Asus PL5P-LE the unit wont power up the green LED on the PS is
Asus P5LP-LE ,the unit wont power up the green LED on the PS is dim unplugging the 24 pin molex on the motherboard and it is bright like normally,as soon as I plug the 24 pin back into the mother board the LED go really dim again,is there a fix for this?

If you are having trouble with the power dropping off on the motherboard then this is a sign that you have a capacitor(s) and/or the voltage regulator has gone out on the motherboard. The issue may also be with the powersupply. I would try another one to see if this fixes the problem.
If you have the same problem with the other powersupply unfortunately there is really nothing you can do to fix this. However if you know someone in your area that does board level repairs then you can try to have the system fixed but this may not fully fix the motherboard.
The other thing to keep in mind is if the motherboard is not working properly then this could damage the other components in your computer. So you could end up frying the whole computer.
So if the powersupply is not the problem I would recommend that you replace the motherboard.
Let me know if you have any more problems or questions

The worse case if you can not fine the exact motherboard then you would have to do a clean install of Windows. Which might not be a bad idea anyways because if you were having system trouble it may have corupted the style="display:none;">brymus4ever

(1) Would the faulty components be in the area of the 24 pin connector ?
It is really hard to tell and it all depends on the design of the system. Note the normal places there the capsitors go bad are need the big power point like the video card, CPU and powersupply connection but they could have failed anywhere. This is why alot of people do not do bourd service any more. If you know any one in your area that does board repairs they might beable to give you some pointers where to test.
(2) And are there some places I can take some voltage readings to see how out of spec it is ?
I am unfamiliar with the voltages that would be normal or where to check them.
Thats the other problem here with out the service manual if it even has the style="display:none;">Bryan

(3) Would comparing the voltage of the 24 pin conector unplugged vs plugged in be a good way to narrow it down ?
I could easily measure it then strip a little insulation and plug it back in and see how much the voltage drops under load,which would be without the machine on.>
Yes testing the powersupply plugged and unplugged from the motherboard will help you see if there is a difference on the power pull from the motherboard. Also it is important to test the rails for the powersupply because it the rails are not putting out the right voltage then this can cause problems as well.
(4) which to me suggests a shorted component shunting to much juice to ground somehow./does this( guess )sound right to you as well?
That could be a high possiblity as well. You might test ground to see if you see an abnormally high ground voltage. Note you may have a little voltage on the ground from normal operation.
Let me know if you have any more questions
