How can fast startup and this northbridge failure thing connect together, this doesnt make sense at all!?!
I have no idea either. But I'm having the same experience so far! I disabled fast startup, the computer now takes a little longer to startup, but this is the longest period without the problem (23 days [my use is not intense]). The previous record had been 15 days.
I'm also experiencing this issue and it has been rather annoying. Computer shop ran stress tests on it for 2 days, to no avail. Was told to change the outlet I was using because it could have been faulty but that did nothing either as my computer restarted again today. Right now I, as all of us in this thread are, am pretty desperate to find an issue that doesn't have to do with having to upgrade to a whole new motherboard, RAM, and CPU.
I'll try the fix and I'll keep an update on how it works out for me. I'm glad theres an active thread about this!
