I tried to reset the cmos pullover on the mother board,?

for my personal view is normally when you transform your cmos battery you obligation to reset your cmos setting back. if the setting preserve on changing afterwards you need to update your bios or your motherboard have problem!!!
Make sure you have removed the jersey. Otherwise it will continuously reset. Also if you were at adjectives careless doing the reset you may enjoy damaged the board next to static, or a wrong connection.
Make sure that the jumper are set as they origanaly were. The BIOS will other reset it's self to the defalt of the BIOS settings. you then enjoy to have an OS on the PC to reset it to the date and time, this is usually done when you install a contemporary OS. but if you already have an OS on the PC next you will need to set the date and time surrounded by the settings menu.

Hope this helps.
