Just crashed as I was tidying up my mail. On restart it said problem with faulty driver which needs to be replaced. Now in safe mode.
Frequent BSOD crashes

To run chkdsk, run it from the command prompt, not directly. From the start menu, enter "cmd" , right-click on cmd.exe, and select "Run as administrator". In the console, run chkdsk /r. It'll stay open that way.
The Z drive is indeed a network drive; if you don't want it, you can right-click on it in My Computer and select "Disconnect network drive".
Go ahead and disable Driver Verifier for now; that will at least reduce the frequency of the crashes until we get them figured out for sure.

How do I disable driver verifier? I am in Safe Mode on PC (typing this on Mac, whilst running Malwarebytes full scan again). Will leave PC in safe mode overnight if it stays open till I go to bed. That way I can see if it has stopped overnight. Scan finished, with no problems reported now. CHKDSK also reported no errors.Last edited by Bob Pickering; 03 Apr 2012 at 08:05. Reason: updated

To disable driver verifier, open a command prompt as administrator ("cmd") and enter verifier /disable. Driver Verifier doesn't run in Safe Mode, though, so you don't have to worry about that until the morning.
Hope all goes well, we can pick up when you return!
EDIT: Just noticed post 29; be sure to also run SeaTools on your main C drive.
Since it seems the problem may be software-related, perform a Selective Startup in Safe Mode. Disable all 3rd-party services and all startup items, and boot back into Normal mode.Last edited by Jonathan_King; 03 Apr 2012 at 13:51.

Hi Jonathan. Am back, just briefly. Cannot disable verifier in method described. Tried with spaces too, but still says ignoring unexpected parameter. Did have a couple of crashes in safe mode, but far more when I reverted to normal. One of the error messages suggested might be a problem with bluetooth usb for keyboard/mouse. When I installed software for logitech, the combo drivers seemed to have a different model mouse (more buttons/wheels). Have had problem at times when it somehow changes keyboard language, and some upper case keys don't function as they should, e.g. @ comes out as #. Reverts to being OK when I change back to English(US).
Just crashed again. Attaching perfmon report.Last edited by Bob Pickering; 04 Apr 2012 at 21:54. Reason: new attachment and explanation.

I'm sorry...I gave misinformation; the correct command to disable driver verifier is verifier /reset, not /delete as I had posted.
I'm still seeing pfc.sys trying to load upon boot. Have you figured out what program that belongs to? If so, uninstall it. If not, start by disabling MacDrive 8 from starting automatically.
Again, try that Selective Startup as well.

Jonathan: I hope I am uploading correctly as a new post in the thread. Let me know if not.

Jonathan: Did the MacDrive8 deactivation. Said restart needed, and as soon as I did that I got BSOD crash. Have done verifier reset, and restarted again in normal mode to see what happens . . . Isn't it past your bedtime in NY? My phone tells me it's after 11pm Wed. It's 12:48 pm Thurs here.

There seems to have been a couple of errors with drivers for my second optical drive
but all seems ok when I view device manager.
Is this the error you are referring to?[extracted from event viewer logged today 12:16pm)
\SystemRoot\SysWow64\drivers\pfc.sys
000000000200300000000000240400C0000000006C0300C000000000000000000000000000000000
Not that it means much to me.
The Optical Drive error looks like: The driver \Driver\pfc failed to load for the device IDE\CdRomHL-DT-ST_DVDRAM_GH22NS50________________TN03____\4&f58e17d&0&0.3.0.
