Low CMOS battery after 1 year?

Hi guys. Around a year ago, I bought a pre-overlocked haswell system from OCUK. It's been great so far, but over the last few days I'm getting symptoms of a what appears to be a low CMOS battery.

I first noticed an inconsistent system clock in windows. Upon booting into BIOS, the clock is incorrect there too. The PC itself is booting fine at the moment, but after a few hours, becomes unresponsive (task manager will take a while to load, and Windows Explorer will crash etc).

So, a couple of questions:

1) are these symptoms all possibly caused by a low CMOS battery.
2) Is 1 year an unusually short life for a CMOS battery (also, does overclocking affect CMOS battery life span?)
3) If this is not as simple as a battery, what are the other possible causes (dodgy mobo?, corrupt OS?, dying SSD?)

Basic system specs are in my sig, but more can be provided if needed.
 
I've never heard of this problem but it makes me wonder if I'm encountering the same thing seeing as though I'm having those problems sometimes as well and my system is just over a year old.
 
I would test without the ocz ssd attached if you can,if it still does it try with just one memory stick installed

cmos battery wont affect the stability of the pc,it just provides power to store the bios settings,you can bootup with no cmos battery
 
disconnecting the OCZ SSD is a definite possibility (it's my gaming drive) But could that, or RAM, be interfering with the BIOS clock? I've just tried booting into bios a few times, and the clock seems to be frozen at a particular time. (though I can manually update it).

im not sure,it could be a failing cmos battery but normally they last years

idk if faulty ssd or memory/setting would also affect the clock at startup,

cmos battery shouldn't make it freeze in windows though so id look into other things first

to rule out cmos battery causing the freezes bootup without it and see if it locks up again in windows (backup any bios/oc settings beforehand as it will wipe them)

any newer bios versions? maybe latest bios would help

you would need to copy your oc settings though
