CMOS batteries repeatedly going bad

[Rahul Kavlekar]

My PC components are :-
SEASONIC S12 520 PSU
amd sempron 145 (2nd core unclocked and overclocked to 3.2ghz) (amd athlon x2 4450e)
seagate 40 gb and western digital 320 gb harddisk
msi 760 gm p33 motherboard

Almost a year ago my CMOS battery stopped working.So after some months I replaced it..But after working properly for about a week it went bad.I again replaced it with new one but again it stopped working..I cant figure out which PC component is causing the problem..
