Motherboard Fried? Or What?

[CarbonFibre]

Ok, so i leave my computer on all the time, but recently, i came back from a small trip and my monitor did not detect a signal. i checked my mouse and my keyboard and their lights weren't on. when i thought that it may be the connection mucking up, i tried to restart it, but it didn't turn on. my motherboard is a ATI 9950 Black Edition i believe. if the power supply matters it a 600w OCz. i don't know a lot more so i cant tell you. but is it a motherboard issue, battery issue or a power supply issue?

Check the voltage of CMOS battery. Determine positive and negative polarity by the plus or negative sign engraved on top of the battery. Set the voltmeter to the lowest range above 3 volts. Apply the positive multimeter lead to the positive side and negative lead to the negative side. Read the voltage. If the meter reads below 2.5 volts, consider replacing. If it reads below 1.8 volts, replace the CMOS battery.

Ok. Is The CMOS Battery on the motherboard? i assume its not the lithium battery.

I may buy one but only after i test the other motherboards with their batteries.
