ran WhoCrashed and the analysis mentioned:
Module that caused the crash: ntoskrnl.exe (nt+0x5A140)
File path: C:\\WINDOWS\\system32\ntoskrnl.exe
Description: NTKernel System
Driver is inconsistent and a potential software driver bug not related to hardware.

I'll cut to the point after searching everywhere I wasn't able to find the solution but my technician helped me I'm just posting here so others having this error can try this and it'll probably help.

 
Solution
Recover your windows before the crash (trust me I tried everything)
After its complete it might load up a black screen with cursor (don't panic it's probably bc it's a driver error)
Just try starting in safe mode and check in device manager if your card under display adapters is showing or not.
If it's showing then everything is fine and it was a driver issue. If not then your graphics card is most probably dead (sorry)
Then after this I just restarted again and my desktop loaded normally.

I hope this will help someone.
