I just built a pc a few days ago and the motherboard was oredered a week or so ago. I think my cmos battery may be broken or faulty.

Motherboard: M5A97 R2.0

Basically when i shut down my PC, it is a windows 8.1 if that means anything, and then if i switch off the main switch that powers a cable/power strip to all plugs that are related to the PC, and then later whether it is a few Seconds, minutes or hours later i turn the main switch on and turn on my PC, it stops at this "American megatrends" page telling me exactly "Please enter setup to recover bios setting. Press F1 to Run SETUP". And from the bios settings i can choose "boot from" and press my ssd that has my OS installed or just choose "exit and save".
BUT, if i turn off my PC and leave on the main switch plug and later turn the PC back on by pressing the power on the tower only this time, then my PC boots straight onto windows no problem.

Maybe you guys know why this is happening? Is it the CMOS battery? Maybe its faulty? My mob9o is new though. My PC runs smoothly too, i ran battelefield 4 on ultra/high with cpu temp 50-60 and when im just browsing the web its 29-35. Mobo temp is usually 24-28.

I asked a couple of people who have built PC's before, PC technitions and even a computer programmer, and after a lengthy talk about my pc, most of them ended up saying its the cmos battery probably, whilst others say they don't know because they'd have be there on my pc. I asked sime is it a faulty mobo they said probably not as everything is working.

Please, what do you guys think the solution to this problem is? Is it even a problem - maybe?

Thanks a lot for anyone who read this and tries replying.

***SOLUTION - I FOUND OUT THE JUMPER CAP WAS MISSING FROM MY MOTHERBOARD, IT FELL OFF WHEN I WAS PUTTING MY PC TOGETHER THUS CAUSING BOOT FAILURE, YOU CAN ORDER THEM FROM AMAZON, LUCKILY I FOUND MINE IN THE BIN - SOLUTION*** << For those who have the same problem as me

If you replace the cmos battery and it still loses settings when you disconnect from the mains, motherboard bios chip is bad and RMA the motherboard.

I found out that the Jumper was missing form the motherboard, when i put it back on the PC was working normally.I never knew what they were when i was putting my PC together or when learning about PC building. Luckily still found it in my bin lol (it fell off while building, i thought it was just a protective cap plus i never saw where it fell off from).
