Windows 7 Instalation Problem - Error Code 0xC0000005


  • I have been trying to install Windows 7 on my, rather old, laptop and it barely gets to the installation screen after inserting the CD into the CD drive when the message appears:

    Windows installation encountered an unexpected error. Verify that the installation sources are accessible and restart installation. Error code: 0xC0000005

    I don't know why this message keeps appearing...

    I ran the windows 7 upgrade advisor and it then said that my current graphics adapter will not support Windows Aero user interface and also to upgrade the drivers for my wireless and my ethernet - is it because of this that I cannot install windows 7? And if so, I was also not able to figure out how to find the updates for these...

    - Intel(R) PRO/Wireless LAN 2100 3B Mini PCI Adapter
    - 3Com 3C920 Integrated Fast Ethernet Controllet
    - Windows Aero support.

    Any help or insight would be extremely welcome.

  • This could mean that there's something wrong with your hard drive.

    I'd suggest running a chkdsk and running diagnostics on your hard drive and memory from your hardware diagnostics menu before Windows starts booting. That's F12 on mine, but may be different (if available) on yours.

    Regarding your hardware, you may be able to find drivers either at the manufacturer sites or from a place like
