my girlfriend just built her new PC on her own. Everything is fine except that the motherboard (890GX Pro3) doesn't remember settings, boot preferences and datetime every time she turn the power supply.
Before it had problems when turning on, the debugger said 00 and didn't even began to boot. An update to the Bios solved it but it didn't worked for the clock and preferences.
I'm pretty sure the problem is the battery of the motherboard, but i would like to ask you what could be the problem, and maybe a tutorial to replace the battery.
Thank you in advance
