BSOD STOP 0xa 0x1e 0x50 0x7F

When you read the newsgroups, you will see common questions/answers on Blue Screen of Death error messages ( BSOD ). The common stop messages are:

  • STOP: 0x0000000a :
    STOP: 0x0000007f :
    usually hardware failure involving the memory, processor, or motherboard
  • STOP: 0x0000001e :
    usually hardware failure involving the memory, processor, or motherboard
    - or -
    problem related to anti-virus software
  • STOP: 0x00000050 :
    problem related to anti-virus software
    - or -
    problem with 3rd party software installed service
With STOP 0x7F, 0xa or 0x1e I would substitute known good memory, check that all cards are inserted well and that all connections are firm. With STOP 0x1e or 0x50 uninstall the antivirus software and disable any new services to troubleshoot the problem.

STOP 0x7F can be software but it is almost always a corrupt motherboard or RAM.

Consider Blue Screen Administration for Windows NT and 2000
offers you the chance to administer your Windows NT and Windows 2000 after a Blue Screen and fix boot errors or save data from defunct volumes. You can boot NT/2000 from disk and so gain access to systems whose passwords have been forgotten.

If the BSOD is a kernel error, the KERNEL_STACK_INPAGE_ERROR, this BSOD takes place when the kernel requests a page of data from the swap file, but the page cannot be read into memory. This error returns four parms. The first two parms are useful in determining what the problem is:

parm 1 normally has values 0-2

  • 0: The page was retrieved from an in-memory page cache
  • 1: The page was retrieved from disk
  • 2: The page was retrieved from disk, but its size appears to be mismatched
And surprise, surprise, this is usually caused by a defective RAM module.

If parm 1 is greater than 2, parm 2's value means:

  • 0xC000009A (STATUS_INSUFFICIENT_RESOURCES) : ran out of nonpaged pool resources
    0xC000016A (STATUS_DISK_OPERATION_FAILED): defective hard drive sectors
  • 0xC000009D (STATUS_DEVICE_NOT_CONNECTED): bad cable or improper termination of cable to HD
  • 0xC0000185 (STATUS_IO_DEVICE_ERROR): improper termination or I/O conflicts
Just open the box and reset the card and cabling. Most likely something has vibrated loose. Try this even for 9C and 16A. If this is a new box, these errors may indicate a defective motherboard.
