    I have a pc that keeps shutting down at random times. I collected the memory dump files (3) and am not sure how to read them. Any help would be appreciated.

    Here are all 3 minidump files:

    PFN_LIST_CORRUPT (4e)
    Typically caused by drivers passing bad memory descriptor lists (ie: calling
    MmUnlockPages twice with the same list, etc). If a kernel debugger is
    available get the stack trace.
    Arguments:
    Arg1: 00000099, A PTE or PFN is corrupt

    Arg3: 00000000, current page state

    IRQL_NOT_LESS_OR_EQUAL (a)
    An attempt was made to access a pageable (or completely invalid) address at an
    interrupt request level (IRQL) that is too high. This is usually
    caused by drivers using improper addresses.
    If a kernel debugger is available get the stack backtrace.

    Start by testing your memory. Run Memtest86 or Windows Memory Diagnostic.

    Please note:

    Ran Dell's system test. Everything passes (including the log memory test). Not sure if it is a bad driver or if I have a krnl going bad...

    Will try the other two memory tests.

    Thanks

    As I posted:
    So your memory still could just be faulty & pass the test.

    Try running with one memory stick at a time, try running them in different slots.

    I ran Dell Diagnostics, Windows Memory Diagnostic, and MemTest86. I tried all three with single module installed, using different slots. All passed with no errors. Other thoughts?

    Thanks!

    I've already posted my "other thoughts ", so if you tried those, then no.

    Yes, you have a memory problem. Oops, you've already been told that a couple of times. Perhaps you want to list what you have for installed memory and what the current memory settings are. Give us that along with the motherboard and CPU specs and perhaps there is an easy fix. No promises but ......

    ;)

    Did you build your system? If so, check to see that you didn't accidently get any thermal grease on your RAM modules. I accidently did, and was getting constant memory errors. Once I wiped it off, it was fine.

    I would point out in Arie's quote:
    So it can pass the tests, but still not work in Windows.

    Other thoughts...
    You say in the title that the system "shuts down ". Check that the system is not overheating. Check that all the fans are spinning freely when it is running, including the PSU fan and graphics card fan if it has an add-in graphics card with it's own fan.

    Let us know some details about the system (Rockster's post). How long have you had the system running with the present hardware arrangement? If you run out of possibilities, consider that there may be a power supply problem.

    Thanks Matt,

    The system does not look to be overheating. There are 3 fans total, and all are working. The system has been running for at least 6 months with the same configuration, used by the same user. The power supply was sometihing I was thinking about, but I noticed that the system was set to shutdown after a fatal error, not blue screen. So I am putting the idea of the problem being the power supply on the back burner for now, but I agree, it is still a possible culprit.

    If you are happy to spend a little time on it, do all the basics. Run Error Checking (CHKDSK) on each drive. Clean up the HDD and uninstall any unnecessary (junk? :)) programs. Do a defrag.

    Look for drivers that are up to date with Service Pack 3, especially the chipset drivers. If there are no new drivers at Dell, try looking for them at chipset manufacturer's website (Intel?).

    I swap out the RAM modules with compatible types for testing. See if Rockster has some suggestions.

    Last but not least: Try a new PSU (Power Supply Unit).

    iBooger - unfortunately nothing jumps off the page screaming, "Fix me, Fix me ".

    I've always had pretty good luck with Samsung memory and considered it a very good choice for the money. Ive also used single sticks with similar mfg dates in dual channel systems (Samsung doesn't sell dual channel per se) the same way you are using it. So what to do now?

    The only spec you are not in conformity with is CAS or (tcl) which should be 5 and you are running at 6. This is no big deal and 6 should give you more latitude anyway so I don't see this as a potential fix. Your voltage is stated at 1.8 which is the spec but as has already been suggested, you can try another PSU. Why would this matter? Just because your machine says its putting out 1.8V doesn't mean its so and an underpowered SSTL value will throw errors. A new PSU may give you a more stable and correct voltage (speculative but worth a try).

    As another option, if your BIOS will let you adjust this manually, set it at 1.9V. That's only about a 5% increase and its not going to do any damage to anything (short term or long term). The fact that you have a Dell machine probably means the BIOS is crippled and isn't going to let you make this change but its worth investigating.

    Lastly, I'd encourage you to consider buying some better memory that your machine is going to be nicer to. Get some low latency OCZ over at NewEgg and buy a dual channel pair of sticks that have been tested and packaged as such. Right now you can get 4 Gigs for 69.99 with a $30 rebate. (I just bought some for someone else).

    Good Luck and keep us posted.

    ;)

    Thanks all for the help... I have another Dell 755 with the exact same setup, that I am going to try to swap memory modules. Going to run the other memory in the new pc to see if I get the same shutdowns. Thanks for all the suggestions. I really appreciate it.

    Hi iBooger...just want to add on to the great advice you are getting here.

    Is your Dell still covered by warranty or should I ask...did you get warranty for this unit? Depending on what coverage was purchased at the time of the PC purchase you might be covered by Dell Technical and could have a Dell Cert. Tech come out to your place and repair. No, I don't work for Dell, :) We just use Dell PC's\Laptops\Workstations at my place of work. When I order the units I will usually pick Dell Gold Warranty for approx 3 to 4 yrs and it has definitely been used.

    Also if you do have warranty you might not want to do anything to drastic that will void the warranty.

    Well, I took the other system and swapped both memory modules. Same memory type (Samsung), same computer (Dell Optiplex 755 mini).

    I have not received errors on either system since... Not sure what is going on, but both systems seem to be running with no problems.
