Thanks for reply.
It should have been a standard kernel memory dump in default location and used grab all (run as admin) then zipped it, don't know how its corrupted.
I think this may be a hardware / heat issue CPU or RAM. I've kept it cool and not connected the power adaptor and am now unable to get it to blue screen, nearly completed a full scan but about to run out of battery - it would crash within 10mins every time I tired a virus scan at least 6 BSOD crashes yesterday. If I get another BSOD I'll grab again and repost the new zip file.
