iMac flickers when turned on

When I played something on my iMac last night I was thirsty so I went to go get something to drink and when I came back the screen was black. I thought the iMac just went to sleep so I tried to wake him up but it didn't work so I restarted the iMac and instead of a screen white when you turn it on the screen was flickering colorful then I went on the Internet with another device and looked for my problem but I couldn't find it. When I got up this morning trying to start again, he began to blink with 1 million colors like last night so I searched the internet again once for the problem and I couldn't find some I decided to ask the support of apple.

Looks like you need to make an appointment and take your iMac at home, I don't think that there is a quick solution to your problem. You can try to see if your iMac will start in Safe Mode, try safe mode if your Mac does not commissioning - Apple Support

    iMac won't turn. Startup disk is full. TDM won't let me edit.

    My iMac turns off 10 seconds after the start to the top. I tried repair disk running, to no avail. What is happening is because my boot drive is full, off the 500 GB I partitioned in mac, 493,63 GB is taken up. I bought a thunderbolt cable to access the TOC on my mac book, and I have access to my files now. The problem is that I can only copy files. Authorities say I read and write permissions. When I start my host computer, it says "you can still open or copy the files on the disk, but you cannot save changes to the files on the disc. Back up the disk and reformat it as soon as you can. "I'm trying to copy all my files on this computer and remove what I don't want copies, then reinstall OSX on my iMac. The problem is that some files are native to all OSX, so it would prevent me from copying the files. For example, if I want to copy my applications folder, it stops to copy once it reached the app store, because it cannot copy that. It is a problem because when it comes to the library, there are small files in there that I don't know if I can copy, then it stops at the copy and I end up with half of my files and I don't know what I need and what I have.

    Everything you need to copy the disk, then start the iMac in recovery (command-R) mode. Wipe the drive and reinstall OS X from the recovery console.

  • When I play FreeCell it flickers and sometimes it flickers when I click and I select what's behind it on the desktop

    Original title: Twinkle

    I searched this but can't find anything that really seems to apply.

    When I play FreeCell it flickers and sometimes it flickers when I click and I select what's behind it on the desktop.  I noticed recently that other things sparkle too but have not been able to narrow down the what and where.
    An article I read recommended from is safe mode and see if the problem persists.  But you can't run FreeCell in safe mode.  I don't know any other way to test.
    Yes, I know FreeCell is lame, but that's what I need with my coffee in the morning.

    If the game does not work in 'safe' mode, it turns on a "clean boot"? Don't forget to reset to normal boot once you have studied. If the game works and there is no flickering then don't follow the section "how to determine what is causing the problem by performing a clean boot."

    Have you tried updating your graphics card drivers? Take a look at the support site of the manufacturer for your PC and see if there is any updated versions of the GPU for your PC drivers. If there are new compatible drivers available, make a restore point and install it, then try them. If there is more trouble, you can always "roll back" to the existing version.

    You can also try a SFC/scannow scan to see if that detects and corrects any problems.

  • Just changed Safari on my imac. When you use find menu safari gave me the opportunity to "find in this page" which was an incredible aid during a search. Is it possible to have this feature using firefox?

    Just changed Safari on my imac. When you use the search menu in safari, I had the opportunity to "find in this page" which has been an incredible help while doing research and looking for specific words/phrases. Is it possible to have this feature using firefox?

    I think that Safari has the same keyboard shortcut in Firefox 'cmd + F' on a Mac or a 'Ctrl + F' on Windows.

    Look in the lower left corner to find. There are more likely to be next and previous differences in keyboard shortcuts, but continuing in the search bar at the bottom no matter what browser you use. It is an 'X' to reject the search bar. In Windows, the "Esc" key will reject the bar if you are in the search text entry box.

    I have a late 2009 iMac. When I tried to upgrade to El Capitan. He said that the CHIP shows the h/d is a failure and can not be updated. I have install an external withEl of h/d Cap but it is very slow. the h/d is USB 3 but the iMac's USB 2. the h/d is only 5400 RPM. a 7200 RPM 7 / would accelerate the iMac?

    No, because the limiting factor is the computer is USB 2.0, which is how it connects any external drive apart the external drive. As USB 2.0 is much slower, there is no real advantage to a 7200 RPM drive. What you need is a Firewire enclosure that supports FW800 which is much faster than USB 2.0.

    I thought that the LCD screen was broken, but it turned itself off recently on a couple of opportunity (I guess overheating) I think maybe that's the problem.

    If its possible to have it repaired I would like to know a little more before you cast.

    What you mean with I would like a little more knowledge? If the LCD is damaged it must be replaced. If the warranty is still valid, contact service in your country as soon as possible.

  • When turned on the computer it says - Error loading C:\WINDOWS\aluzonah.dll - the specific module could not be found

    When turned on the computer it says - Error loading C:\WINDOWS\aluzonah.dll - specific module is not found - the computer seems to work very well however.

    When turned on the computer it says - Error loading C:\WINDOWS\aluzonah.dll - specific module is not found - the computer seems to work very well however.

    A Google search for this returned no success other than your own message.  This suggests that the file refers to malicious software.

    You have a recent version of an antivirus with a current subscription application?  Have never leave you the subscription expires?

    Startup like these messages can occur if your antimalware application has deleted the payload real malware but has failed to clean up the start of the call.

    First download, install, update and run the following applications of malware free 2 the possibility that one or the other will detect and remove these remains (as well as anything else that your original scan could not detect):

    Malwarebytes

    SUPERAntiSpyware

    If these two applications running is not the message disappears, you will need to know where the call to the missing dll file is now done.  The best tool for this is AutoRuns:http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx the main problem with the help of AutoRuns is that he finds the startup items as much as it can be a little overwhelming. One of the good features of AutoRuns is that you can prevent an element of commissioning by unchecking the box, but if you decide that you really want to start, just re-check the box.  Once you are sure that you will never need of the item to start, remove it.

    Typical advice is to check the logon tab, but because the now-absent file is a dll, it is not likely to appear online in the logon tab.  Yet, take a look at the connection tab and if aluzonah.dll is there, or if there is a line of starting an application of suspect search, a Google search suggests is malware, uncheck the box and restart.  If the entry is far, re - run AutoRuns and remove the line.

    The next place to look is the Winlogon tab, which should have little, or no, entries.

    If you have not yet found the wrong entry, click the all tab, click the top row and then click on file > find and search for aluzonah.dll.  If you find an instance, uncheck the box and then manually move the selection on the following bottom line then press F3 to "search again".

  • BlackBerry Smartphones BB Bold only charges when turned off

    Hi all

    I have a BB "BOLD" for a few weeks now.  When I plug it into the charger, it does not seem to load when the device is on.  The loading symbol appears in the upper left corner, but if I unplug the device after a period of time, the battery status symbol doesn't seem like the unit is charged.  In addition, the light yellow of load not flach when plugged in when turned on.

    When I switch off the unit and plug it in, I get the charging flashing yellow light and accusations of pretty good device.

    I also tried it with the device is plugged into the USB port on my laptop (I have DeskTop Manager 4.7), and it does not seem to load there either, although I have not tried to load from the PC the unit is turned off.

    It is a real problem, as very often, I want to load the device then turned, while I do miss phone calls and emails.

    Thank you.

    Adam

    The battery on the top icon left not enough resolution to be used for something other than a general indication of charge level.

    Go to Options, State to see the level of charge of the battery percentage.

    When I have my camera on during loading, I do not see the battery flashing yellow light. In fact, I didn't "BOLD" had one of these!

    In any case, see if the percentage level changes during loading with the appliance on.
