BSOD -- seems okay but want to try nailing down the cause

Windows 7 machine. i7 4770. OS/apps on SSD. One HDD for data, and one SSD for data (added a couple weeks ago). All SATA. Very carefully and well maintained mission-critical machine.

While sitting idly, BSOD occured. It caused a spontaneous reboot. On Windows startup, Windows simply said it had not been shut down properly. All seems fine. CHKDSK and SFC showed all to be fine. (The only odd behavior so far is that the Error-checking "Start" button is frequently lagging up to 60 seconds before giving a response. I asked if that's normal in a different thread. Other than that, all seems perfectly normal so far.)

While I may restore from image backup to be safe, I'd still love to nail down the cause if that can be done.

The DM log file is attached.

Let me know if you need more.

Thanks!

F switch was implemented by virtue of my having run it from Windows via Drive > Properties > Tools > Error Checking > Check Now > and then leaving the default of "Automatically fix file system errors" checked on. R switch didn't concern me -- I didn't check the box to tell it to check for bad sectors (it's a top quality SSD that's one year old).

I run Symantec Endpoint and trust that to do all my malware protection. It's an enterprise-level solution I've relied on for years.

I do realize that it's not easy to determine the cause of a BSOD. Frankly, that's not what I really intended in the first place coming to this forum. I posted in the General forum asking if that lag after clicking Start for the error checking was normal. That's all I wanted to know, since that's the sole oddity I'm seeing after the reboot. But nobody wanted to answer that question there, and they sent me to here. (Go look. I had to be a bit firm yet diplomatic in re-asking them to just answer my question. I'm extremely experienced when it comes to troubleshooting and I know not to chase BSOD causes. I'll replace the machine first -- if it happens again, that is, since I know one BSOD can occur as a fluke on a perfectly stable system, and the only concern is whether it corrupted the OS. I'm mainly just looking to decide if I should restore from image backup. If anyone answers me.)

Thanks.

I absolutely do not have the funds to replace a machine on a whim. What I have even less is the time to chase down the possible causes of BSOD issues if they're recurring (let alone worry about constant image backups to restore if a BSOD corrupts the OS). I have a tech guru friend who said that a colleague does chase down BSOD issues and uses the DM log tool, so I thought I'd try it when it was suggested here.

As to my initial inquiry in another thread, I still haven't gotten an answer but I'm starting to think lags after hitting Start to run the disk check from within Windows are not uncommon at all (and don't indicate that the BSOD corrupted the OS), especially when it's being run on the OS drive and "Automatically fix file system errors" is checked on. It seems that during that lag time it's actually starting to run or at least initially scan the drive to see where it wants to go next -- eventually saying a restart is needed.

I appreciate the help very much... and the candor. Yes, if BSOD events occur more than once or twice, I will replace a machine.

And, yes, hanging out, helping, and making new friends here sure does beat the Facebook madness so many people obsess with.

Maybe you can do me a huge favor? In Windows Explorer, select your OS drive > Properties > Tools > Error Checking > Check Now. Have the first box checked (fix system errors) and the second one unchecked (checking bad sectors). Click Start, and count the seconds until the message comes up telling you it needs a restart to do that. Maybe cancel, reboot, and do it again? Maybe repeat a couple more times? I'd sure like to know the seconds it takes until the message comes up after a few attempts.

Thanks either way!
