Default case fan stay on

Noticed the other day that my kids computer after turning it off the case fan stays on, but will turn off if you hit the power switch on the power supply. But if you turn the power supply back on with the main switch the computer will boot up. When you do power the computer down it does turn off, the monitor turns off but the no video signal is on. Do not know if this will be a motherboard issue of power supply. How do test it?

antec 500 watt power supply

How are you turning the computer "Off" If you're just holding the power button it could be going into a sleep or hibernate mode, cause the fans to stay on. But if you turn the power supply back on with the main switch the computer will boot up.What's the main switch? The switch on the Power Supply or the normal button? When you do power the computer down it does turn off, the monitor turns off but the no video signal is on. Do not know if this will be a motherboard issue of power supply. How do test it?
I'm confused. You're saying that when you turn the computer off it shows on the monitor no video signal. If that's the case that's normal, because the computer is off. Actually the monitor may not turn off, it might just go into a standby mode. It only turns off when you physically hit the power button on the monitor.

when the computer first starts up enter the bios(press witchever key the black screen instructs you to enter "setup") and in your power settings configure each event in the list to initiate the power state that you want

The computer is always turned of using the operating system which is XP.
And of course turned back on by using the switch on the front of the case.
After the computer powers down the case fan and the power supply fan stay on. In order to turn off the case fan and the power supply fan you need to turn off the switch on the back of the power supply. Now when you turn the switch on the back of the power supply back on the computer will boot up, which should not happen. The computer does work normal. Did notice that the wireless signal has been sucking lately.

And after you do power down by using the software. The computer will start up if you use the switch on the front of the case.
