How to fix a general protection fault.
There are several possibilities and reasons a computer receives a General Protection Fault error, below is a listing of some of the more common reasons.
- The program being used is calling a section of memory that is already being used by another program or TSR.
- The program has not been programmed properly or is still in testing and is calling an invalid portion of memory.
The following are recommendations for finding the cause of a GPF or resolving a GPF. It is important to know that GPFs are always likely to occur on the computer and if you are experiencing a GPF rarely such as once every few weeks to not worry about attempting to locate the root cause of that GPF. However, if you are experiencing GPF error messages often it is recommended you follow the following recommendations to help resolve your issues.
Remove all TSRs
Disable or unload any TSRs or programs currently running before running the program causing the GPF.
Delete all program temporary files
Delete all temporary files that may still be residing on the hard disk drive from currently or previously running programs.
Run ScanDisk and Defrag
Verify your computer has more than 200 MB available
If your computer is running low on hard disk space, your Windows Swap File will be unable to increase in size when needed, causing programs to be swapped between memory and the hard disk drive more frequently. When this occurs it is more likely that a GPF can occur.
Recently installed software or hardware
If you have recently installed new software or hardware uninstall or reinstall that software / hardware to verify it is not causing your issue.
Disable external cache
If your CPU utilizes external cache disable it temporarily to verify if it is causing your GPF error messages. If available, you will be able to disable your external cache through CMOS Setup.
Disable Power Management and screen savers
If you are receiving GPFs when away from the computer or during durations when your computer is inactive, disable Power Management and screen savers to ensure that they are not causing your issue.
Operating System issue
It is possible for Windows or an overwritten Windows related file to cause a General Protection fault. Most commonly the General Protection Fault with Explorer and KRNL386.EXE. Reinstall Windows to resolve the issue.
Bad memory or other bad hardware
If you have followed all of the above recommendations and continue to experience GPFs it’s possible hardware inside your computer may also be bad. Often bad memory is the primary cause for random GPFs.
