Hold mouse here for list of most recent changes. These appear only in the NT- based operating systems: Win NT, Win 2. Win XP, and Vista. Most are hardware issues. STOP messages are identified by an 8- digit hexadecimal number, but also commonly written in a shorthand notation; e. STOP 0x. 00. 00. 00. A may also be written Stop 0x. A. Four additional 8- digit hex numbers may appear in parentheses, usually unique to your computer and the particular situation. NOTE: Many users search this site for the word minidump which often accompanies these Stop Message errors. The fact that a memory minidump occurred tells you nothing except what you already know — that there was an error. It is the name of the error condition and its 8- digit number that help you determine the actual error condition. If a message is listed below, but has no articles or explanation (nothing but its number and name), post a request on the Aum. Ha Forums asking about it. STOP messages of this type are rare, obscure, and usually only of interest to programmers debugging their code. Real- life scenarios of a computer user encountering them are unlikely, so I’ve made it a lower priority to document them here; but we’ll be happy to address this in the Forum (which also will tip me off that I should add more to this present page). General Troubleshooting of STOP Messages. If you can’t find a specific reference to your problem, running through the following checklist stands a good chance of resolving the problem for you. This checklist is also usually the best approach to troubleshooting some specific Stop messages, such as 0x. A and 0x. 50. Examine the “System” and “Application” logs in Event Viewer for other recent errors that might give further clues. To do this, launch Event. Vwr. msc from a Run box; or open “Administrative Tools” in the Control Panel then launch Event Viewer. If you’ve recently added new hardware, remove it and retest. Over the past several weeks the lock screen has been seriously importuning. It’s been pissing me off. After about 60 seconds of inactivity the computer.

If you have multiple user accounts on your computer, you might find it annoying to have to click on the icon for your username each time you start up the computer. Run hardware diagnostics supplied by the manufacturer. Make sure device drivers and system BIOS are up- to- date. However, if you’ve installed new drivers just before the problem appeared, try rolling them back to the older ones. Open the box and make sure all hardware is correctly installed, well seated, and solidly connected. Confirm that all of your hardware is on the Hardware Compatibility List. If some of it isn’t, then pay particular attention to the non- HCL hardware in your troubleshooting. Check for viruses. Investigate recently added software. Examine (and try disabling) BIOS memory options such as caching or shadowing. NOTE: When a STOP message occurs, Windows can create a debug file for very detailed analysis. To do this, it needs a workspace equal to the amount of physical RAM you have installed. If you resize your Win XP pagefile minimum to less than the size of your physical RAM, you will get an advisory message that your system may not be able to create a debugging information file if a STOP error occurs. My advice is to go ahead with this change if you want, but simply remember the limitation so that you can change it back if you need to troubleshoot STOP messages. Some general troubleshooting principles are suggested in the Resource Kit for approaching STOP messages overall. APC. A specific problem is known to exist with Win XP SP2 and Server 2. Microsoft. 0x. 00. INVALID. Use the General Troubleshooting of STOP Messages checklist above. Technically, this error condition means that a kernel- mode process or driver tried to access a memory location to which it did not have permission, or at a kernel Interrupt Re. Quest Level (IRQL) that was too high. Start with the General Troubleshooting of STOP Messages checklist above. Read the MSDN article linked here. Especially try to track it down by noting the history of the problem, when it appeared, and what changes were made to the system since the problem first appeared, as well as noting what activity you are attempting at the time the error message appears. EMPTY. Device driver issues are probably the msot common, but this can have diverse causes including bad sectors or other disk write issues, and problems with some routers. See the General Troubleshooting of STOP Messages checklist above. If this occurs while installing Windows, also check the Windows system requirements including the amount of RAM and disk space required to load the operating system. If none of the above resolves the problem, see the MSDN article linked above for further steps. B: PFN. A Stop 0x. E condition can be caused by invalid memory and access violations similar to those that generate Stop 0x. A errors. This default Windows error handler typically intercepts these problems if error- handling routines are not present in the code itself. Possible Resolutions to STOP 0x. A, 0x. 01. E, and 0x. Errors . There may be a physical problem with the disk, or an Interrupt Request Packet (IRP) may be corrupted. Other common causes include heavy hard drive fragmentation, heavy file I/O, problems with some types of drive- mirroring software, or some antivirus software. I suggest running Chk. Dsk or Scan. Disk as a first step; then disable all file system filters such as virus scanners, firewall software, or backup utilities. Check the file properties of FASTFAT. SYS to ensure it matches the current OS or SP version. Update all disk, tape backup, CD- ROM, or removable device drivers to the most current versions. NTFS.

SYS to ensure it matches the current OS or SP version. Update all disk, tape backup, CD- ROM, or removable device drivers to the most current versions. NPFS. Memory management issues can be one cause, and adding additional RAM commonly will resolve this version of the problem. The articles below give the best information on troubleshooting and resolving the problem. CORRUPT. It also can indicate hard disk damage caused by viruses or other problems. F: INSTRUCTION. Remove any recently installed software (especially disk- intensive applications) and recently installed drivers. TARGET. In practice, it is usually a hardware driver issue. INSUFFICIENT.

If Windows is loaded and no new hardware has been installed, reboot with recovery options set to create a dump file. If the message recurs, press F8 and select the Last Known Good option when you reboot. If there is no Last Known Good configuration, try using the Emergency Repair Disk. B: SET. Typically there is a problem with a device driver or with a missing or corrupt system file used during Windows startup. SESSION4. In practice it is often caused by RAM problems or other issues mentioned in the articles below. CANNOT. The article linked here contain a method to track the problem if it recurs, and identify the problem driver. This message also can indicate disk hardware failure, disk data corruption, or possible virus infection. PHASE0. This most often occurs when ACPI firmware settings are changed. For example, you might install Win XP on an x. ACPI enable option enabled and later decide to disable it. This error can also result when mismatched single and multi- processor configuration files are copied to the system. A: KERNEL. This might be due to incompatible disk or controller drivers, firmware, or hardware. B: INACCESSIBLE. Typical causes: Installing incorrect device drivers when installing or upgrading storage adapter hardware, or a virus. C: BUGCODE. There are numerous individual causes for this problem, including hardware incompatibility, a faulty device driver or system service, or some software issues. Check Event Viewer (Event. Vwr. msc) for additional information.“0x. E, 0x. C0. 00. 00. FC5. CCAF3, 0x. FC9. F8. C0, 0x. FC9. 0F5. C0” Error Message at Startup .
