    Am I correct when I say a BSOD is usually the result of bad memory, HDD or a combination of the two?

    What else can cause a BSOD?

    Yep, hardware is one.
    Driver issues
    Software conflicts (when they screw with the WMI-just had that one)

    A bad OC, basically any hardware component, poor device drivers.

    RAM, HDD, CPU overclocked too far. PSU not delivering enough power.

    Software conflicts. Dodgy Drivers.

    Quite a lot can cause BSODs to be honest, just make sure to note down the reason/code the BSOD gives you, and then google it :)

    A BSOD is an error message display. It's when the OS fails to maintain proper operation, protect memory, or even access it. When every piece of hardware, memory page, etc os known to the OS and it can't find it when it needs it, the OS cannot proceed with operation, in order to safeguard data from corruption/bad writes, etc. Next thing to do would be a reboot, so the OS gets back to knowing what's where.

    In my experience its:
    - Unstable OC
    - Bad RAM
    - Bad Driver/ Driver conflict
    - Dodgy Windows Update
    - Wrong BIOS Settings
    - Failing HDD
    - Hardware conflict / BIOS conflict (I have had this!)

    Other than one windows update, Vista has been rock stable for me, I could never get XP like this.
    Have you got a problem with something then? Or is it just a general Q?

    From what I've seen, an insufficient PSU will cause a reboot or hard lockup. A BSOD is a software reboot. Though in fairness, any of the HW things I mentioned above can cause hard lockUps at their extreme.

    Drivers are *usually* the problem. Not hardware.

    However, if you have a working system, and OC it, and then it BSOD, then that is due to the hardware not coping at the new speeds, so is, in effect, now a hardware problem.

    No, I don't have any problems yet :laugh: It's just a general question to satisfy my curiosity.

    Well the only things that have caused blue screens for me is overclocking too high on the CPU and a few small driver software issues. For some reason, Gears of War gave me blue screens randomly but every other game is perfectly fine. Even my CPU is stable. Oh and faulty RAM (only happened to me once).

    Out of curiosity, what is the OSX equilvilent of the BSOD?

    I wish I had time to even see the BSOD, let alone read the thing and copy down what it says. When my machine BSODs, it flashes the blue screen for a split second and the text scrolls up it and then the thing reboots so I never have time to even see the error code. Very frustrating when trying to troubleshoot :banghead:

    you can change bsod screens i changed mine to take a full dump or summit like that so it takes longer but you get a glimps of what it is

    cant remember how i did it but it was on vista and most likely though some setting in the control panel

    IIRC, you can tell it not to reboot on a BSOD, so you can read everything it says. I think its under advanced system settings or something.
