No updates were done just prior to this problem. It worked before I left for work and when I came home it started doing this. 

Don't know exactly what happened. Can only guess maybe a power surge hit, but it's plugged into a ups.

Unfortunately your going to need to call support.  More then likely the MB has had a critical failure and or the CPU has actually failed.  

Did this happen right after a bios update? 

Hello,

Please send me your service tag in a PM, so we can check the available repair options.

Same thing happening to me. So frustrating! Of course I'm 3 months out of warranty. This sounds like an issue with a lot of people!
