The RAM in the laptop is faulty and needs to be replaced. What you can do is open the bottom where is will be marked (M) for memory or (R) for RAM. It depends on your model you have. (K) is for keyboard removal. Note since you haven't stated which model you have the RAM could be under the keyboard then you would have to remove the keyboard screws on the button.

If this is a newer laptop then the RAM is on the bottom just remove the screws and place those screws on a white paper or better yet in a paper cup. One of the biggest issues I see it a lot of techs loose the screws when they take apart the laptop. This way you know where they are. Also good to mark the paper which screws they are for too.

Now remove the RAM with the power off and the battery out. Take one stick out and try it again. See if you still get that error. If you don't then you know which one is bad and need to be replace. Note most of the newer and prior laptops video memory was shared RAM meaning it used the same RAM on the main system.

Now if you only have one stick of RAM in the system and it's bad then you have solved your problem. Just replace that with the right RAM. If you don't know which one to buy go to the maker of the laptop web site and look up your model by code serial number or service tag number.

10 reasons why PCs crash-You must know tip 2


2 Bad Ram

Ram (random-access memory) problems might bring on the blue screen of death with a message saying Fatal Exception Error. A fatal error indicates a serious hardware problem. Sometimes it may mean a part is damaged and will need replacing.

But a fatal error caused by Ram might be caused by a mismatch of chips. For example, mixing 70-nanosecond (70ns) Ram with 60ns Ram will usually force the computer to run all the Ram at the slower speed. This will often crash the machine if the Ram is overworked.

One way around this problem is to enter the BIOS settings and increase the wait state of the Ram. This can make it more stable. Another way to troubleshoot a suspected Ram problem is to rearrange the Ram chips on the motherboard, or take some of them out. Then try to repeat the circumstances that caused the crash. When handling Ram try not to touch the gold connections, as they can be easily damaged.

Parity error messages also refer to Ram. Modern Ram chips are either parity (ECC) or non parity (non-ECC). It is best not to mix the two types, as this can be a cause of trouble.

EMM386 error messages refer to memory problems but may not be connected to bad Ram. This may be due to free memory problems often linked to old Dos-based programmes.

***Hardware Malfunction*** Call your hardware vendor for support NMI: Parity Check / Memory Parity Error *** The system has halted ***


This seems to be a driver issue likely caused by a new device that needs a driver update.

I was trying to capture footage using Adobe Premiere to a new WD passport and had the same error on a blue screen.

Here is how I fixed the issue (windows vista): Open Control Panel and then open Device manager. From the list, click the plus to expand the category which represents your new device (mine was WD drive management). Go through these drivers and right click and select 'update driver software', then click 'search automatically for updated driver software'. This may take a few minutes. If the driver is updated, you may have fixed the issue, but if not then you will need to go back to the list to try and update another driver until you find the right one.

Hope it works for you as it did for me.

We have a parity error on our ThinkCentre S51 Desktop. What is this and how do we rectify this issue?


A RAM parity error? Just tell it (in the BIOS settings) that you don't have memory with parity installed, or replace the memory with that kind. You probably had to replace the BIOS battery and the setting defaulted to DDR with parity bits somehow.

There's serial communications parity too...mostly deprecated by USB, but it can come up in connecting POS (point of sale) printers, etc.

If the error instead arises in another context; well, you'd need to search for some enlightenment relating to that and 'parity' to get some enlightenment on the subject.

We have an IBM ThinkCentre S51 Desktop PC and the computer froze up with a parity error. We restarted it and we would like to know if that will solve the problem for the future.



Parity error pops up when the memory encounters a read error. It may be a one time glitch or a sign of memory failure to come.

'Parity' is a form of error detection that uses a single bit to represent the odd or even quantities of '1's and '0's in the data. Parity usually consists of one parity bit for each eight bits of data.
On most systems, a parity error detection results in the computer system freezing entirely and the displaying of a 'Parity Error' message on the screen. The system must then be restarted.

I would run a memory diagnostic to see if your memory (RAM) is stable.

Download Windows Memory Diagnostics tool,copy it to a CD and run it. There is a User guide to instruct you how to do this.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response

Thanks, Joe

I'm getting a blue screen on my Dell Optiplex 360 and an error report saying; "NMI:Parity Check/Memory parity error.I've cleaned the computer,scanned the hard disc,but it still pops...


It sounds like a RAM issue. Try downloading memtest 86+ (http://www.memtest.org/) that'll give you an idea as to whether it's the memory or not. If it is, try swapping them out (take out one, take out another, swap ports, etc) to narrow down if it's one or both.
