Brother Printer Driver Part
Brpar.sys (WinNT/2K/XP) - This file is used for bi-directional communication when using the parallel interface. By uninstalling this option you will disable all parallel port bi-direction communication.

I believe BrPar was installed by me when I used a Brother parallel printer. I have removed the printer a long time ago but I was getting regular errors in my system log and it was contributing to my pc freezing. I have renamed BrPar instead of deleting it and I am now waiting to see if it has got rid of the problems.
It seems to be a driver installed when I installed my Brother 1440 printer. It is located in both the following directories: c:/brother\BRDriver and c:\windows\system32\drivers. It my be causing my XP-sp3 to lock up, it is the only error in the event log at the time the system freezes.
I have a Brother 1450 and could experience the same: The moment my system freezes, it is protocolled that this file caused an error. I try to reinstall it because until 2 weeks ago there was no problem at all...
remains of the brother printer driver (uninstalled printer, windows still shows message that brpar service failed to start, f*** brother)

Best practices for resolving BrPar issues

A clean and tidy computer is the key requirement for avoiding problems with BrPar. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
