    NMI:Parity Check/Memory Parity Error

    This is for my work pc. When I try to shut it down it gives me the following error.
    Hardware Malfunction
    NMI:Parity Check/Memory Parity Error
    The system has halted

    It works fine otherwise. Just when I try to shut it down.

    Great link. I'll replace the memory and see if that helps any.

    If the memory isn't ECC, then it can't generate "parity" errors anyway. In that case, it'll rather be an I/O problem, e.g. on PCI or (remains of) ISA.

    Thumbs up Solution to NMI: Parity Check / Memory Parity Error

    Symptoms I had:
    1) screen showed a choppy image
    2) computer froze
    3) freezing was completely random, but during operation, not boot up
    4) my VGN-FZ190 laptop heated up hotter than the sun all the time (I thought it was going to be recalled)


    Solution:
    1) Clean your laptop! That's it. No magic. No cost.
    I brought it to the Sony store in the Burlington, MA mall and female tech said she saw it once before and because the screen froze it must be the sound card. My sound card is attached to the mother board so I had to send it to San Diego and pay $700 for a new one. I told her I thought the overheating caused warping and other malfunctions but she didn't buy it. I'm an engineer and I thought I would try to fix it before trusting her idea. By chance because I told her it was overheating she blew an air can into the vents and blew out a ton of dust.

    I decided to take it home, completely dismantle it, push every wire into its socket and tighten every screw and clean all dust from it. I did all this and it has miraculously fixed the problem and it is no longer overheating or getting a parity error. Morale: Don't trust a tech. Trust your instincts first. I also saved $700. By the way. I'm a real jedi.

    Solution To: 'NMI: Parity Check / Parity Error'

    Master Jedi is right.

    I had the same problem whilst playing Eve Online. I thought it was the heavy demand on my gfx card, as it only seemed to happen while playing Eve.

    I tried updating my bios, gfx card driver, etc. But to no avail...

    Then I dismantled my tower, and discovered that the air intakes for the cpu, and gfx card cooling systems were totally clogged with thick dust - I leave my computer on 24/7, so you can imagine it's just hoovering dust all the time - I cleaned it all out, and it's as good as new!!

    Needless to say, I always turn it off when I'm not using it now.

    Hope this helps.

    Smile SOLUTION

    I HAD THE SAME PROBLEM ON A DELL OPTIPLEX 330 DESKTOP. THE SOLUTION WAS TO TURN OF THE ONBOARD ETHERNET CARD AND THE PROBLEM WENT AWAY.

    Talking Fixed for me

    I had the green leds 1 2 3 lighten on my dell optiplex 755, so something was wrong... I removed everything, and of course it was the lst element I removed that was causing the "parity check" problem. my firewire card was dead ! as soon as I removed it, the green leds disappeared and everything went back in order...

    good luck for anybody having this issue. if you keep on searching, you'll find the solution
