What kind of damage could be caused by...

post #1 of 10
Thread Starter 
I was wondering what possible risks are there for not hooking up the 4-pin connecter with the 20-pin connecter into a 24-pin motherboard. My friends computer stopped working and when i looked inside thats the onlything i could find wrong. Could this have fried the cpu or the motherboard? They had someone else build the pc for them and apperantly he didnt hook up the 4-pin part but plugged in the 20-pin part leaving 4 pin holesont he motherboard open. Could someone please help me out??

Nope, wouldn't damage it.

The PSU itself could be faulty and have stopped outputting the right level of voltages on the rails or one of the parts may simply have died

if anything, the system was undervolted but thats not to say it cant cause issues in theory. try ant test the output of the psu and check for anything grounding out. if that all looks ok connect the psu correctly and see if she'll start up

Not a problem.

In fact, a lot of HP/Compaq, Gateway/eMachine computers use 24-pin motherboards with 20-pin power supplies.

ok thanks everyone. ill try that and im still trying ot figure out any other causes for the computer not turning on. Everything is hooked up correctly and when i turn on the psu the lights on the motherboard where the ethernet cable plugs in is lit up. Could it be a bad psu?? It is one that came with the case i believe and looked cheap.

check the pc case power switch and its connections to the mobo, maybe one of them little wires came loose. In fact check all your connections and seating just to be sure.

Its possible the momentary action of the power switch isnt happening (bad switch) or isnt being received by the mobo (bad/broken connections)

if all that looks good then maybe psu took a dump. Have another to test with?

It could have sent a surge of power through the rest of the system and destroyed every component but that's unlikey, although it is possible.
