    PC consistently powering down abruptly

    One of my family members is experiencing a PC that is consistently powering down abruptly.

    I checked into the windows error log and I'm not able to make sense of it.
    I suspect a faulty PSU or rail might also be in play.

    In general (with a hardware error) what we look for is either random errors - or no evidence of a problem in the Windows logs.
    This is not 100% certain - but it does give us a direction to start looking in.

    Your UEFI/BIOS dates from 2010. Please check at the manufacturer's website to see if there are any UEFI/BIOS updates available for your system. Also check the readme file to see if they apply to the problems that you are having. Please be advised that flashing the UEFI/BIOS is a very unforgiving process - and one mistake can physically damage your motherboard. If possible, use the "inside Windows" flash mechanism (if your OEM provides one) - that is much more forgiving than the traditional (floppy drive) flash method.

    Only 89 Windows Updates installed. Most systems have 100 or more. Please visit Windows Update and get ALL available updates (it may take several trips to get them all).

    Don't worry about the specific number, it's just important that you have checked and installed any updates that were available (and didn't experience any errors).

    Beyond that, there isn't much showing wrong that I can see. In most cases, this means it's most likely a hardware problem.
    Please start with these free hardware diagnostics: Hardware Diagnostics

    Why do you suspect the PSU? IME most problems are solved by the owner, so that's why I ask.
    FYI - the only sure test for a PSU issue is to replace the PSU with one that's known to be good (or a new one).
    Don't do that yet - we'll work on some more diagnostics to help isolate the problem.
    Should you start buying replacement parts, make sure that you get them from a retailer that'll let you return them for a refund if they're not needed.

    Finally, this report will help us a bit more (it makes searching for patterns easier):
    Please do the following:
    - open Event Viewer (run eventvwr.msc from the "Run" dialog)
    - expand the Custom Views category (left click on the > next to the words "Custom Views")
    - right click on Administrative Events
    - select "Save all Events in Custom View as..."
    - save the file as Admin.evtx
    - zip up the file (right click on it, select "Send to", select "Compressed (zipped) folder")
    - upload it with your next post (if it's too big, then upload it to a free file-hosting service and post a link here).

    FYI - If we're looking for Event ID 41 errors (unexplained shutdowns), there's more info on that here: Windows Kernel event ID 41 error "The system has rebooted without cleanly shutting down first" in Windows 8.1, Windows 8, Windows Server 2012 R2, Windows Server 2012, Windows 7, or Windows Server 2008 R2

    While waiting for a reply, please monitor your temps with this free utility: HWMonitor CPUID - System & hardware benchmark, monitoring, reporting

    I did not see usasma's post. Kindly follow his post
    Hi TapAttack & Welcome to the forums ^_^,

    I have analysed your log files and they don't contain any Dump files so we know that this is not being caused by a Blue Screen. Plus the event logs also say so.

    Unfortunately, I did not find any errors which could tell me the reason behind the mysterious shutdowns. Could you please run the Hardware Diagnostics (thanks usasma) -
    Hardware Diagnostics

    Also, what is the age of your Power Supply? According to the support website, there is a BIOS update available but it only supports Windows 7-
    Product Support | Dell US

    Did this problem occur when you were using Windows 7?

    Let me know how it goes ^_^

    Thanks for the help
    I've attached the events in the zip below.

    I suspect this is a faulty PSU because of the way the owner described the constant sudden shutdowns which have been plaguing the machines. Also this is an OEM made machine and the PSU's they use aren't the most robust - I know I'm being a little biased here

    There doesn't seem to be a pattern to the shutdowns, so I also suspect a hardware problem.
    There are several disk type errors in the events - so I suggest running these free diagnostics (starting with the hard drive tests): Hardware Diagnostics

    There is a BSOD (STOP 0xFE) from 27 Dec. And there are a couple of errors where crash dump initialization has failed. Add to this some storage related stuff and the hard drive seems to be the prime candidate here.

    Please locate C:\Windows\MEMORY.dmp, zip it up, and upload it to a free file-hosting service (such as OneDrive/SkyDrive or DropBox) and post a link here so we can analyze it.

    Now, just to add to the confusion - this particular STOP code is related to a USB driver.
    What USB devices do you have connected to the system?

    Thanks for the response.

    I should have posted this information earlier but I'm actually not that familiar with this machine myself.
    This machine currently has 1 SSD, 1 mechanical drive and 2 CDs drives.
    Windows 8.1 pro was installed to the SSD. The SSD is new (2-3 weeks).

    The owners of this pc swapped out the old PSU on 12/28 and a new one was placed inside.
    It hasn't really been extensively used since the new PSU was placed in so I'll see how it goes.

    The only usb devices normally connected are the keyboard and mouse.
    Sometimes a phone charger for an android or iphone.

    However, I believe on the Dec 27 date a portable usb hard drive was also connected to the pc (I believe it was used to backup some files).

    I've attached the memory.dmp at Microsoft services (onedrive)

    I'd be sure to run the hard drive diagnostics on the USB hard drive.

    Waiting on the download of the MEMORY.dmp file. Will post the analysis once it completes..................

    The MEMORY.dmp file was the dump for the 27 Dec BSOD.
    It blamed USB drivers. The look and feel of the dump is that of a hardware problem. (little info, limited number of 3rd party drivers in the dump, and unexplained Event ID 41 errors).

    I'd rule out the USB devices (particularly the USB hard drive), and then see if you get issues without them being attached.
    Don't use the USB hard drive until the system has been stabilized (after doing the diagnostics).
    Try another keyboard and mouse in different USB ports (I prefer using the ports in the back of the system as they are directly connected to the motherboard). This is not likely, but it's still a possibility.
    As for the phone charger, I'd suggest a wall or car USB charger device - and don't hook the phone to the system until the problems are solved (there were BSODissues with USB charging drivers in Win 7 and maybe in the early days of Win8).

    Once the USB stuff is taken care of, then we wait to see if the problems recur....................

    Here's the memory dump analysis. It's just for info purposes:
