I just went into BIOS 2 days ago when i noticed this Red Highlighted value in the Hardware Monitor section in Power menuEverything is running on stock i never touched the voltages or anything. Take a look in the Pic the 12v seems very low.... What could be the problem? is the Power Supply, Motherboard or the Processor? i even took out the GPU to check but it does'nt seem to effect with or without it HELP!
Try to reset your BIOS, some voltage settings may be incorrectly set
Sensor gone bad most likely. If the 12V reading really was that low the computer wouldn't even turn on.
If it is the sensor resetting the bios likely won't do anything. Flashing or re-flashing if you don't have it already with the latest bios,
ASUSTeK Computer Inc. - Motherboards- ASUS P5G41T-M LX
might reset it.
Ok i tried resetting to default settings nothing happened. I even updated the BIOS just before and still nothing happened.. What to do now? on CPUID Hardware Monitor i get these reading just like before updating the bios.
Softwares read the same sensors as you bios, so they have to show the same.
Short of contacting Asus about a possible RMA, not much.What to do now?
The fact that the computer even turns on with it reading that low sort of proves it is the sensor gone bad (did it ever show properly?), as like I said earlier the computer would not even turn on at all if it really was that low.
Software is also the most unreliable way to read voltages. Don't forget that the bios is nothing more than software as well. If you really want to know what the voltages are you have to measure them manually,
Test your power supply with a multi meter - Tech Support Forum
Yes it seems the sensor has gone badi do have Multi-Meter and this other tool the check the amps and other things from my dad's equipments but i dont know how to use them
If you have a multimeter you can test like this:
Multimeter: plug the black wire into the COM plug, plug the red wire into the V-Ohm plug. Turn the multimeter on and switch the dial to V (Volts) at the DC 20 scale (modern meters show DC as the red zone).
Computer: Open the case and find an unused plug from the power supply that has yellow and black wires. Move the plug to an easy to reach location. Turn the computer on.
Now take the pointed lead on the red wire and make contact with the yellow wire connection in the plug, then take the black lead and make contact with the black wire connection. Read the volts on the multimeter display.
That sounds very complicated to me.. Can i test it while the PC is on? and should i plug the Red pointed pin with yellow wire and Black pointed pin with the black wire?
You need to!
Yes. By convention the yellow wires are 12v leads. The black wires are grounds. The multimeter, connected as described, will measure if you are getting a true 12v.and should i plug the Red pointed pin with yellow wire and Black pointed pin with the black wire?
If you are uncomfortable with this then don't do it. While it would be hard to mess anything up (you'd have to cross - or bridge - the connections to short anything out and do damage. (Don't do that!).
Can you get your father to show you how to use the equipment? It really is a good skill to know if you are going to play with electronics.
