computer wont switch on, might be psu

so i got my dad ringing me up today from his shop, and his comp will not switch on, so he brought it home, and ive just had a little look inside. one of the problems i had with mine was the psu, so naturally that was the first thing i looked at.

now i read a while back about the wire trick, and i looked up about it on here, and i couldnt find wether i was ment to keep the wire in place or not, anyways i tryed it, and whenever i shorted the two connectors, the light on the back of the psu went off. i dont have a psu to test with, so i dont really want to fork out for a new psu if its not the root of the problem?

thank you for reading

 

I'm pretty sure the two wires should be shorted temporarily. I usually pulled out a paper-clip with some plyers, tapped it to turn it on, then that was it.

If you leave it on too long, it will be the same as holding the power button down, which turns the PSU off entirely.

I could be wrong though.

 

tested it and :

you re wrong oneseventeen

it is the motherboard that keeps those wires shorted as long as your pc is on,

as soon as i remove the short from the psu it switches off

 

soo u recon that it is the psu thats clonked out in my dads comp?

 

some people noticed their psu doesnt start untill it has some load ...

my cheapass CPU does not have a problem with that but it is worth a try :

plug some old drives you dont really use in and try again
if it does not start, i'd blame the PSU for now

 

well just tried a new psu, and it didnt work, connected it up to some ramdom motherboard to see if it worked, and the new psu would work on that, connected the old psu upto it, and it wouldnt..

soo then i connected both in turn to the computer im trying to fix, with the button that i used to start the other motherboard, to try and keep as many constants in the equation, and neither the new or the old psu would work in that..

so im guessin im right in thinking that the whole computer is just died on my dad, motherboard and psu?

im gettin confused with it all.. hope ya can help

Have you checked things like the switch orientation on the motherboard front panel jumpers? If the power switch is on the wrong set of jumpers it won't turn on, the right place for it will be in the manual. I'm pretty sure your PSU is ok.
