BSOD after Windows 7 upgrade RRS feed

  • Question

  • I am running an HP with Intel Core 2CPU 6400 @ 2.13 GHz  2 GB RAM 32-bit.  I upgraded from Vista after unistalling and deauthorizing the items it asked.  The only driver that appears to not be current is the Brother MFC-8500 printer.  I tried to install the driver from their website, got frustrated and just disconnected both printers.  Still no luck though...

    I took a picture of the blue screen and looked at it from my son's computer.  It told me to run a system diagnostic utility, a memory check, check for mismatched memory and try changing the video adaptors.  Apart from not really knowing how to do any of that, this is an HP computer straight from the store.  I have not messed with the insides at all (I did buy the parts and assemble my son's computer).

    It then asks me to disable recent hardware/software/drivers.  The only recent anything is Windows 7.

    Then it gives the technical information...

    ***stop: 0x0000007F (0x0000000F, 0x0001007A, 0x00000000, 0x00000000)

    Then it goes through the crash dump process.

    The screens that appear after restarting in safe mode with networking show this...

  • Please zip and upload the dmp files from the folder C:\Windows\Minidump to your Skydrive [1] (copy the dmp files first to your desktop, if you can't upload them) and post a link here, so that I can look at the dumps.

  • The minidump file shows an UNEXPECTED_KERNEL_MODE_TRAP (7f) stop error being caused by the CO_Mon.sys.

    The CO_Mon.sys appears to be a Symantec driver.

    Same error and cause in the following thread:


    Try updating the Symantec software.

    Also, I would recommend to update the Realtek sound driver and NVIDIA video driver.

  • So I attempted what you asked and it got me running in normal mode (not safe).  I ran norton updater and I have audio.

    The problem comes when I try to open either Internet Explorer or Norton.  It goes to the blue screen.

    Here is the dump...

  • Rather than just "updating" the present Norton version, uninstall the present version which is incompatible with Windows 7.

    Can you  uninstall Norton using "Uninstall a program"?

    There is also the following removal tool available, if unable to use "Uninstall a program":


    After uninstalling Norton upgrade to the latest version or use alternative software such as Microsoft Security Essentials.

  • Complete remove this yellow pest.

    Use Microsoft Security Essentilas instaed:


    Also install all Windows 7 Updates, because you still use the RTM:

    Built by: 7600.16385.x86fre.win7_rtm.090713-1255

    The last crash is caused by the parallel port driver which was unexpected unloaded:

  • I removed the "yellow pest" and everything has been working this morning.  Thanks for the help.  I don't know about the parallel port driver or how to repair.  I'll do the Windows 7 updates now.
