My problem is when the power button is pressed nothing happens. The green light is on steady on the power supply. The power supply fan is running. At the present time, I have the computer completely disassemble and hooked together on a table. I have the power supply 24 pin connector connected, also the 4 pin. The HD, Floppy, DVD and CD are all disconnected. The monitor and keyboard are connected. The ram is installed. The power button is connected.
The green LED on the power button does not light at all. Fans do not move. The voltages out of the power supply are 3.3 V, 5.01V and 11.69V. measured at the board. I noticed the CPU heat simk was warm. I have followed the instructions given to rest the CMOS. I have swapped the memory board one at a time.
Nothing has helped. I would appreciate any help available.
