Intermittently, I receive the blue screen of death (BSOD) with the following message:
PAGE_FAULT_IN_NONPAGED_AREA
STOP: 0X00000050 (0XF000B084, 0X00000000, 0XF7381355, 0X00000000)
SRESCAN.SYS - ADDRESS F7381355 BASE AT F737B000, DATESTAMP 459E1537

I have a 2003 Dell Dimension 4550, so I used their diagnostics at boot-up and get the following (sometimes it passes the diagnostics without a message):

ERRORCODE 0F00:133D
MSG:IDE DEVICE FAILED: INCOMPATIBLE CD FOR TESTING

or

IDE DISK-SEEK TEST
ERROR CODE 0F00:0442
MSG: BLOCK 268435455: ADDRESS NOT FOUND

I ran the IDE Drive Diagnostics on the Boot Device Menu and it passes.

I ran the Western Digital hard drive diagnostics TOOL on my c:drive (it's a Western Digital HDD) and it passes.

I'm getting intermittent failures from something.  Is my hard drive about to fail?
I think your hard drive is about to go but,
download and run stability test 6.0 it's free.

Q: How do I KNOW if my computer is stable?
A: If it crashes while testing it is not.

Q: What test method I should use?
A: Use 'Normal Testing'.

If it does not crash recommended 12
hour running of program.


http://www.majorgeeks.com/download215.htmlJust FYI.  I downloaded the program and ran it over 12 hours and it didn't crash.  I guess I'll have to wait and see what happens.That also might possibly be pointing to memory errors...DLoad and run MemTest as well.I downloaded and ran MemTest for 40-45 minutes (208% coverage) and it didn't crash it either.Have you recently re-installed your OS on this machine ? ?
List any new hardware installed in the last few months...even if you have since uninstalled it.No, I haven't REINSTALLED my OS or installed/removed any hardware recently.http://support.microsoft.com/search/default.aspx?query=page+fault&x=0&y=0&catalog=LCID%3D1033&spid=&qryWt=&mode=r&cus=FalseThanks for the link, but I couldn't find anything that applied there.  But I did a search and did find something that may help.  Good info for anyone that uses ZoneAlarm Free Firewall v7.0.302.000.
