    Is there an “uninterruptible power supply” connected to your computer? If yes, make sure that it is receiving power and the battery is able to hold a charge.

    Do you get any sort of message and/or special screen when your computer shuts itself down? If yes, please tell me what it says. You might be facing an issue with software and/or external devices that you’ve added to your computer.

    Assuming that neither UPS nor software malfunction is the source of your problems, you are probably facing either a BIOS issue or an internal power supply problem. These two are the most likely causes. Other possibilities include a loose cable inside your computer, a dying hard drive, malfunctioning graphics card, dying motherboard, etc.

    Go into your computer’s BIOS by pressing the button listed on the screen when your computer first turns on. If no button is listed, try F2, Del, or Esc. Make note of all settings in the BIOS. Exit the BIOS and then visit your computer manufacturer’s support website, enter the model information, service tag, etc that will allow the website to identify your computer. Then download the latest BIOS version for your computer and install per manufacturer instructions. If the BIOS update does not install, your computer probably has the latest possible BIOS. Regardless of success or failure of the update, you may wise to run the “recommended defaults” in your bios for awhile to see if your computer becomes more stable.

    If yours is an internal power supply problem, you will need to replace your existing internal power supply with a new one. The internal power supply itself is rather inexpensive and easy to replace. However, there are many cables going from the internal power supply to your motherboard, hard drive, optical drive, etc that you’ll need to disconnect when you remove the old internal power supply. You’ll then need to CORRECTLY reconnect similar cables after installing the new internal power supply. If you are not comfortable working inside a desktop computer, I recommend that you consult with a computer hardware expert in your area for assistance.

    Do these ideas help?


    No message recieved on shutdown. Sometimes mouse freezes. I think power suply is ok. Have re installed windows yet agian and system works ok until I put ati drivers back on the system. I am folowing your advise above to get the latest bios and will report back.
    Many thanks for your help so far.


    Some information… PS/2 is a round connection, probably at the top-back of your computer. Of course, USB is rectangular.

    Some questions… Are you using a PS/2 or USB connection for your keyboard? Are you using PS/2 or USB for your mouse? Are there any USB to PS/2 adapters involved? If using any USB connections, are you using built-in ports or a separate USB card?

    Thanks for taking a moment to answer all of the above questions. Your answers will help me to better assist you.


    Both mouse and keyboard ps/2 and no usb to ps/2 adadpters involved.
    Have followed your advice and no bios issues either.
    Windows will work although slowly until i reinstall the video driver when all hell breaks loose, the system freezes/crashes and then proves difficult to re-boot.
    At present i have no sound or video drivers,
    Any further help gratefully recieved


    Go these 2 messages after latest shutdown
    WINDOWS\MIMIDUMP\MINI 022209-01.dmp
    DOCUMNT\gaz\LOCALS~1\TEMP\WER 1. tmp.dir 00\sysdata.xm1
    could this describe the problem?


    Hi Gaz,

    I did some research based on the error messages that you’ve provided. Unfortunately, there does not appear to be a conclusive answer to what these error messages represent — so people suspect a graphics driver issue while others suspect hardware malfunction.

    Your PS/2 mouse freezing makes me suspect a hardware failure in your computer more than a driver problem. The hardware malfunction could be motherboard, graphics card, and/or RAM. With the additional information you have given, I agree with you that the internal power supply in your computer is probably not malfunctioning.

    Do you have any spare computer parts that you can use to run some tests (e.g. different RAM to see if your current RAM if faulty)? If yes, I’d be happy to provide instructions to help you with further troubleshooting. If no, I recommend that you consult with a hardware expert in your area.

    If your computer is more than 5 years old, you may wish to consider purchasing a new computer instead of spending time/money trying to fix your current one.

    How do you wish to proceed?


    Hi Roebert.
    Your advice has been spot on. I have taken the computer to a hardware specialist who is running tests on the blinkin thing. His initial prognosis agrees with your last reply above.
    Thanks again and take care,

    Hello, I have the exact same problem and I was wondering what the exact issue was for Gaz1000.
