If you have no joy with that let me know and I can try again (not 100% positive it was successfully uploaded) or alternatively upload the memory dump.

The MB is an Asrock 775i945GZ and the Hard drives are both pretty modern SATA ones.
What do you suggest next?

I've had quite a few problems with hard drives before,....they never seem to last longer than 18 months or so, often report that they are predicting failure (even when nearly new) etc.
I've tried different cables and SATA ports when I've had those problems before and they've not made a difference and I've ended up buying new hdd's. But I didn't think the problem was related to the interrupt problem....
If I recall a long time ago I had the same problem with interrupts in XP and Microsoft eventually issued something but I cant remember what, that fixed it. It may have been SATA driver updates or something. And the problem only came back when I installed Windows 7.
Also I have tried killing processes one by one to see if the problem goes away once it has started happening but it's impossible to do the other way round because the problem is not there all the time. You can't do a clean boot, wait 48 hours or more then start a driver, wait 48 more hours start another etc.

Also programs like Paragon Partition Manager and there was another I had installed (name escapes me) for drive imaging for backup purposes.

Then I didn't want to speak too soon, I was waiting, and it got close to the point where i was going to say you had fixed it... But then unfortunately just now the problem re-occurred.
I will now try to disable it completely and try again but in the meantime I have uploaded a new etl file for your perusal. As far as I can tell the problem is the same..."UNKNOWN". Would you like to view the memory dump I saved before?
Here is the link for the ETL file:

As far as I am aware I already have the latest sound drivers available for my mb with my OS according to the Asrock website.
Do you have any other suggestions?
Thanks, really appreciate the help.
