Stop 0xC2 or BAD_POOL_CALLER The Stop 0xC2 message indicates that a kernel-mode process or driver incorrectly attempted to perform memory operations in the following ways: • By allocating a memory pool size of zero bytes. • By allocating a memory pool that does not exist. • By attempting to free a memory pool that is [...]

Stop 0xBE or ATTEMPTED_WRITE_TO_READONLY_MEMORY The Stop 0xBE message indicates that a driver attempted to write to read-only memory. Possible Resolutions: • A Stop 0xBE message might occur after installing a faulty device driver, system service, or firmware. If a Stop message lists a driver by name, disable, remove, or roll back the driver to correct [...]

Stop 0x0000009F or DRIVER_POWER_STATE_FAILURE The Stop 0x9F message indicates that a driver is in an inconsistent or invalid power state. Possible Resolutions: • Stop 0x9F messages can occur after installing faulty applications or drivers or system services. If a file is listed by name and you can associate it with an application, uninstall the application. [...]

Stop 0x0000007F or UNEXPECTED_KERNEL_MODE_TRAP The Stop 0x7F message indicates that one of three types of problems occurred in kernel-mode: • A condition that the kernel is not allowed to have or intercept (also known as a bound trap). • Software problems. • Hardware failures. Possible Resolutions: • Stop 0x7F messages are typically due to defective, [...]

Stop 0x0000007B or INACCESSIBLE_BOOT_DEVICE The Stop 0x7B message indicates that Windows XP has lost access to the system partition or boot volume during the startup process. Installing incorrect device drivers when installing or upgrading storage adapter hardware typically causes stop 0x7B errors. Stop 0x7B errors could also indicate possible virus infection. The second parameter is [...]

Stop 0x0000007A or KERNEL_DATA_INPAGE_ERROR The Stop 0x7A message indicates that a page of kernel data was not found in the paging (virtual memory) file and could not be read into memory. This might be due to incompatible disk or controller drivers, firmware, or hardware. Frequently, the cause of this error can be determined from the [...]

Stop 0×00000079 or MISMATCHED_HAL The Stop 0×79 message indicates that the hardware abstraction layer (HAL) and the kernel type for the computer do not match. This error most often occurs when ACPI firmware settings are changed. For example, you might install Windows XP on an x86-based computer with the firmware ACPI enable option enabled and [...]

Stop 0×00000077 or KERNEL_STACK_INPAGE_ERROR The Stop 0×77 message indicates that a page of kernel data requested from the paging (virtual memory) file could not be found or read into memory. This Stop message can also indicate disk hardware failure, disk data corruption, or possible virus infection. Possible Resolutions: • Stop 0×77 messages can be caused [...]

Stop 0×00000050 or PAGE_FAULT_IN_NONPAGED_AREA The Stop 0×50 message indicates that requested data was not in memory. The system generates an exception error when using a reference to an invalid system memory address. Defective memory (including main memory, L2 RAM cache, video RAM) or incompatible software (including remote control and antivirus software) might cause Stop 0×50 [...]

Stop 0x0000003F or NO_MORE_SYSTEM_PTES The Stop 0x3F message indicates one or more of the following problems: • The system Page Table Entries (PTEs) are depleted or fragmented due to the system performing a large number of input/output (I/O) actions. • A faulty device driver is not managing memory properly. • An application, such as a [...]

Stop 0x0000002E or DATA_BUS_ERROR The Stop 0x2E message indicates a system memory parity error. The cause is typically failed or defective RAM (including motherboard, Level 2 cache, or video memory), incompatible or mismatched memory hardware, or when a device driver attempts to access an address in the 0x8xxxxxxx range that does not exist (does not [...]
