Just one ? have you done overnight cmos clear as shown here:http://www.dfi-stree...04&postcount=24
Tried that last night. Did nothing just as I suspected
I've come to the conclusion it's shorting out on somthing. Because if I dont have the 4pin P4 connector plugged into the motherboard it powers up & I get 4 red leds which stay on.
If I plug the P4 connector into the motherboard & try to power up I get the symptoms listed above. Power on for millisecond then it automatically powers itself off with a very faint "click" which I have now narrowed down to the power supply. I've tried 4 different power supplies & I hear the same "click" with each one (all power supplies have been tested 100% fine on different machine). Must be some internal overload protection in the power supply kicking in to ensure the psu doesnt fry or somthing.
Thx for your help
