:IF HAPPEN AGAIN:
if this problem happen again after you turn off your computer and turn on again. maybe you need to replace a new CMOS BATTERY.
cmos battery keeps your computer up to date even your PC is off.
if you dont have spare CMOS BATTERY.
go to meat shop and ask if they have a CMOS BATTERY (just joking)
go to any computer parts and accesories store and buy.
its around 25 pesos each.
place cmos battery as same position like in the picture below.
