I get a lot of 'noise' on my graph labview even when no sensors are connected. Any suggestions as to what this might be?
I'm trying to set up a test bed to measure the linear moving of a hydraulic cylinder and it trace over time to a graph in labview. I was getting erroneous readings on the grapn (a point of tension for every ten samples). I have disconnected the wiring of the Terminal Board of my data acquisition card and the chart fills with 'noise '. If I remove the plate Terminal and move the wire that goes to the data acquisition card, the graph becomes fixed.
Any suggestions as to what can be causing this? All of the components are new, but would it be a bad block, the driver or data acquisition card?
Thank you

My speakers are white noise from time to time even when no audio plays
I have a gateway all-in-one and for some strange reason, I get some white noise on the occasion of the left speaker. -What or is it a fan there that makes noise.
Another possibility is static for several other power cords?
Also, most based GSM cell phones can cause this is the phone is close to the speaker (s).

The secure connection failed
An error occurred during a connection to mail.yahoo.com. The peer certificate has an invalid signature. (Error code: sec_error_bad_signature)
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem.
The most common reason for the 'sec_error_bad_signature' many sites seems to be the shield of Web of Avast. Web Shield intercepts your navigation and filter, but to filter sites secure, it has "fake" certificates for Firefox. Avast have set Firefox to rely on its false certificates, but which seems to fail on a regular basis.
To test this theory, try disabling scanning of encrypted sites. I saw these steps in another post:
- Open the Avast dashboard on an affected system.
- Select settings in the left side menu.
- Adopt a Protection Active.
- Click on customize next to the Web Shield.
- Uncheck the option "Enable HTTPS analysis", and then click ok
If that solves the problem, but you want to filter encrypted communication, you need to import the Avast! signature in Firefox Certificate Manager of certificates, References tab.

I use Firefox 18.0.
I searched the internet for a solution to my problem, and the closest result is the anchor point called Mozilla "Firefox (14.0.1) was last updated added to the so-called"easy inline"which is very, very annoying. Please, how can someone, I TURN IT OFF? ", July 18, 2012.
I followed all the recommendations but phrases "randomly" always become hyperlinks that display ads 'balloon' on the passage of the mouse. As Yontoo, I remember downloading some software over the summer that brought Yontoo with her, but I uninstalled since both. When I came across the support article, above, I followed the link to uninstall Yantoo and he did it again.
Currently, "Yontoo", nor "Easy Inline" appear as Firefox or modules extensions, and there is no folders or files by (or container) these names anywhere on my hard drive.
Does anyone have a suggestion as to what this might be and how have it off, once and for all?
Thank you

I can't get my pictures to download to my iPhone 6 s on my MacBook Air, even when they are connected by cable.
What happens when you try? Import window is empty in Photos for Mac, or if your iPhone is not recognized?
If import window is empty or does not display do not all the pictures, you probably have iCloud activated on your iPhone photo library. Then you can't import photos from your iPhone, because they are stored in iCloud and only mirrored on your device. In this case to upload photos to your Mac using iCloud. You can download the photos from iCloud by using the Web page at www.icloud.com and the Photos.app it.

Re: My laptop makes a lot of noise
Hi, my name is Akram, I come from the United States of America.
I got this Toshiba laptop last year, I have all the details it s bought in the UK and sold in Saudi Arabia.
Recently, since a month since my laptop makes a lot of noise can be the fan or the transformer.
I'm a medical student, I t really know.The noise is so boring that I put t carry the laptop to the library or College. Everyone in my class knows once I have started using my laptop if I take it, irritated by all the comments made by my friends. I took the laptop for repair, somehow, I browsed your site and received your Toshiba repair depot.
As I was in warranty until last week, I went to computer services of DATA VISION, 39th street, New York City, but to add to my problem the people he said he just cleaned up and said what he of done. But the problem is the same.
I had to go again, then he said that all laptops Toshiba make these noises. Isn't annoying to know this?
If it true s all Toshiba laptops make these noises, I beg you literally.Please, make not of the more portable, it s really annoying to know and just Fellows try to convince me.
Nothing is managed best by Toshiba. I'm if unfortunate and disturbing why buy it.There is no management what so ever.
Thanks I hope someone will never correct the problem, you can contact me on my mail id '[email protected] or [email protected] '.Hi mate
Welcome to our community of small notebook
Firstly if you are talking about a Toshiba laptop then you should post some details about your laptop. Who needs to know which model you have?
Second, I don't know what sound you hear you noise which is create by module cooling fans?
Just a comment in this regard:
> As I was in warranty until last week, I went to computer services of DATA VISION, 39th street, new york city, but to add to my problem people there said he just cleaned and said its done. But the problem is the same. I had to go again, then he said that all laptops Toshiba make these noises.I put t know if it s your first computer laptop or not, but if you're talking about the noise created by the cooling fan, then you must know that you would hear on all laptops cooling fans!
If the heat dissipation is higher, then the cooling modules must run faster and so the noise could be stronger. But you can also reduce noise if you define the CPU and modules cooling to a lower return. This may be down to the energy economy of Toshiba.I have had three different notebooks from Toshiba in the past. Now I have Satellite U400 and I'm happy. Of course, I can hear the fans running but that's nothing unusual.

Tecra S3 produces a lot of noise!
Hello
I used a couple of Toshiba in recent years, but felt that the new Tecra S3 produces a lot to a lot of noise. This noise is generated by the fan. Even when running in the mode of dynamic switching, fan is on continuously, even after running idle for some time. The CPU temperature is 47.
Is this normal for a laptop produced this noise a lot?FYI: The machine has already because the graphics card was vice, heat generation that makes more noise.
Eddy Kleinjan
Hello
I put t think that it s a failure or malfunction of the equipment.
It s a simple fact that the cooling module must run due to overheating problems.
If the temperature rises to the fans works faster and louder
However, you can try to change some settings in the power management. Please check this possibilityGood bye

Satellite C750-A103 made a lot of noise - problem with the cooling system
My toshiba machine made a lot of noise... like a plane. And it gives me the message "a problem with your cooling system has been the detection.
Turn off immediately and come back for the service "."
What should I do? It has been recently formatted, also?+ The message was edited: mode number + added
You did not provide details on your laptop model and system that is installed on the laptop.
Even his I don't know how old is the laptop, but according to this short message, it looks like there is a problem with the cooling system.
Probably notebooks cooling fan doesn t work properly and the unit cannot be cooled as it should this can lead to cell damage through an internal temperature longer.

Hi I have an equium A60 and the fan seems to make a lot of noise, other notebooks I've seen seem to be very calm while mine has a strong constant drone to it. I found some places that it could be dust or dirt in the fan or heater. Can I ask that is the problem? and if so how would sort it?
Thank you, taf
Hello
On this way, no one can give you 100% precise answer, and we can only speculate. I'm don't know how old your unit but is perhaps time to clean.
On this path, vents are clean and the device can catch its breath. If you use the appliance for some complicated process and CPU should work under pressure, it is normal that the unit must be cooled a lot faster to avoid damaging the material.
Another thing: If you use the notebook as a desktop replacement you can put on something to make it a bit higher (maybe 2 or 3 cm). On this way the unit will be better cooled. Test it.
