Windows 7: BSOD with SLI both playing games and general multitasking on Win 7

My pleasure.

It does indeed "appear" to blame the video driver each time, but it has two different error codes meaning either the video driver crashed in 2 different ways, or something else is making the video driver crash.

Unfortunately verifier doesnt seem to be enabled on all 4 of these. Can you type erifier /query and note if it says it is verifying the nvidia drivers?

It should not return "no drivers are being verified".

Other things that can be causing/contributing

1-sptd.sys
Please remove any CD visualization programs such as Daemon Tools and Alcohol 120%.

They use a driver, found in your dmp, called sptd.sys, that is notorious for causing BSODs.

Use this SPTD uninstaller DuplexSecure - Downloads DuplexSecure - FAQ

when you're done you can use this Freeware:

MagicISO Virtual CD/DVD-ROM (MagicDisc) in its place



Using MagicISO to create ISO image files

I typed verifier /query in cmd and it did indeed return that no drivers are being verified.

Also I've uninstalled all burning/ image mounting software and the same crash and BS errors still occur.

Thanks.

I didnt think it was enabled. Please re-read the instructions and enable it. If you have BSOD's upload the the DMP's

Ah, obviously it needs to be verified for you to see in the DMP file. But the only reason they're not verified atm is because I've deleted by current settings on DV because that's what the instructions state:

"Reboot into Windows (after the crash) and turn off Driver Verifier by going back in and selecting "Delete existing settings" on the first page, then locate and zip up the memory dump file and upload it with your next post."

But like I said, after enabling it I can't boot Windows. It just blue screens and I can't get into safe mode because f8 just brings up boot options for my mobo (I could change the hotkey?). So I end up using the Repair System disc I created but it can't repair Windows and I have to system restore which means I restore the system to a point in time before DV was enabled.

Thanks.

EDIT: This has been solved, with this board you have to be extremely accurate in pressing f8 otherwise the mobo boot options appear. I'll try DV again.

~Latest: Went through all of the step-by-step instructions which are not hard at all. Restarted my computer for the changes to take effect I then tried to boot windows and crashed at the logo screen, I then booted in safe mode which worked. BUT I can't enable SLI because the NVIDIA control panel isn't there in safe mode and that is the only thing that makes me BS. AND when I was in safe mode I typed verifier /query in cmd again and it should be enabled right? But it returned that no drivers were being verified. In my eyes from that there is no way round finding out what driver it is now? Unless there's another way. I'm really considering a clean install of Windows 7.

Until you remove Daemon Tools and/or alcohol 120%, you will continue to get crashes on startup with Verifier running. Both of these are known to causes crashes with Verifier enabled.

Do you still need help tracking down the culprit?
