BSOD BugCheckcode 0x000000D1

Right, did that, restarted, and upon restarting windows started to install new driver software. As soon as I got the message that the hardware was ready for use: BANG, BSOD!

Started windows again normally and checked the device manager and I am now on driver version 2.0.0.74!!!

I tried updating by browsing to the folder on my computer but windows told me my driver was up tp date.
I tried updating by automatically searching for new drivers and windows has just upgraded me to version 2.0.0.75

I seem to have gone backwards rather than forwards :S

The automatic update option is now also telling me that my drivers are up to date...

Right, I unistalled version 2.0.0.75 and windows automatically installed 2.0.0.74 again --> BSOD

Then after it restarted I tried to uninstall version 2.0.0.74 but there was no box to tick, so this software cannot be deleted. I clicked ok, it uninstalled, the adapter became invisible and when I clicked "scan hardware changes" the adapter reappeared and windows automatically reinstalled driver version 2.0.0.74 --> BSOD

Here we go, new minidump files and system health check

I am currently installing windows updates and need to restart. Be back in a bit.

Thanks again for your help and for putting up with a numpty like myself.

Installing yet more updates, I only just installed and it's now come up with 9 more updates. Will let you know once it's done.
