BSOD's are complex creatures and it's not always simply a one-step fix.
Running Driver Verifier was a good move, let's hope that it was SmartDefrag that was the problem.
Once you turn Driver Verifier off, wait and see if it BSOD's again (or if you get the "driver recovered" error again).
So far I've still got driver verifier running. Had one BSOD but that was when I tried to use WinCDEmu. My PC apparently hates mounting programs. I used the portable version though, so when I rebooted the issue was fine. It gave me some kernel handle exception error of some sort but smooth now. I heard that it's best to let verifier run for 36 hours at least so I figure I'll go ahead and do that. Other than the WinCDEmu issue and the SmartDefrag, everything is working fine. I even re-installed PhysX to test with the driver verifier and so far, smooth as a whistle.
The 36 hour rule was made up by me ( Driver Verifier Settings ). It was my best guess as to how long it should take to get a BSOD that was Driver Verifier enabled. You've already got that, so there shouldn't be any need to continue to run Driver Verifier.
Just turned off Driver Verifier. Sorry the response took so long, didn't notice the email about your response. Since I haven't had any issues since I got rid of the Smart Defrag program, I'm hoping the PC is fixed. Though that makes me curious, I've used Smart Defrag for years, why would it suddenly become an issue when I install a new graphics card and drivers for that card? Just happened that the card's and program's drivers didn't like each other?
Here's my theory (well 2 theories actually)
1) I wonder if the Smart Defrag driver had a little "bug" in it that lay unaccessed and undiscovered for years. It took an update to Windows to access that little bug and that made the bug's presence known.
2) I wonder if there's an interaction between the graphics drivers and the Smart Defrag drivers (sorta similar to what I thought above). That would mean that a new function in the graphics driver accessed the "bug" in the Smart Defrag driver (or it could be the other way around with Smart Defrag accessing a bug in the graphics driver).
Why do you always say install service pack 1, if you have updated windows already, why do you need this?
Service Packs are needed because they also contain fixes that you don't get through regular Windows Update channels.
Good news. Since my last post where I turned off driver verifier, so far, the computer has ran seamlessly since. No "driver has recovered" crashes, no black screens, no freezes, no lag spikes, and -yay- no BSODs.
