Disk Management shows what I hoped. The event viewer HDD entry is not related to your main HDD. :) That's good.
Just skimming through your files now.
I see you have DAEMON tools installed. This isn't the cause of the problem, but something I will address. DAEMON tools is known to cause issue with Windows 7. The driver of DAEMON tools - sptd.sys, is the problem. From the Carrona Driver Reference Table:
|SCSI Pass Through Direct Host - Daemon Tools (known BSOD issues with Win7)|
So, let's uninstall it for good measure.
Uninstall the software using Add/Remove Programs. Once the program is uninstalled, run sptd.sys uninstaller
to remove the driver from your system. As an alternative, and the software I use myself, I recommend WinCDEmu - the easiest way to mount an ISO. And more...
I'm not seeing anything else in the logs of any real interest.
Here's what we'll do. Keep an eye on it. If it does it again, let me know straight away - reply to this thread as always. We will then proceed with a clean install of your graphics card drivers, because I feel that is the underlying issue here.
