Motherboard LED on, but PC won't turn on?

[draptak]

Hi everyone,

I'm using a CX750M corsair PSU (only two years old), I had this tested using the paperclip, it powers on with the fan running.

I tried a new CMOS battery & gave it time replacing them to see if it solved the problem. No luck

I switched the Jumpers (CLRTC) back and forth vice versa, but no luck in that

I unplugged the RAM sticks and back, and I still used one RAM stick to see if it would turn on but no luck

I also tried to see if the Power button is the issue using the screw driver method on the two pin. but no luck.


Any solutions would be welcome, I'm thinking my motherboard might be dead? But the LED light is on and no fan runs nor sound.

Thanks

If it powers on with jumpering the pins in the 24 pin connector, but does not jumpering the power switch pins at the motherboard it does sound like a motherboard problem.
