The SPACEBAR keystroke will not stop.

My iMac recently started having a problem where the system gets a touch SPACEBAR which will not stop. I think that is what is happening based on the spaces added to the text on the screen in different applications, and from the keyboard Viewer which shows the SPACEBAR constantly depressed.

This isn't a device keyboard problem. I tried several keyboards. I also tried to unplug all connected to the mac and rebooting. The problem persists. I stop after several reboots (which seems a coincidence). I have also reset the PRAM, which seemed to have fixed, but now he is back (after about 24 hours).

I don't know what else to try. I have not installed new hardware in the computer, since I bought it (upgrade of ram). It worked fine for 1.5 years.

Try resetting the SMC by iMac SMC and PRAM reset, it may take several resets to work.

  • 18 XPS does not start, the power light will not stop flashing

    I was upgrade this computer to Windows 10, I did install one instead, but the children had spyware which even then showing upwards. I did a refresh, there no I did an installation and finally got in windows. Some updates installed and restarted.

    The computer was bricked since. The only thing that happens is the LED which indicates the power above, the button will not stop flashing white light. Connected or not connected, after having held down the power button for 5, 10 and 30 seconds, the led stops flashing for a while and then again. I tried several points of sale.

    Hi marcus,

    1. What is the full error message that you receive?

    2. have you recently trying to install a program on the computer?

    Method 1

    It is possible that some third-party programs installed on the computer is causing the problem.

    I suggest that you perform a clean boot and check.

    To help resolve the error and other messages, you can start Windows XP by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

    See the link below to learn more about how to clean boot.

  • The cursor flashes constantly and will not stop.

    Separated from this thread.

    It does not work. I'm not using Chrome. I use Firefox. The cursor flashes constantly and will not stop. Now, as I type, everything works fine. But in the contrary case, the cursor flicker with the small guard wheel busy with her.

    I had this problem as well - but it has happened when I loaded to the top of Chrome; I tried a lot of different things, but could not solve the problem.

    Then, I saw the post from TonyBrownCloudCo, and I knew he was on the right track here.
    Go to the Google Chrome settings > advanced settings
    Disable Google Cloud Printing - it is a used questionable spooler built-in Chrome browser, it must come from the recent update, because I've never had a problem with it before.
    I hope this works for everyone.

  • I tried EvevryThing! The "CREATED WITH ADOBE ELEMENTS 9 TRAIL VERSION FIRST" will not stop Displaying, even after I put in the serial number and Regerstered. Also the product does not show under my profile?

    I tried EvevryThing! The "CREATED WITH ADOBE ELEMENTS 9 TRAIL VERSION FIRST" will not stop Displaying, even after I put in the serial number and Regerstered. Also the product does not show under my profile?

    How can I fix it? Nothing in help or on the Site.

    Once you have registered the product, you should not see the banner of 'Trial' on NEW projects. This isn't the case, right? You only see on the project that you created before you register the product, right?

    That said, to remove the banner, go to the folder of directory on your hard drive where your project PREL files are stored and delete the folder called Adobe Premiere elements preview files.
