CPU Over Voltage Error and Power Supply Surges Detected

June 19, 2015 at 16:42:20
Specs: Windows 8.1
Hi everyone I was wondering if you would be able to assist me with this error that I can not solve. As the title states I get an error on boot that says CPU Over Voltage Error and Power Supply Surges Detected. In the BIOS it the CPU Voltages are in the red. Their values are in the image below.

I tried taking out the CMOS battery and putting that back in, along with a few other work arounds but with no luck. Hopefully you can assist me in solving this problem. Thanks ahead of time for your assistance.

Here are the computer specs, it was recently built probably about 6 months ago.

CPU: Intel Core i5-4440 Haswell Quad-Core 3.1GHz (3.3GHz Turbo)
Motherboard: ASUS B85-PLUS LGA 1150 Intel B85 SATA 6Gb/s USB 3.0 ATX Intel Motherboard with UEFI BIOS
GPU: A GeForce GTX 750 1GB 128-Bit GDDR5 PCI Express 3.0 FTW w/ ACX Cooler Video Card
RAM: HyperX Fury Black Series 8GB 240-Pin DDR3
HDD: Western Digital Blue WD10EZEX 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive Bare Drive
OS: Windows 8.1 64bit
PSU: Rosewill RD600 – Stallion Series 600-Watt Power Supply – ATX 12V V2.3, SLI & CrossFire-Ready

It is difficult to imagine this is down to anything else except the PSU itself, unless the sensors are faulty.

Always pop back and let us know the outcome - thanks

Thanks for your response Derek. Should I switch the PSU out for a similar one and see if it will boot?

Alright. I'll do that right now and let you know the result. Thanks again. Hopefully its as simple as a faulty PSU.

I swapped out the power supply and it did the same exact thing. What else can I try?

Does it boot up and run normally?

However lightly loaded the PSU is it is hard to see why you should get high voltages. Only thing I can think of is the sensors are misreading or maybe some common associated component or connection has failed.

You could try this on it and see what voltages it shows:

It might tell us something but even that relies on the sensors and their wiring.

Always pop back and let us know the outcome - thanks

When I attempt to boot it up from the BIOS it shows the windows 8 loading screen then turns to a black screen and I can move my mouse around. Nothing I input to the keyboard does anything. As for connections I unplugged everything and plugged it back in. There's no way for me to check the voltages using that since it won't even boot properly.

Tricky but sounds more serious than just sensor trouble. I'm now more inclined to think that you have CPU issues.

Keep watching for other ideas on this one but in the meantime see this general input on here for a similar issue:

Well that's no good. Hopefully someone else can input here as well. Thanks for your help thus far Derek. I'll read through that thread to see what I can find out.

Couple more thoughts:

As per the link try resetting CMOS.

When you fitted the CPU did you apply the thermal grease using the exact method specified for your CPU? It is very important because the recommendations vary. If you do reseat it check the pins at the same time.

I've assumed you are not overclocking.

Always pop back and let us know the outcome - thanks

Trying to reset the CMOS as we speak. I believe the thermal grease was applied correctly. I'll see if I can reseat it and I'll check the pins.

Correct not over clocking.

On another thread I created on a different website someone has suggested that the Bios battery could be dead. Do you believe that this could cause the issue?

If you remove the CPU you will need to remove and replace the thermal compound. Here is the proper way if you look up your CPU:
http://www.arcticsilver.com/intel_a...

I doubt that it is the CPU battery. Using the CMOS jumper (or removing the CMOS battery and then tapping the power on button 2 or 3 times) will clear the CMOS memory. Then immediately boot into BIOS set up, Reset to Defaults, Save and Exit and boot back to the BIOS and make sure that time, date, CPU, RAM, Graphics settings, etc. are properly set up for your hardware. Set as needed, save and exit.

It did sound like the power supply at first but once you tried a second power supply, it must be something else. If the BIOS settings do not do it then it is either 1- The improper installation of CPU - possibly thermal compound on CPU socket/bottom of CPU; 2- Bad CPU; Bad motherboard. 3- Small possibility of incorrect plugging of power supply into motherboard (PCIe 6pin/8pin plugs look a lot like CPU 4pin/8pin connectors, etc.) 4- Smaller possibility of incorrect voltage at outlet (though the power supply should be able to handle a fairly wide range of voltages without allowing incorrect voltages going out).

"it was recently built probably about 6 months ago. " so we can assume that it was working properly for a while?
If there was anything unusual going on with the machine or even with other electronics in the house, or even with a problem with something apparently unrelated like a transformer fire on an electrical pole nearby, please let us know this as well.

You have to be a little bit crazy to keep you from going insane.

There's no way the PSU can put twice the voltages per rail or that your CPU temp is -63C.

You likely have a reporting problem. Try updating the BIOS. The latest version is 2304 & was released just a few weeks ago. Any idea which version you currently have?

Riider the BIOS is up to date. That was one of the few things I tried before posting.

Fingers I'll be going through your steps right now to see where I can get.

"so we can assume that it was working properly for a while?" Yes handled everything without any problems. It worked the day before posting this, but when I took it and hooked it up for a LAN the problem occurred. No other electronics have any troubles. The other machines that were hooked up to the same surge are perfectly fine as well.

I encountered similar problems with b85-plus. vccin, 3v 5v 12v all show extremely high voltage (twice normal, exactly same value as in Thedap24's img). Tried a new psu, load default bios, to no avill.
If you have any solution, would you kindly post it here?

You would be far better off raising a new post of your own rather than inputting on a thread which has had no responses since June 20. These are the reasons:

1. A new post would be put at the top of the pile and therefore be seen by more helpers. Few people will come back now to this old one.

2. No two problems are really alike. We need to look at "your" problem and "your" spec.

3. If anyone does try to help with your situation it can get confusing with two posters on the go.

4. One original poster per thread is normal forum practice throughout the internet.

Thanks for your advice.

Considering my highly similar problem as thedap24, just thought I could get to the solution from him directly.

oh, well. I'll go start a new post then.
