When you start your computer, you are greeting with the following BSOD:
STOP 0x00000067 (0x00000004, 0x00000008, 0x00000000, 0x00000000)
Windows is unable to allocate the required memory pool for your registry files.
Make sure you are running a current service pack. If you are, the problem is likely to be a defective RAM module.
If replacing the RAM doesn't resolve the problem, try disabling caching on your motherboard.
NOTE: The problem can also occur when you boot the Windows CD-ROM to perform an install.
