Tip

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.

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.

NMI:parity check /memory parity error


In my experience, you get a memory parity error when one of your memory sticks has gone bad.
I don't know how many sticks of memory you have or what size they are, but you can try removing one and see if the error goes away. If not, remove another and try again.

You're probably looking at buying some new memory. If so, use the opportunity to increase your memory within the limits of your operating system.

Win XP, 32 bit, will see up to about 3.2MB of RAM
64 bit can see over that up to about 8MB

Hardware Malfunction


Hi there.
Parity check is usually to do with memory due to dust, take the memory out clean the contacts with a soft, clean dry paintbrush and the slots too free of dust, re-seat the memory and your problem should be solved.
post back if you need any more advice.

Good luck and thanks for using FixYa!!

Hardware malfunction


From the error report, it sounds like you have a bad memory chip (RAM).
If it's under warranty, contact Dell for a replacement.
If it is out of warranty, go to a vendor that sells RAM and replace it (such as www.crucial.com)
