Re: intel d845hv board problems
This is not a problem with the wires. This is a failure of the motherboard and/or powersupply.
Try the following:
Take any components that are not necessary to boot the computer. Try turning it on again
Try taking all parts (motherboard, power supply) out of the case and then put them back in (I know that sounds weird, but it has worked twice for me before).
If you get to this step, either the motherboard of power supply is shot. The easiest to try would be a power supply. Replace it if you have one laying around or borrow one out of another machine for troubleshooting purposes. This is assuming they are standard ATX power supplies.
Place your finger on the heatsink for the chipset. Feel around for any extremely hot chips. If you find this, your Bios is shot. If you cannot locate the bios chip, just feel all the chips. The Bios chip should be mildly warm but never HOT!

There are may motherboards, but most have writing on them as to what is suppose to plug where. For example, for the power switch, the lettering might be "Pwr" or "Power" or "Pwr sw". The pins are usually together and should fit the plug on the end of the wire.
If you open the CPU cabinet you will find the front panel connection pins at opposite right corner to the motherboard IO ports (where we connect all the power,monitor,keyboard,mouse chords) You can easily identify it as below these pins it will be named as P_Sw or P_Bt,Pw_led ,Hdd_led etc
