Windows 7: Windows 7 ultimate crashes randomly: Event 41,KernelPow

Updates:

Please see this events log.




It seems just before crash (3rd row), some error related to sptd, event 4 occurred. sptd seem to be related to Daemon Tools, which I cleanly uninstalled 3 days ago with Revo Uninstaller. No idea why it is causing problem now?

This post suggests to remove a particular windows update to solve the problem. But this update doesn't exist on my laptop.

Do you have Daemon Tools installed? Driver called sptd.sys (Scsi Pass Through Direct) comes with some third party virtual CDapps, most common is Daemon.

However, the 8 minutes time difference between sptd and hard reset tells it most probably was not the cause.

Currently I don't have it. I uninstalled it 3-4 days ago. I've updated STPD driver for windows 7 anyways.

That's what I thought initially. But time difference is 8 seconds not 8 minutes.

My bad! I'm sorry.

So it looks like it's the sptd.sys that caused the crash. Other members can have other opinions but to me it's quite clear: sptd crashes and 8 seconds later the whole system, there's nothing to see between these two events.

SPTD does cause a lot of blue screens. I would recommend removing it completely until this issue is resolved.

Since I updated sptd.sys from here, my machine is a lot stable. In fact no crash since then :) . I'll put my updates here if it crashes again. Thank you all for your help.

hmmm, I was wrong. Even after updating sptd.sys, it crashed. So now going with Jonathan_King's recommendation ie completely uninstall it.will post updates again.

ok, even uninstalling SPTD didn't work. Please see this log:



Strange thing is that I don't see any suspicious event around crash time (blue line)? No minidump was created. Anyone got idea?
