BSOD ntoskrnl.exe+14e3a0 driver power state failure

I have a sony VAIO laptop model no. SVF15218SNB running on windows 8.1 64bit. I've been constantly getting the BSOD with the error named driver power state failure. I've updated and rechecked all the drivers in the device manager and all of them say up-to-date. When I checked the minidump files of the crash, it said that ntoskrnl.exe+14e3a0 is responsible for the crash.
Here's a link to the dump files
