I did mention that the Blue Screen is NOT the traditional Windoze BSOD. I'm currently trying like heck to replicate the problem, but no doubt it'll run fine now for days on end, now that I have asked for any help. As such there is no error codes at all accompanying the blue screen.
I recognise the issues of using Windoze 2008 drivers with Windoze 7. The choice of Operating systems was not mine, but the owner of the machine. I'm Linux through and through, but a Linux Option, hard as I have pushed, is not something the owner wants to entertain. Perhaps I should just install it and tell her is Windoze 11!!
The machine she bought from a weekend market stall, no doubt being 'swooned' by the stall owner, telling her it was great bargain, that it was the same as an i5 with lots of memory, and he would even throw in the video card for nothing ) Woot an nVidia GT620, could he afford it?? )
I'm the muppet who as her 'only trustworthy PC tech-friend' has been allocated the job of 'getting it going for her'
There appears to be nothing exceptional about the hardware, and therefore in theory at least, the generic driver should be fine. At the end of the day, she is a Silver Surfer, mind you aren't we all heading that way these days, and simply wanted a nice machine for doing online-sy stuff. Skyping family, the odd flash game, emails, photos organisation...and the list goes on.
Once the machine fails again, I'll photograph the results as well as the log entry I referred to in a previous messgae, and I'll post links to the imagery here.
