My PC seems to keep turning itself on after I power off and apparently a common issue is that you need to update your bios.
My Motherboard is GIGABYTE GA-78LMT-USB3 AMD 760G (Socket AM3+) Micro-ATX Motherboard. Using System Tools I've found out that my BIOS version/date is "Award Software International, Inc. F2, 10/08/2012".
I think I've discovered the correct motherboard on this site
This is how far I've got - unsure what I need, or should download from the options there (and even if I have the right site). Obviously I'm really cautious about all of this so would really appreciate any help or advice?
