Spontaneous reboots: memory problem?

[Boris Zakharin]

After having purchased 512MB DDR RAM, I'm getting spontaneous reboots in
Windows XP about every 24 hours (not an exact figure). I'm not certain the
memory is the problem. The following are the stop codes I was able to
retrieve from the Eventlog. They're not always the same:

0x0a (IRQL_NOT_LESS_OR_EQUAL)
0xdb (DRVER_CORRUPTED_SYSPTES)
0x1000007e (SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M)
0xd1 (DRIVER_IRQL_NOT_LESS_OR_EQUAL)

Is this enough information to pinpoint the problem? I've run memtest86 for 2
cycles without problems.

If the problem only appeared after adding RAM, then the RAM is suspect.
Run the memory tester from www.memtest.org overnight and check the results.

25 hours 0 errors. What else could it be?

Does restoring the memory configuration to what it was before cause the
problem to disappear?

(Since you mentioned that the problem appeared after upgrading the memory)

I'd have to run with the old configuration for days to be sure. The reboots
aren't frequent and going back to 256 MB would really slow it down.

Try http://home.earthlink.net/~alegr/download/memtest.htm

Run with /preheat option. If you choose to run it under Windows, run it with
disk I/O thread.

Well, the other normal cause of random reboots is usually the power
supply. My system is sadly suffering from just that problem (err, at
least I really hope it's the power supply since I've got a new one on
order! :> ). Unfortunately, short of replacing the power supply with
a known-good one it's rather tough to test power supply problems.

Have you loaded any new drivers since the memory upgrade? Are you running
a (old) virus scanner which might be incompatible with XP?... maybe try
disabling the scanner. The indications are that someting is awry in the
system page table requests/allocation, possibly caused by a rogue driver -

You might try checking that all your system files are intact:

SFC /PURGEALL
SFC /SCANNOW

Also look for driver updates.

I'm not sure about the driver, but I notice that the last event in the log
prior to the latest crash (almost exactly 50 minutes earlier) is a warning.
Event ID 3019 source MrxSmb "The redirector failed to determine the
connection type." Looking at MS Help, this is normal. In fact, the time
begfore the second to last crash the message appears 7 times in a row before
the crash. However, in two cases this warning is absent. The last messages
from those are: "The SetupNTGLM7X service was successfully sent a start
control" and "The system detected that network adapter MAC Bridge Miniport
was connected to the network, and has initiated normal operation over the
network adapter."

An error that often comes up in the log, but not in any relation to the
crash is 6004: "A driver packet received from the I/O subsystem was invalid.
The data is the packet." Now this souds like a network driver problem.
However, which one? I've got two physical Ethernet cards, one card that
represents a USB DSL modem, a network bridge, and two VMWare adapters.

Try moving the new ram to another slot. If this works then it means the slot
is bad.

IMO given the frequency of crashes, 25 hours and 0 errors doesn't
rule out memory problems.

I recently worked on a new PC with > once/day BSOD (blue screens of
death), yet it passed memtest flawlessly the first run (overnight).
After a few days and several more BSODs, I ran Memtest again and it
found errors.

After replacing memory the system has been reliable.
