Bios getting reset everytime.

[Purgatory420]

Motherboard- Gigabyte 1155 rev 3

CPU- i3 3220

PSU- 10 dollar 250 W frontech

OS-  Windows 10 pro trial

Pc keep getting reboot and I have to select "load optimized settings". I have replaced the CMOS battery last month. I purchased the motherboard last month(it cost around  35 USD)and it's a used one.

I'd take the battery out and test it, you could've just gotten a bad battery (not likely but possible). If the battery is still good, there might be a scratch on the motherboard that broke the trace for the CMOS battery, causing it not to work.

I'd check the clear CMOS jumper.  On many boards those do not even ACTUALLY clear the CMOS, the 'CLR' position does nothing, but the other position allows the jumper to bridge the pins which allows the 3.3v power to reach the SRAM and RTC.  'Switching The Jumper' doesn't 'jump' anything, it just literally cuts the power connection, the 'CLR' position is just a safe place to not lose the jumper for 15 seconds.

Solved a 'bad' CMOS on an X79 board, the jumper was just broken and never bridging the pins in the default position, so the SRAM/RTC never had power from the battery ever.  New jumper, problem solved.

But it ran fine for before. Shouldn't that junper thing had cause the problem before?

Look, if you're having CMOS issues, and you want to argue against checking the CMOS jumper as part of your troubleshooting process, I dunno what to tell you.
