When I switched on my PC, the power (green) and HDD (Red) light don't switched on, no display on monitor.
DVD Writer has power. I can also see light on LAN power connector.
I didn't install any software or hardware. The day before it was working fine.
I have verified Hard disk, RAM, SMPS, all are working fine. I also reset BIOS by replacing CMOS.
Please help me in identifing defective component.
Is it my motherboard( D945GCCR ) or issue may be somewhere else?
Use a volt meter and check the four pin that supplies power to the CPU and see if you have 12 volts there ??
