    Default PC shuts off and restarts itself

    Hi There,

    I don’t know if you can help but I am having system stability problems with my home built computer.

    I bought the Asus MB P6X58D-E in 2011 and built a computers and the specs are below:

    Asus MB P6X58D-E
    Intel i7 Extreme edition 3.46ghz processor
    Cooler master 750W PSU
    12 GB crucial 1333mhz 10600 (4gb x 3 sticks)
    NVIDIA Quadro 2000
    750GB WD HDD
    Cooler master V8 cpu heatsink fan
    Cooler master case HAF932

    My system has been running fine since I built it in 2011 but just a month back, it has been acting funny. It shuts down like power cut and a couple seconds later reboots.
    I tried and diagnosed all parts and it seems there no problem with most of the parts:

    - Disconnected the HDD and checked what happens, after a while, it happens again - black out and restarts
    - Removed all RAM sticks and tried another single stick - same results
    - Checked the cpu heatsink fan by fixing another fan on the cpu and reapplying the heatsink gel, same results,
    - updated bios to 0701 version, problem still exists
    - Removed GPU out and switched on the PC, after a while, goes off again,
    - Gave my computer to a technician, and he says the MoBo is faulty.

    What I don’t understand it, I did not change anything, nor installed any new hardware.. It was just another normal day when I powered on the PC, after about 30 minutes, BOOM, power out and restart again.

    I would really like to know what would be the problem?

    Appreciate any help from you

    Either the motherboard or PSU has failed.
    No wonder it doesn't work! You installed the coils backwards

    Main PC: Core i7 3770K 3.5GHz, Gigabyte GA-Z77M-D3H-MVP, 8GB Kingston HyperX DDR3 1600, 240GB Intel 335 Series SSD, 750GB WD HDD, Sony Optiarc DVD RW, Palit nVidia GTX660 Ti, CoolerMaster N200 Case, Delta DPS-600MB 600W PSU, Hauppauge TV Tuner, Windows 7 Home Premium.

    Which exact model of PSU is it? It's possible it's the PSU, but my bet is tending more towards the motherboard.
    Intel i7-2600k with an XSPC Raystorm water block, 4x4GB Corsair Dominator, SLi Evga-GTX560Ti-448 FTWs, Asrock Extreme4 Gen3, Crucial M4 256GB SSD, Samsung Spinpoint F3 1TB HDD, powered by a Silverstone Strider+ 850 PSU in a Silverstone TJ-07BW case.
    I'm not buying EK GPU blocks ever again. (One GPU killed)
