I looked this up in the event viewer:

The computer has rebooted from a bugcheck. The bugcheck was: 0x00000116 (0xfffffa800a2414e0, 0xfffff88010187cf8, 0x0000000000000000, 0x0000000000000002). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 101110-23322-01.

I do remember the DLL was one of the NVidia ones, although I cannot remember which one now.

Trying BIOS change again, will let you know how this goes! Two clicks huh... ok! :-)
