Crossing my fingers and legs --- I installed it late this morning and didn't see any problem at all.
But, I've been working on the desktop comp all day other than the update(s) installations and a short bit of trying it, about 15 minutes maybe.
I'm really curious why some machines overheated during the firmware update.
Is there any way to tell if your fans are working?
I think there are two fans. Probably one sucking in and one blowing out.
Could there be a fan problem?
That's the only thing I can think of.
Mine sat here beside me and updated and rebooted twice during the process I believe.
