PC startup problem

[ARJOT SINGH]

Hey guys
I m facing a weird problem. Whenever I start my PC, I get a error message that says
"CMOS settings failed
press F1 to enter setup
press F2 to use default settings"
This happens everytime I start my PC & then I have to change the time and date of the system in BIOS. Also I have to change my first boot device to HDD from floppy drive even when I don't have any floppy drive in my PC.
I have done some basic troubleshooting like removing & reinserting my RAM & CMOS battery. But to no avail.
Please help.
Thanks in advance.
