I am getting a lot of BSOD when my laptop is connected to an external monitor using a display-port cable.
The system is fine when I don't use a external monitor and use just laptop screen. External monitor is a Dell 30inch. I have tried different display-port cables, different monitors, tried connecting via vga...still get BSOD, so I am thinking the problem is more on the windows 7/software side rather than hardware.
I searched forums and have done the following so far:
1. Uninstall AVG free edition 2011 (as recommended in the forum, maybe switch to MSE after problem is resolved)
2. Upgraded network-gigabit driver directly from intel instead of Lenovo
3a. Upgraded Nvidia drivers directly from nvidia for Quadro 1000m (ver 8.17.12.7533 - 5/20/2011) - got BSOD within 30min
3b. Downgraded Nvidia drivers to version from Lenovo (ver 8.17.12.6696 - 2/2/2011) - still get BSOD but there is more time between BSODs.
I am using a lenovo w520 laptop, win 7 SP1, x64. 8gb memory, intel 510 solid-state drive, Nvidia Quadro 1000 and Intel HD Graphics 3000, No-Anti-Virus and running zone-alarm firewall.
The attached zip file contains
3 dump-files
3 Windbg analysis-files
cpuz and Rammon screen-shots
BlueScreenView screen-shot
Any help in analyzing the dumps and providing direction/clue towards a resolution would be greatly appreciated.
