Well I believe mine just bit the dust as well. Suddenly yesterday it shut off and now it wont start. Get the 8.E. error (check CPU fan). I tried several different 3 and 4 wire fans to no avail, along with all othe the suggested methods to reset the bios to default settings.
I did order the $6 replacent bios chip to see if that will do the trick, but if not, I'll be RMA'ing it. Too bad too as it has been working flawlessly for quite some time.
