I wasn't sure where to place this thread. But today, for the third time within a week period, I've had to reset the CMOS to get my computer to turn on. Then go into BIOS and reset everything. Otherwise, when I turn my computer on, it turns on but the computer won't POST; it just sits there.

Any ideas as to why this is? Do I need a new CMOS battery?

What are your full system specs?

I would change the battery.
I've had PCs do that many times with a bad battery.
I even have two PCs that still do...as the batteries are soldered to the MB and I'm leery of changing them...as the machines they run are critical and make our company a lot of money and I don't care for that kind of risk.

replace cmos battery, you can literally buy it even on gas station. The most common type used since early 2000's is CR2032. It'll set you back around 2 dollars.
