This is the battery you are looking for.
Just about any computer shop, Radio Shack or Watch repair shop would have the correct battery for you.

Just make sure you unplug from the wall and you touch bare metal of the case before you reach in. Take the battery with you as most places will recycle and they will have a cross-reference chart. It is typically a CR2032.

Make sure the the interior is clean of heat trapping dust before you close up. After you install the battery and reconnect to power, boot immediately into your BIOS Setup Menu to set your date and time, and reset any custom settings, like boot order, you have as your CMOS will be reset once the battery is removed. Then be sure to "Save" and Exit.

Unless you are having a over heating problem with your cpu then I myself would not worry about it.

Unless it dries out and you can actually see it flaking then it is never recommended to just change it.
Depending on the amount of time you have your system actually running everyday will also be a deciding factor.
In my case my systems run 24\7 and in 15 years I have replaced thermal paste only once.

Most computers use the same flat battery. Cr2322 i believe it is.
If the thermal paste dries out then the best way to resolve it is to start the system for a few minutes and let the paste warm up. Then turn the system off and disconnect the power from it.
Gently but firmly you will need to remove the Heatsink and fan assembly from the CPU. Clean both the heatsink and CPU of the old thermal paste.
To reapply paste you would put about a drop about the size of a pea on the heatsink and spread it out to cover the area completely that contacts the CPU. Check the fan and heatsink for dust and if needed use a can of compressed air to clean them out.
Reattach the heatsink and fan assembly to the CPU making sure to plug the power in for the fan.
Reconnect the power to the system and start the system. Check to make sure the fan is turning correctly.

Now one more question my friend, u see ive just noticed something on my motherboard right on the left hand side from the cmos battery of course i see that there r 2 little devices one of them turns on when the machine turns on and the other when u r using ur system or something like that the thing is that this little device the one that turn on with my computer its alway showing a red light its been always like that since i purchased it from newegg.com so yesterday night i was doing a little research myself about this particular device and i found out that it could be the battery wats causing this red light behavior on the other hand it could be that my motherboard is malfunctioning already and i would need to replace it for a new one from EVGA, so i dont know wat else to do my friend i just wanna find out wats causing that red light

You NEVER have to replace the thermal interface material (TIM) unless you remove the heat sink fan or break the bond between the CPU and HSF. It does not wear out. But if you remove the fan assembly, or twist it and break the bond, then you MUST completely clean all the old TIM and properly apply a fresh new layer. See my canned text on TIM here.

And BTW - typing in ALL CAPS is frowned upon. It is harder to read and is considered SHOUTING - and no one like to be shouted at. Use all caps for emphasis only.

And the battery is probably a CR2032.

with the description of the "two devices" somewhere in your computer, no one is going to be able to answer your question.

if you're talking about a red light on the motherboard that comes on when you plug the computer in or turn the PSU on (if your PSU has a switch), then that's normal, it's the light that shows that your motherboard is getting power from the PSU, if you DON'T see that light, then you've got a problem
