yup but my dad is not alive and i'll have to do it on my own Thanks for the guide TVeblen and i will try this in the morning coz i can't seem to find it right now i'll be careful while im doing it so i dont mess up anything
Thanks Britton30 for the Molex Pic with detail and Thanks stormy13 for the very useful link as well
Ok i just checked with the Multimeter by setting the meter on DC V at 12v and checked with 2 molex connectors by plugging the Red Meter Lead to Yellow Wire and Black Meter Lead to Black Wire on the Molex and the meter goes to full 12v i checked twice and thrice times by taking out the black lead and insert back in. Goes to 12v on the meter :) so it means the PSU is working fine but Motherboard sensor has gone bad? should i send the motherboard in Warranty?
Yes. That shows you that the power supply is putting out an actual 12v and is good.
While you've got the equipment out you could also check the 5v lines (red) just to know.
That is up to you. Can you be without the PC for that amount of time and is it worth the problem?should i send the motherboard in Warranty?
Personally I would. My feeling is that if the sensors are bad there may be a more global problem with the board - or it is just a lemon - and I would want a new one.
Good job. Keep that multimeter handy!

How to check the 5v? You mean the red wire on the Molex where i tested with the yellow wire? :)
Yes im personally not feeling to keep the board anymore like that & not satisfied im also having problem with Dual-Layer disc reading + today i tried to overclock the processor a bit (im not sure if i was doing right coz i never done this before) first i went into the bios and set to manual and increased the fsb from 266 to 333 and rest was auto and saved settings and as soon as the pc restarted it was hanged so i pressed the reset button and the board gave me error Overclocking Failed and incorrect voltages etc so load setup defaults and working again. Maybe i did some mistake in OCing but still i think i would send it in warranty and get it replaced :) thanks for helping TVeblen.
Yes, you test all the voltages the same way. The red wires are 5v and the orange wires are 3.3v (If you can find any open spare orange wires to test, these will not be on a molex connector.).
As for overclocking - something I do not bother myself with too much - you should check out the SevenForums overclocking Forum and ask there for a step by step instruction. I'm sure you will get good help with that there, as there are many people who are really pushing their rigs.
Ok i just checked the 5v too and the meter stays between 4 and 6 right in the middle :) which means the 5v is also working fine on the PSU. I looked for orange or other color cable but i cant find other than Red, Black and Yellow cable colors
You can also test the voltages by means of a technique known as back-probing. With this, you test the voltages from the back of the main ATX power connector whilst it is plugged into your motherboard (and whilst it is powered on, obviously). You must use a digital multimeter for this.
With your meter switched to the DC Volts range (20V, if not equipped with Auto-ranging), insert the black probe into the rear of the connector so that it makes contact with one of the black leads.
With the red lead, employ the same method, but the colour of the lead will depend on the voltage you are checking.
+3.3V Orange
+5.0V Red
+12.0V Yellow
All voltages should, ideally, be within ±5% of the nominal values.
