    This thing is seriously bugging me, micro stutters everytime it happened, how do i find out what process is causing this issue? Is it driver? application? or just bios problem? Or is it optimus went bad?
    this doesn't happen during gaming, just idle, all other application is closed and there''s only afterburner and gpu z running.
    Alienware 17 R3, with 6700hq, GTX 970m, 8GB of ram, OS installed on kingston 128gb m.2 ssd and 1TB HDD as storage drive.

    help? anyone?
    Edit: Tried using different versions of drivers, 353.30, 359.00 and the latest 359.06 doesn't fix the issue, even flashed the vbios mod by Prema, it doesn't work too.
    The the reading is consistently spiking to 0 for only an instance from 405 mhz at random intervals, during the spike, the temp reading and the memory clock of the GPU will also spike to 0 for only an instance. But according to CPU-Z, the core clock keeps fluctuating between 405mhz, 135 mhz and then 0 mhz constantly

    Well when idle your lappy should be using the integrated GPU all the time, the fact that it's showing GPU load at all indicates something to do with optimus imo.

    What i suggest you do is to go to nvidia control panel and set the intel gpu as default, then assign the Nvidia gpu indiviually to each application that you want to use the nvidia card with.
