BSOD diagnosis please?

Both BSOD's blame tcpip.sys - a Windows component associated with your networking stuff.
Since Windows components aren't usually to blame, let's start by updating your Realtek PCIe GBE Family Controller

Please go to this link and download/install the Win7 driver: Realtek

Also, I see that you have Alcohol 120% installed. It has a driver (sptd.sys) that commonly causes BSOD's on Win7 systems. Please uninstall the program, then use this free tool to ensure that the sptd.sys driver is completely removed: DuplexSecure - FAQ - Remove 64 bit sptd.sys

Finally, you have a driver dating from 2006 for your DigitalNow TinyTwin DVB-T Receiver. That MUST be updated as it's not likely to be compatible with Win7. See the list below for a link to more info:
OLDER DRIVERS PRESENT IN THE DUMP FILES
- Create a System Restore Point prior to doing any of this. DO NOT mess with the drivers themselves - leave the Windows\System32\drivers directory alone unless we specifically direct you to it!
- Please update these drivers from the device manufacturer's website - or uninstall them from your system. Reference links are included below.
- DO NOT use Windows Update or the Update Drivers function of Device Manager.
- Please feel free to post back about any drivers that you are having difficulty locating.
- Windows Update exceptions may be noted below for Windows drivers:

Hi John.

I appreciate your taking the time to help me out.

I have updated my network drivers from the Realtek site. The driver previously installed was the current one from my motherboard's support page.

Alcohol 120% was installed pre format, and I have not re-installed it post format. There was an orphaned shortcut in my Start Menu (from a backup) which I have deleted to prevent any future reference.
I do use Elbysoft's Virtual Clone Drive, although I don't believe it uses the sptd.sys driver. I have done a search of my C drive, and found no instances of spdt.sys

As for the AF15BDA.sys driver, unfortunately that is the latest driver that I have been able to find for my device, which is actually a Pinnacle Dazzle 71e USB DVB-T tuner. It is the recommended driver from the manufacturers site. If you have any ideas on this issue, I would be interested in hearing them.

It has been over 24 hours since I updated my network drivers, so far no BSOD. I will post back if it re-occurs.

Once again, thank you for your help.

Cheers,

Peter.

We ask you to update ALL older drivers because it's most likely that the older drivers are causing the problem.
But if you can't update that one (and you aren't getting BSOD's) then I'd suggest holding off on it for the time being.

Good luck!
