what motherboard bios are you running / full system spec might help as well
what version of windows, in search type 'cmd' and 'ver' to get that information.
did this just happen at the time you updated the driver, did a driver rollback allow it to work ?
edit. The EATX12V (8 pin power above the cpu, on the left) is that plugged in (if you have psu where it can be disconnected check both ends) ?
