Hello again

I have a problem, or at least I think I have a problem. Just recently I went onto ASUS AI suite to check my fan speeds etc. Then I noticed that the +5V is suddenly onto 0.000. So then, I went to the BIOS to check it from there and it says N/A.
The BIOS firmware isn't up to date but I have a feeling I shouldn't use this unless it is highly recommended for this problem.

My motherboard: ASUS B85M-G
OS: Windows 8.1 Pro and Windows 10 Technical Preview

Why are you looking at the voltage for? Are you using a different video card, than the onboard GPU that came with your computer?

I actually didn't look specifically for the voltage but it was a coincidence. I'm a person who kinda gets ''scared'' quickly when something is wrong with one of the voltages when I shouldn't be at all. And yes, I am using a different card then the internal GPU of my CPU. Never used the onboard GPU from my CPU.

This is becoming more and more common and by "this", I mean more and more motherboards are going with +12V and not using +5 anymore (except +5Vsb standby). The Gigabyte board in this computer does not use or have a +5V sensor either. So I don't see any +5V reading with HWMonitor, Speccy or in my BIOS either. As long as your +12V and +3.3V are within ±5%, you are good to go.

If your computer needed +5V and it really was missing, you would know it.

Ah I see. I was just wondering if this might become a issue. But for the note, I have an ASUS B85M-G, not an Gigabyte model.

I saw that. I mentioned my Gigabyte to illustrate it was not just ASUS.

Ah alright. Well in this case, I hope this is a sensor problem and not an actual problem. But as you say, if motherboards don't need 5V anymore, then it shouldn't be a problem at all.

Now if this is a sensor problem, is there any way I can solve this or should I just leave it and ignore it?

I don't believe it to be a sensor "problem". More like there is no sensor because it is not needed.

But if there were a sensor that had failed, there's nothing you can do about it because it is imbedded somewhere in another IC.

But you can jam a multi-meter probe into the heart of your computer to measure the +5V, or better yet, get a PSU Tester like this one that has an actual LCD voltage readout.

Ah, well I did saw though not long ago the +5V on my motherboard and on ASUS AI Suite. But yeah, if I really want to be sure about this, I better get that PSU tester.

Not sure then why you would no longer unless the sensor did go bad, or there was driver update or BIOS update that changed.

I haven't installed any driver update nor a BIOS update. Though I have dualbooted just recently the Technical Preview of Windows 10, but I doubt very much that that could've done something.

Well, again, if it were needed but missing, your computer would not be working so you might want to pick up one of those testers because they are nice to have handy. Just make sure it displays the actual voltage. The cheaper ones just have a LED that indicates voltage is present but not necessarily within the required tolerance range.
