Computer screen problems

Recommended Posts

My computer seems to be having problem with the letters on screen, sometimes the letters will be broken up in random places and sometime letters will disappear completely. Facebook and youtube is especially bad for it but even happens here on sfn occasionally. Anyone else have this problem or have any ideas about what might causing it?

Maybe something with UTF-8?

Do you always have the https padlock in the address? This is at first sight the most important.

But the problem probably comes from the web browser. But it may be something else. Once I had a pc that had caught the humidity, and was having at the start the problem of writing characters on the screen...

You might have hit the nail on the head, I have an aquarium beside the tower... But no, HTTPS is not in the address...

But you can see the http? If it's without the s, do not connect with a login and password, because it means that your connection is not secure. In this case you must reset your OS (windows or mac) But you should at least see the padlock on the web browser.

It is unlikely the problem is because of HTTPS.

Facebook and youtube is especially bad for it 

Facebook and youtube have lots of content so it is harder for your computer to load them which suggests a CPU or GPU problem possibly causing a short circuit somewhere.  A short circuit could possibly be caused by moisture but could also be a manufacturer fault. I would recommend the following:

  1. Check to see if you got a driver update recently and if so then downgrade the driver to the ones provided by your manufacturer. 
  2. Open your computer and check that there is no corrosion/dust/moisture in your machine. (Note if you have a warranty on your machine you may prefer to just return it to the manufacturer)
  3. Reinstall your operating system to ensure you don't have any malware.

If the computer is very old it may be worth replacing it at this point but if it was bought recently you can.

  1. Return the computer to the manufacturer for repair.
  2. Take it to a competent professional who does PCB repair. Note the vast majority of computer repair shops don't have the equipment for PCB repair.

Make screen-shot and attach..

Problem with display CRT, LCD or LED, is completely different problem than e.g. UTF-8/Unicode issues during translation, or entire network transmission being passed through hacker's proxy server without HTTPS anywhere..

Where you would expect https it just has a image of a closed pad lock. It usually happens when I pass the cursor over the script, sometimes it goes away but sometimes it doesn't until I switch pages.

If you have strange letters, it must necessarily come from the ASCII code via Unicode https://en.wikipedia.org/wiki/ASCII#Unicode
But he has the padlock, so his SSL is not affected. The problem comes from the chipset rather than a software problem in my opinion.

For these connections like ISP, the proxy only uses a bridge of an SSL tunnel and does not duplicate the certificate. Otherwise it becomes a Man in the middle problem https://en.wikipedia.org/wiki/Man-in-the-middle_attack.

To check.
