Wattage is HIGHER 480W—>550W
I have not changed any other hardware prior or during to this malfunction. The system is identical to how it was yesterday at 5:00 PM. It has worked flawlessly up until now, save the last time the p/s died (was 300W, upgraded to 480W now 550W)
At some point last night there was either a power outage or a windows update which caused the system to shut down.

DOES the log file show anything regarding the Avast driver it hung up on? That is why I am here in the Avast forum.
This morning I started it up and the circus began.
