Thanks for the response it has given me a couple of good suggestions to try, in the meantime I have a few bits of info:
- RST
Drivers I am using are 10.1.0.1008
- Chipset
Drivers, yesterday I installed 9.2.0.1030 which also cured the PCI Simple Comms Device issue. Sadly I got another BSOD after I had done this as I thought this could have been the cure.
- Zonealarm, I'll give this a go although I like being able to stop programs accessing the web without my knowledge. Feels kind of safer.
- MSI Afterburner, OK will uninstall although I am not running anything.
- 650W PSU. If the other things fail, I will give this a try. Crashes are occurring when I am not loading the system at all though (surfing web, using word). I can game quite happily and it won't necessarily BSOD. I would expect PSU issues to occur more when under load.
- ctac32k.sys is the latest
driver for the Soundblaster X-Fi Gamer on the Creative website. It is part of their 2_18_0015 suite of
drivers. If you could suggest a more up to date one I will try it.
- Malware. I've run AdAware, MBAM, MSE, Avast, AVG (AVG and MBAM from my old OS install on the raid) and BitDefender on-line scan. Thus far no malware or viruses have turned up.
- Wireless
driver athrx.sys. I'm using an Abit Airpace PCI-E wifi card. This doesn't have Windows 7 drivers so after a bit of research on the web it is Atheros chipset so I installed Windows 7 Atheros AR5006X
driver which worked fine with my old 'raid' OS. Again, I will remove as last resort.
It's a shame the minidump isn't a bit more conclusive. When it does BSOD I also get a Kernel-Power (Event ID: 41) critical failure logged. Can I get any closer to the root cause looking at this in more detail?
Once again, thanks for the help, fending off a re-install would be great if possible.
