    Hi everyone. I'm hoping someone here has some ideas on what's going on with my PC because I'm out of them. :(

    Recently my system has begun to randomly shut down while gaming - no BSOD, no Event Logs in Windows other than the kernal lost power. I've replaced the power supply (1050W), the motherboard, the video card, the sound card, the case, the CPU and the CPU cooler (moved from air to liquid cooling) and even my UPS. Nothing has helped. I've run CPU diagnostics - the Intel Processor one turned up nothing, using OCCT and Hot CPU Tester Pro both reproduced the shutdown, but apart from that didn't show anything odd. Memtest86 didn't find anything wrong. I've even tried to turn down the voltage to the CPU in the BIOS to no effect.

    I'm at a total loss at this point. Help! :)

    First Name:
    Is it a particular game ?
    can you remember when it started anything change ?
    Is the internet required to play the game?

    sounds like you replaced a lot of the hardware

    Did you include chipset drivers and re-install the software at all ?

    you never said what PSU U bought--just 1050 watts--
    also doesn't say what RAM U bought---
    studying about the new Haswell E CPUs--
    they have 8 cores & accordingly they have a new temperature ratio , especially when over clocked---
    even thought a 2011 socket CPU Cooler might fit the screw patteren on the new X99 motherboards---
    recommendations are to use one made specifically for the new socket 2011 v3---
    they are brand new on the market so proably not a whole lot to choose from---
    about the PSU---
    Intel says the new Haswell Es CPUs run at 140 watts TDP at idle
    a Ivy Bridge I-7 CPU runs at 80 watts TDP at idle
    so this new CPU / motherboard socket is going to demand a strong PSU on the 12.v rail--
    also reading
    looks like the X99 motherboards shipped before they had all the kinks out of them---
    didn't look at EVGA , but support pages for ASUS says they have kicked out several BIOS updates
    for their X99 line of motherboards

    It's any game I try, 3D, 2D doesn't matter.

    I don't recall, 3-4 weeks ago I think now.

    And yes, after installing the OS chipset drivers, etc. were the first things I put back.

    I've tried Thermaltake (3) of these: Thermaltake Tough Grand Power Supply ATX 1050 PS and am now using a EVGA SuperNOVA 1000 PS ATX12V/EPS12V 80PLUS Platinum Certified Power Supply 220-PS-1000-V1. RAM is 32GB (4GBx8) DDR4/2400MHz Quad Channel Memory (GSKILL Ripjaws 4).

    The 5930K I have only has 6 cores (they come in 4, 6 and 8 core flavors). I'm not overclocking - there's no need to - and I am using a cooler designed for the 2011 v3 socket. Hottest the CPU gets even when I can get a game running for a while is 43C. I've also got the latest BIOS for my motherboard.
