Crash with loss of video

Hello,
I have a computer that will initially boot up, load windows, and allow you to log in, but shortly after crashes with a blue screen that doesn't allow me to catch the error because the video cuts out. After this crash, the computer will no longer display video, either out of the video card nor the built in graphics.

Although I was not able to catch the screen, I have recovered the memory.dmp and I have use WinDbg to decode it. Here are is what it says:

Code:

Any help would be greatly appreciated!
 
Re-install Windows, after formatting the hard drive, because you can't get in to Windows to fix anything. The re-install will let us know if there is a hardware failure
 
If it runs well after a fresh Windows install, when does the BSOD start? After you install Norton?
 
I've resolved the issue with this customer's computer. However, nothing had been changed on this computer in months, and it had not been started up until a few days ago. The BSOD happened with the original installation. Norton was previously installed and working for months with it installed.
 
Norton sometimes interferes with the Windows firewall and Windows Defender in Windows 7. There is no need to use 3rd party protection software... After applying all the Windows Updates, the Norton instability will suddenly appear, either immediately or after a few months. Microsoft Security Essentials is free, and you can guess that it doesn't interfere with Windows 7 at all. Have you applied all the Windows Updates, including all the optional updates?
