programmer_ted. please read my first two posts in this topic. they represent the 'basics' in getting a new motherboard working. If you have followed the directions indicated in them precisely and thoroughly, and still have problems, then please start a new topic indicating what motherboard you are using, and we can try to assist you.
In the meantime, please be aware that simply assessing a power supply unit by its wattage level isn't enough. A decent quality model from a reputable manufacturer will always be better than even lower wattage units from a 'generic' supplier. Cheap power units are NEVER the best option!
To repeat the basic troubleshooting procedure for those having problems:
Power down and either switch off at the wall outlet or remove the power cord
Remove ALL plug-in components except the processor and its heatsink/fan, one RAM module (usually in Slot 1 unless the motherboard manual specifically states otherwise), and a display card if the motherboard does not have onboard video. If the motherboard has onboard video, remove an add-in display card also.
Physically reset CMOS either by using the appropriate jumper or by removing and later replacing the CMOS battery.
Ensure that the power supply is connected to the motherboard
Ensure that the front panel case connector leads are attached correctly to the motherboard.
Connect a keyboard and a monitor
Power up and see if the machine completes POST.
If the machine does not POST in basic configuration, check, double-check and recheck the front panel connectors, ensure that the processor is firmly and correctly seated in its socket, and if there is still no success have the basic components checked for functionality by a technician.
