Windows 7: Problem in BIOS HALP!

Problem in BIOS HALP!

I just went into BIOS 2 days ago when i noticed this Red Highlighted value in the Hardware Monitor section in Power menu Everything 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,

might reset it.

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.

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,

Yes it seems the sensor has gone bad i 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 also it was'nt like that before and the readings in CPUID HM and BIOS are both different which is weird. From few days my some of my Dual-Layer DVD-R's are'nt reading on both my Drives before they used to work fine without problems and they are scratch-less dvd's. Could it be related to any hardware problem?

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.

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.
