Fail-Safe settings - boots work half the times so I am able to be on the desktop for some time.
The above settings are the correct ones, "optimized" settings are a form of overclocking which as you have found already causes instability.
Any more crashes since restoring the "fail safe" settings.
Download then run Speccy (free) and post the resultant url for us, details here, this will provide us with information about your computer hardware + any software that you have installed that may explain the present issue/s.
JAFYI: Checked another dump from Sunday Nov 1st which again points toward the CPU, there is an outside chance that the problem is driver related, Speccy may shed some light on if it is.
