Main BIOS Checksum Error

[Niketan]

I had a PC running daily , then I didn't use it for a couple of days and now it shows an error like this :
Main Bios Checksum Error . . .
Retrieving Recovery Source from HPA . .
Retrieving Recovery source from backup Bios . .

And then it shuts down and restarts again with this.
My specs are : (Pretty Old PC though I know )

Gigabyte G31M-ES2L Motherboard
Intel Pentium Dual Core 3.00Ghz Processor ( I don't remember the exact name )
2 GB RAM ( 1GB × 2 )
WD 320GB HDD
Windows 10 - 32 bits

I tried clearing the CMOS by both removing the battery and the CMOS jumper. It did work when I removed the battery for like 1 day . But When I inserted the battery , it would still shut down after booting up ( sometimes in Lock screen and sometimes on l the desktop ) .
I changed the CMOS Battery but the issue persist.Tried replugging everything. I haven't updated the BIOS. I am afraid to do it as it sometimes screws up whole thing. I have a strange feeling that any Virus could have altered the BIOS . I can't get into BIOS settings . Is there something I could try or is it my Motherboard dead . Please let me know if you can help let. Thank you.

i dont think virus could create problem in bios virus are for OS only not for board flash memory.
you can try updating the bios when you already have issue

Ok . I will update the BIOS and try. But I haven't done it before. Should I download the Update and save it to USB drive or CD drive and the insert it ? Because I can't get I to Q-Flash ! Thanks for the reply .
