Ehm, CPU is "central processing unit", a computer component. It does not have a light linked to its operation. If by CPU you mean the whole machine, call it "computer".

If that led is close to a symbol that resembles a lightbulb, then it's the power led, and tells if your computer is actually getting power or not. It should go on when you press the power switch and remain on until you shut down the computer.
If it is close to a cylinder symbol, it is the memory usage led, and tells if your computer is reading from its main internal memory device. It does blink randomly when in normal operation and if you don't experience other issues you can safely disregard it.

Other leds can indicate the wifi connection or whatever the maufacturer thought to place there, if it's not one of the above, try to describe it or find an image of it from google.

Please follow this tutorial to fill your system specs (step 7 to do it automatically), so we can know what is the thing you have in your hands. Without knowing more, help provided will be limited.

Those lights if I understand what your writing correctly is nothing you have to worry about as stated in the post above yours it only indicates hdd activity and memory, so they wont light up or blink if nothing is being used.

It sounds like you have a lot of background programs starting up or it could be a virus that causing the slow bootup, have you scanned for virus lately?

Actually, it sounds like there's a problem even getting the computer to reach the BIOS part of the bootup. Try using another outlet, it could also be a failing system board or power supply. Are there any noises or lights at all when you press the power button?
