crash - Scary computer crashes (picture attached)

    Since the purchase of my laptop (Asus N56vz) I have been experiencing random crashes. For many months I have tried to solve the problem myself but to no avail. So I give you all that I know and maybe you know the reason or can point me in a direction.

    I THINK the crashes might be related to the nVidia card, as they occur only when the computer is under a big load graphically (video games, full-screen YouTube etc.). At first i thought that was something related to a corrupt RAM, so I tried removing one RAM stick and the crashes actually became way less frequent. But that probably was just a coincidence.

    And the crash itself looks like this:
    enter image description here

    The distortions are either red-ish or green-ish and as you can notice there are stripes from the bottom of the image that are drawn in the middle. The screen freezes like this (or similar) and the last few milliseconds of sound that was playing is looped over and over again out of the current audio device, creating a kinda buzzy, scary sound. The laptop doesn't react to anything - only solution is removing the battery or long-pressing the shutdown key.

    I hope some of you might recognize sometething in this and point me in the right direction for a solution. Thanks!

    EDIT:

    Some more things I failed to previously mention that I have done:

    • various memory tests (both Windows and Linux ones)
    • chkdisk
    • updating drivers (GeForce Experience keeps them nicely updated)

    cpu - Computer crashes
  • kelton52

    I just installed a new motherboard, cpu, ram, and a psu. I am having problems because my computer will randomly crash(restart) and I can't seem to associate it with any specific thing that I'm doing or the computer is doing. I noticed that when I first put it together I couldn't run an os or anything until I increased my ram voltage to 1.8v. I don't know if I should increase the voltage, or maybe adjust the timing(I don't know hardly anything about that). I also notice that my mouse that I just purchased seems to randomly not be recognized by the system.

    I also tried disabling my onboard audio, and that didn't help.

    ALso, I've updated my mobo bios to the latest firmware, and updated windows 7 all the way.

    Here's my specs

    OS: Windows 7 64x

    cpu-z http://valid.canardpc.com/show_oc.php?id=1334765

    ram: W2000UA1GP

    Update

    Alright well, I backed off the multiplier to slow the cpu to 2.8ghz but I'm still experience the same problems, and the same cpu temps...I hover around 40c for the mobo and the processor

    You can't associate it with anything specific? I can. That machine is overclocked and probably has insufficient cooling. Some motherboards have a feature that will automatically power off the machine if it reaches a certain temperature, I believe Intel calls them "thermal events", not sure if AMD uses different terminology. You can adjust thermal alarm settings in the BIOS as well but I'd suggest assessing the issue properly rather than bypassing it to avoid trashing your hardware.

    The stock for that chip is 2.8Ghz. You are running it at over 3.5Ghz. Put it back to stock and you will notice a much more stable system. Your CPU will thank you (and probably last longer). The easiest way to achieve this is to go into the BIOS and return it to setup defaults (usually one of the function keys will do this). I wouldn't recommend overclocking unless you know what you're doing.

    Basically on default auto settings the board would overclock the cpu, so I had to set everything manually and it works fine.
