MAILSLOT_FILE_SYSTEM
STOP: 0x00000052
Description
The mailslot device driver may have a bug or there is a problem with memory.
This is a fatal Windows error, typically called a Stop message, Bug Check, or more commonly the Blue Screen of Death (BSoD). The system is in a forced reboot state. Any unsaved work is likely lost.
Sample Screen
A problem has been detected and Windows has been shut down to prevent damage to your computer.
MAILSLOT_FILE_SYSTEM
If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:
Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any Windows updates you might need.
If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.
Technical Information:

Beginning dump of physical memory
Physical memory dump complete.
Contact your system administrator or technical support group for further
assistance.
Text may appear differently depending on where the error occurs.
Additional technical information (hex values) specific to a machine are not shown.
You may have a defective memory. This is even more likely if it only occurs when the system is cold or hot, but not all the time. Use a memory tester to confirm if it is defective or if you have spare memory, try replacement.
Windows 7 and Vista include a Memory Test program when booting from the Windows Installation DVD. Step-by-step instructions with screen shots are available at Using System Restore on 7/Vista/2008 as part of System Recovery.
Several software products that also provide memory and video diagnostics includes Fix-It Utilities Professional and SystemSuite Professional. Other diagnostic products include Eurosoft's PC Check and Iolo's System Mechanic.
Additional Memory Solutions:
Confirm all the memory is of the same type and speed. Many motherboards only work correctly when the memory is installed with matched sets and matched speeds.
If you added or changed your memory just before this problem occurred, try reverting to the prior memory configuration to confirm it's the source of the problem.
Check that the memory is fully seated in the sockets. Memory sockets often have side latches that need to be upright to indicate the memory is correctly locked in place.
Confirm the memory resides in the correct slots on the motherboard. You'll need to refer to the motherboard manual to confirm this. There is little consistency, even within a single vendor. Some systems require that memory is installed as matched pairs, but not always adjacent to each other!
It's also possible the memory problem is on the video card, as they often contain additional memory. The video card should be tested and/or try a different video card to see if the problem goes away.

Get the Latest Drivers
6
Check if you are using the latest hardware drivers, especially the chipset and video drivers. Older drivers are a common contributor to BSoD issues.
You can use a product like Driver Genius or Radar Sync to verify you have the latest drivers and help keep all your drivers up-to-date. If you're comfortable with driver installations, you can individually find and install current drivers.
There was a problem detected in the mailslot file system.
The mailslot file system is similar to a disk file system, with files only temporally residing in memory. When the handle for the mailslot item is closed, the data is not saved anywhere.
While BSoD fatal stop errors are identified by Microsoft Windows, they are often caused by
non-Microsoft applications, drivers and hardware issues.
