Windows 7 computer randomly blue screens

I have been having trouble with my computer randomly blue screening over the past couple of months, and I would appreciate some help with it. I have replaced almost every part of the computer, but it is still having problems. Everything is running at stock speeds and settings, nothing is overclocked. Temps are good, nothing is overheating. At first the computer only blue screened when it wasn't being used, but now it happens while the computer is in use as well. Any help is appreciated!

My current specs are as follows:
Windows 7 Home Premium 64 bit, with Service Pack 1
i7-2600K @ 3.4GHz
8 GB of Corsair Vengeance (New)
Gigabyte Z68X-UD3H-B3 (New)
Seasonic 850W 80 PLUS Gold (New)
OCZ Vertex 3 120 GB SSD (New) Primary HDD
2x EVGA 560 in SLI (New)
Antec DF-85 Case (New)

  1. Did you run a memory test, that is the most common hardware cause of random BSODs in my experience.
  2. It was happening with my previous memory as well, but I have not tested this memory yet. In the Event Viewer, the Critical error showing up is something related to Kernel-Power, with the event id of 41.
  3. Few reasons... Mainly hardware related...

    - Since your are using 2 EVGA 560 in SLI, your PSU might not deliver or compensate
    the sudden power needs of your two video cards specially if you are playing games
    or, using multi threaded CPU and GPU applications. Although your PSU's power
    output is more than enough for the current spec you have, sometimes PSU
    manufacturers cant made their products perform the same in all models, in addition
    to this are factory defects on capacitors or defects of the processor due to improper
    shipping practices made by parcel service staff particularly if you bought your PSU
    online.

    - RAM defects due to improper shipping (again) if you bought your RAM online.
    A defective ram can cause BSODs and random starts, sometimes this affects
    your hard drive's boot records that leads to corrupted OS that will need
    reinstalling.

    - Mobo factory defects or defects caused by improper handling while in the process
    of shipping (again). Motherboard chips are sensitive to strong vibration or sudden
    impact on hard surfaces like floors or hard thick boxes, they get damage easily
    specially if your mobo was dropped or thrown around by parcel service staff while in
    the process of delivery. This also applies to your hard drive and other components.

    - Wrong motherboard / RAM configuration or settings.
    Some users who are not familiar or not knowledgeable in overclocking, what they do
    when they assemble their new PC, first they set their mobo's settings to default on
    the very fist bios start up in order for their system not to cause any problems while
    installing their favorite OS, that makes their system function based on
    manufacturers settings (AUTO in majority) thus, whenever their mobo detected
    that a hardware installed needs additional power in order to function properly it will
    automatically compensate and draw power to it and adjust the necessary
    voltages it needs. For those who are a bit knowledgeable in overclocking, they
    tweak their mobo's settings based from default setting, that ensures they are only
    changing the parameters they needed in order to properly overclock their system
    and leaving their other parameters to default.


    -- Hope this helps, god bless and advance happy new year! :-)
