    Hello Ladies and Gents,

    I've been fighting a bit of a pickle, and I believe you have the experience to save my bacon.

    Recently I purchased a new 1070TI to go nicely with a HTC Vive - which is awesome. Until out of the blue the computer reset... Power cut with nothing except a system event error of 41.



    PSU: Stealth Extream 700W

    CPU: I5 6500

    GPU 1070TI

    My first port of call was to stress test the GPU (furmark), no problems everything steady at about 77C.

    Then the CPU using prime95 - again no problems. Chugging along fine all day around 56C.

    I followed that with a duel stress test - prime 95 and furmark. No snags!



    Then I decided to use the Intel tuning stress test utility plus Furmark - and there it was... GPU power in MSI afterburner was spiking up and down about 20% or more - and boom. Power goes.

    Throttling back on CPU and GPU doesn't seem to stop the spikes. Which do affect frame rate in furmark.



    I'm guessing its either my PSU, or my actual power supply from the wall is off.



    I'm guessing some of the experts in here can help, so thank you in advance.

    UPDATE:

    Just in case anyone turns up with the same problem...

    One of the CPU power connectors on the MOBO wasn't seated correctly, so under full load bad things were bound to happen.

    Solved and happy again.
