palpitation in lower toolbar of pixel

A line "pulsed" colored pixels suddenly appeared in all of the screen in the lower task bar.

Jolly_Rogers thank you for such a concise and clear diagnosis.

The geeks at a store in particular tried to tell me that it was probably "a virus."

It must be a hardware problem because it persists in the Bios.

I'm even more certain that he is material, because I had already checked in update the graphics driver and Bios Update.

Can't wait to see this happen on my beloved DV4 after only three years, but such is life.

Thanks again.

  • I get a widow in my lower toolbar that rpet low disk space, and when I click it to try to delete the old files, it does nothing... so what do I do... ?

    I get a window in my toolbar lower repeating me low disk space and when I click it to try to remove the old files, it does nothing... so what should I do to get rid of the files in a "D" file...?

    Please perform these steps and the back of the report.

    Click Start, click computer, and it will display your hard drives and their letters. Normally C: is your operating system and where everything is stored (user: files, programs, Documents, photos, etc.). The D: is your RECOVERY partition and contains a copy of the first installation of the plant. The D: is small, about 9 to 15 GB, depending on the version of Windows.

    For example, my C: displays 306 GB free (unused) 374 GB (hard disk capacity). D: shows 2.11 free 11.5 GB GB. This is normal for HP, Compaq and others. New HP (Win 7) include an E: with less than 1 GB of capacity, to store a program utility tools. These so-called hard disks are in fact partitions installed on a physical hard disk, but not to concern. The c: partition free space is your important answer. BeAware that the D: and E: (if you have the configuration described above, are never to be used as restore points, or your personal files, they are allocated by the manufacturer to support the reinstallation of the operating system.) My example shows that my C: partition made only 68GB used on the disc, 306 GB is free (unused) 374 GB capacity.

    (1) report with numbers, and you can be helped.

    (2) Vista writes copies ghosts of all your documents (previous versions of the files). These can take many GB.

    (3) when he gets less than 20 percent free, you start to have problems with the disk defragmentation. Less than 10% results in critical problems, the problems of performance and for the worse.

    (4) if the number of free GB is really a low disk space issue, you need to move some of the large data files (pictures, videos,...) out on CD or DVD.

    If it helps, let me know. I'm not a moderator, just a user trying to use simple language to help others.

  • How can I increase the resolution of an image low resolution without pixel mixture?

    So I have a 64 x 64 image, and I want to increase the resolution to something like 256 x 256, with the same pixel "ratio" (yes I know ratio isn't the right word) which means they're still visible square, in this case the pixels turn 1 x 1 to 4 x 4 same color without mixing pixels next to them. I want to do this to allow better re-sizing of capacity but still be able to do in a project of low resolution to facilitate the design. How can I go about it?

    I made this screenshot while Trevor responded. The underlying file has been resampled from 25 to 100 pixels, and as you can see the edges are well preserved.

  • Some how a low toolbar loaded it is autonomous and have several issues

    Charge of 'mapsgalaxy' and a 'request' toolbar presented themselves. Hate to ask as it is for me a good search engine. It has changed my home page to ask, with on demand, took me 45 minutes to correct this. Topical issues has can't circumnavigate the crazy ask toolbar that I don't want. Second, when I click on the + symbol to open a new tab that was sent ahead with a blank page, well today, it opens a page with search ask thing in the middle. Can't find 'request' in one of the programs to remove so think he is hiding somewhere else. Found it in the (not sure what where are the options or preferences) and disabled it. Don't know how I found out who or how to get back to work on other issues and stumbled upon it. Maybe extensions? Please help thanks.

    Note that Windows hides certain default file extensions.
    Among them .html and .txt, so you can see the file name user without .ini and .js file extension.
    You can see the type of actual file (file extension) in the properties of the file via the context menu in Windows Explorer.

    Yes, you can remove the user.js file or perhaps rename the file or move it to a different location.

    Do you have inspect you the contents of the file and use 'open with' from the context menu to inspect the file in Notepad?

    Do not double-click the file and which make Windows tries to run the file as a JScript file and which will fail.

  • Download now only show in a window, not on the bottom? How to get back too low-toolbar downloads, please? Thank you.

  • don't get rid of the classic theme - I HATE TABS squared & I miss the toolbar at the bottom that tells me where I'm trying to go to a new page.

    1. How can I get rid of the classic theme?-hating to the square of the tabs.
    2. where is low toolbar that lets me know (such as to empty the trash on my Mac) where I am trying to go to a new page?

    Make sure that you run not Firefox mode full screen (press F11 or Fn + F11 to toggle; Mac: Command + SHIFT + F).

    Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem.

    • Put yourself in the DEFAULT theme: Firefox/tools > Modules > appearance
    • Do NOT click on the reset button on the startup window Mode safe

  • Photoshop UI loading low resolution on retina MBP

    Hi all

    For the past few weeks (I don't remember exactly when it started, so I can't tell if an update has caused), the user interface of Photoshop CC 2015 has been low dpi on my 2015 13 "MacBook Pro of retina. This is the interface: frame text interface user and icons, buttons close/minimize/maximize on the application, start to load, all modal dialog boxes, etc. All loading low DPI, visibly pixelated on the screen high resolution.

    There has been some updates since I first noticed the issue (and I'm perfectly up-to-date now), but none of them were fixed.

    I tried to restart my Mac, dumping my preferences, uninstall extensions, disabling the GPU acceleration, toggling the display in the preferences system resolution (the problem persists on all modes of scaling, including mode 'more space', which maps the pixels of the interface device pixel 1:1) and finally, completely uninstall and reinstall the app CC Photoshop. None of my other CC apps share the question.

    I have an Apple Thunderbolt external Display that I use sometimes. The problem persists with and without the connected display (and through the above troubleshooting steps with and without display).

    I did troubleshooting above with the people of @AdobeCare on Twitter, and they asked that I post my case here.

    Any thoughts on how to solve this problem?

    Thank you

  • PSE7, how can I change the image pixel size?

    Hello

    PSE7 I am trying to resize photos at a lower resolution (100 pixels x 750 pixels) for a slide show of Premiere Elements.  In the editor, when I choose Image->-> resize, I only have the ability to change the size of the Document.  Can someone tell me how to access the dialog box that allows me to change the width and height in pixels?

    Thank you

    Patti

    First of all, you need to activate resampling before the dimensions of the window pixel box becomes active.
