Computer operating systems use some pretty basic science. A parity error is the result of corruption in a file. That might be a big problem or a small one. Fixing a parity error will likely eliminate some tiny bit of data, but in most cases will not result in a noticable problem. You should fix parity errors and consider this a good time to think about your file back-up habits. If you back up your files, you will be in good shape if you get file corruption.

Parity is a method of making sure bits have not become corrupted. It can be used in memory and file systems, or any other form of data or transmitted data. The way it works is that the binary bits are separated into ones and zeros. Either the ones or the zeros are added up. If the total is even the parity bit is set to one. If the total is odd it is set to zero. This is called even parity. There is also odd parity. This method is used in many different places in a computer to ensure the data has not changed or been corrupted. Parity has limited accuracy and is usually replaced with CRC (cyclic redundancy count) which is far better at trapping errors and is also much more complex. It is generated with prime numbers and a series of exclusive or functions which is an add with no carry. If a parity error occurs whatever data created the error be it in memory or in a file or even a transmission it lets the system know the data is not reliable. If it occurs in OS operating memory the parity error won't affect anything but the damaged data will. Usually the system will halt at this point. So the answer to the question is the error won't cause anything the corrupted data can-but the parity can be trapped to perform special error handling procedures.

EEratic Behaviour!!!??
Sorry friend....Normally Parity wont be a problem when you dont know that there is no Parity chip in the Memory or Parity Error Detection Mechanism. If you know that those are not available in the computer, then you will feel whatever the problem comes will be due to Parity Error...Sounds Psychic right??

Possibly the ram (Memory) in your computer is going bad, or you have parity error checking turned on for the ram, and it doesnt support it. Check that first, then the ram. Sometimes, a ram can loosen in the mother board due to thermal expansion (Heat causing the chip to push up out of the socket), in which case you will need to reinstall the ram by pushing it gently back into the slot. But, truthfully, if the computer is set for error checking, and the ram isnt compatable with error checking, then you will have to adjust the settings in your bios, otherwise, I would suspect a falty simms (Ram) .

parity errors can cause very erratic errors and from my past expience at working in a service department for ten yours at a major computer manufacturer is that 9 out of ten times it is the memory causing it. If you have two memory sticks in your system pull one out for awhile and try it and then put the other one back in by itself and run that run and see what happens

Either the memory is defective, or it needs to be re-seated, with the power off, and wearing a ESD wrist strap os you don't blow it all from the static discharge!
