Tips on How to Resolve NMI: Parity Check/ Memory Parity Error
These are possible techniques on how to resolve this particular behavior. Try these subsequent suggestions.

Memory Check - Dislodge extra memory out of the motherboard; run only the module needed to start the system. Reboot the system to see of the error still exist. If the error message does not materialize, the problem is one of the memory cards you have removed from the motherboard. This procedure may take several times since you have to try every RAM to determine what causes the problem. If you have detected that a memory module is defective, replace it.

Adapter Check – Remove installed adapter leaving only the necessary adapter generally a single video adapter and the subsystem controller. Restart the computer to see if the problem sill occurs. Try to reinstall every adapter and reboot the system separately, reboot after every adapter. If the error does not appear after reinstalling each of the adapters, the card may only require to be reseated. Monitor the system to guarantee that the error will not reappear.

Check the BIOS Configuration – If you have reinstalled the necessary latest adapter or whatever revisions you have mage to the computer, verify this through your firmware of BIOS configuration application. Access the BIOS by pressing the Delete several times or F1 during the start up process until the BIOS appear. If you are inside the BIOS set it to BIOS default or Fail-Safe defaults, stop the antivirus application within the BIOS, and set the Plug-and-Play OS to “No”.

The kind of hardware the system uses as well as the manufacturer’s design of the motherboard verifies what component of the system’s firmware can generally be updated. Computer manufacturers offer diagnostic tools for the products troubleshooting.

Update the firmware, BIOS, or the EISA (European Imaging and Sound Association) configuration to be able to solve the problem regarding NMI: Parity Check/ Memory Parity Check,

If the following simple procedure does not resolve the problem, the problem could be simplified to the following, motherboard, hard drive, subsystem controller, or may be video adapter. RAID (Redundant Array of Inexpensive Disks) as well as other cache controllers processor chips or RAM that could cause the problem. If a simple configuration comprises these advanced adapters, to solve the problem may require the use of diagnostic or troubleshooting software.

Microsoft Corporation released a software diagnostic tool to be able to check Windows Memory and other peripherals.

My Lenovo T61 is reporting BSOD with NMI Parity Error. After a lot of sleuth work, I've established that it's the Nvidia GPU that's overheating and causing this error. Others have reported this. The cooling is just adequate for a non-GPU equipped T61, but when the GPU is added and the cooling fan starts to run slower (the main bearing in mine has gone, it rattles and screeches) the GPU overheats and the system goes BSOD.
