BSOD caused by Geforce GT555m - nvkflt.sys

Hi there,

A month after getting my new Dell laptop (and a few days after playing GTA IV in high graphics settings), my laptop started with odd explorer crashes and BSOD crashes. This only ever happens when the Nvidia Geforce GT555m is enabled, so if I disable it, no problems.

I've checked the minidump (see attached) of the BSOD and it's caused by nvkflt.sys (which is an NVIDIA driver), so that would make sense. I've uninstalled and (clean) reinstalled a variety of NVIDIA drivers and none of it fixes it.

Any ideas? I thought the most obvious is the graphics card is cooked, but I can get away with 1-2 hours of playing (for example) Skyrim in very high settings completely smoothly before I get the BSOD, so surely it can't manage that if it's cooked??

System specs:

Dell XPS 17 (L702X)
Intel Core i7-2630QM
6GB RAM
NVIDIA GT555m 3GB
Intel HD3000 (1.5GB shared)
Windows 7 Home Premium 64-Bit

It may be heat (download cpu-z and gpu-z) or power.

The DRIVER_POWER_STATE_FAILURE bug check has a value of 0x0000009F. This bug check indicates that the driver is in an inconsistent or invalid power state.
