When i start my computer always getting american megatrends

Specs: Windows 7
Like about a week earlier, when i started my computer it goes to American Megatrends and cant open so i sent it to repair and they just change the battery for me. But when i take it back also get the same problem but this time i just have to press F1 into BIOS, change the time and date and quit it and can in the window already, and i have to do it everyday since it back. I ask my friend and he said just buy another battery and change it, does it mean i have to buy another battery and change it?(When sent it to repair they just changed one for me so i'm curios...)

Anyway, here's the detail of my American megatrends page.Hope it could help or need something else?

It sounds like the CMOS battery that the repair shop fitted may have been partially flat - - less than 3 volts - - this can easily happen with batteries that have been left on a shelf for many months.

I suggest you buy another CMOS battery from somewhere else.

Here are pictures of the ASUS B85M-G motherboard. The battery is almost in the center of the board. It's a lithium coin style battery, probably a CR2032. They have about a 10 year life expectancy.

Are you SAVING the changes when exiting the BIOS screens? If not, then the changes are discarded.

Press F10 when exiting and follow the prompts.

Yes I did click that save button but shows nothing changes and auto restart my pc but it did change after that. But the next day still the same, need to change the time and date again.

If the date & time resets after killing all power to the computer & then restarting later, the CMOS battery is probably bad. A restart from Windows without killing the power probably won't cause the date/time to reset. Take out the battery & test with a voltmeter. It should be 3V or very close to it. If it's not, replace it. CR2032 batteries can be purchased just about anywhere batteries are sold - drug stores, Walmart, etc. Dollar Tree sells Sunbeam CR2032 (2-pack) for a buck.

CR2032's typically last up to 10 years BUT if you unplug the computer or power off the power strip then the battery is using juice just to keep the settings locked in. This is why some people get 9 or 10 years and others get 1-3 years on them. Keeping power to the MB keeps the battery from draining slowly.
I agree that they either did not do what they said or they put in a new older battery (or an old battery they thought was new or good) that was past its shelf life (many years).

You have to be a little bit crazy to keep you from going insane.

If the battery is OK, check the holder if the battery is firmly in place, usually a spring-type bevel pressing the battery down in the holder.

So yesterday I bought 2032 battery in the drug store and change it but still does't work, (I bought 2 batteries but 2 also din't work.) I already check the holder, it's firmly in place. What if its not the battery problem, maybe something else?
If I change the date and time everyday will my pc be in any harm?Just asking cuz i'm afraid so.

Changing the date and time won't cause any problem.
Not changing the time and date to stay current, or at
least to keep moving forward in time, could cause some
minor problems, but probably nothing to worry about.
The date and time stamps on your data files will be
wrong, as well as logs kept by Windows. If you are
okay with that, nothing will blow up.

And it is not in the reversed position? Usually the + sign of the battery on top?

Is there a jumper for resetting the CMOS data? if so is it in operational position?
