The computer restarted unexpectedly or encountered an unexpected error. Windows Installation cannot proceed.

    Question

  • When one of our users was working (in Microsoft Outlook) on his computer, his computer got restarted to the following Error Message: "The computer restarted unexpectedly or encountered an unexpected error. Windows Installation cannot proceed. To install Windows, click "OK" to restart the computer, and then restart the installation."

    This is a HP 520 Notebook preinstalled with Vista Business 32bit.

    I tried booting with a Linux Live CD to back up the data, but strangely the folder with his username (under Users) is not present. Have we lost the data ?

    Something which might have any connection to my problem: I recently (about a week ago) added a 2 GB RAM module in this Notebook, and now the total is 2.5 GB. (The Notebook manual said 2 GB is the maximum RAM to be used in teh Notebook.) 

    Any help is much appreciated.

    Regards

  • Hi,

    I removed the 2 GB module, and put back the old 512 MB one. But there is no change - same message continues to appear on restart.

  • OK, now I have put the disk on Recovery of Data; but could someone tell something of the Error Message, and suggest a solution so that I do not have to format and reinstall everything back ?

    Thanks

  •  Hi,

     

    Thanks for posting in Microsoft TechNet forums.

     

    This error probably indicates a hardware the compatibility issue between your motherboard and RAM. Could you please tell us the make and model of your motherboard and RAM?

     

    You may need to adjust the DDR voltage leave AHCI turned off from BIOS to check the result. With regards to BIOS, please understand that it requires the hardware manufacture to do some research and publish an updated BIOS that is compatible with the operation system and hardware.
