No power to front panel (power supply does work on board light on mother nboard is on wghen cable is plugged in

Answers :

What you describe sounds very much like a power supply failure.
\015\012If you have recently been in the computer double check all connections coming from the power supply to the board
\015\012Because computer power supplies produce many different voltages it is always possible for a small led on the motherboard to be lit.
\015\012Also turn off and disconnect the computer for at least 15 minutes.
\015\012look at the fan carefully as you insert the power cord.
\015\012If it tries to turn at all but then stops suddenly then that is another sign of a dead power supply
\015\012You may need to use the power switch on the rear to try that test also but if you get the same result it is usually conclusive.
\015\012removing a power supply is not too difficult, if you feel confident enough
\015\012then remove it take it to your local computer shop and ask them for a new one but also ask them to supply one that is slightly higher rated than the one that is broken eg if yours is a 350W try go for a 400W or 450W
First pull out cmos cell from motherbord for 10 minutes .So all settings are defaults becaseu some times rong settings in bios create this problem.
\015\012Then check your cpu power supply unit. It is called SMPS is it working or not.
\015\012Try with other cpu SMPS unit.
\015\012Refix RAM memory to.
