I've read reports about having issues with 2 sticks of RAM. It was much more stable with 1 and didn't crash once when I tested it
Did you try a complete uninstall of Intel® HD Graphics drivers before updating?
Did you test the system in safe mode or reset BIOS settings back to default?
The file luafv.sys appears to be referring to LUA File Virtualization Filter Driver.
It may help to run the Windows* System File Checked (sfc /scannow).
The graphics was already up to to date so I didn't need to upgarde that.
I've updated BIOS to v30 and that seems to have made it more stable. I'm still getting MCE crashing from unknown errors but no BSODs at the moment.
System file check was clean too.
Thanks for your suggestions
