  • Mac or Windows, which version?
  • There may be several reasons for this.
    • Preferences corrupt.
    • Obsolete graphics drivers.
  • Solution
    • Try resetting the PS tools. (See screenshot)
    • Try resetting the PS preferences - to restore preferences quickly by using a keyboard shortcut: press and hold Alt + Ctrl + Shift (Windows) or Option + command + shift (Mac OS) when you start Photoshop. You are prompted to delete the current settings.
  • • Update graphics card drivers
    • AMD - AMD Catalyst 15.10 Beta Driver for Windows
    • NVIDIA - drivers | GeForce
  • Also, try opening the PS, then go to preferences - performance and uncheck CPU chart use
  • Now, restart PS and then try to use tools again.

• The time on my Ipod will not change when its coastline, Wifi disconnects randomly, screen goes green and red and restart full iPod.

  OK so this problem started about two days ago. I noticed that my time was off so I went to settings > General > Date and time. I changed the hour correctly but when I locked it and got out of her for a few minutes, it was always the same when I changed it. For example: this morning, back at the exact time that was at 10:41 20 minutes later, I changed my time and it was still stuck at 10:41 time will work properly if I am constantly on my IPod and do not block. I really need to use the alarm when I wake up every morning! I've tried everything to fix it, but nothing seems to work. Reset my IPod do not even help.

  This issue has also started two days ago. I noticed that the wifi on my IPod touch 5th generation cut off while an application is open, but when I close it then connects back. It is only on my IPod, but not my IPad. It's pretty boring. I also tried to reset my router but it always disconnects.

  The latest happened just yesterday. Again, I've tried my time is correctly set when all of a sudden half top of my screen turns red and turns green half lower. The screen then goes to black and my entire iPod restarts.

  Thank you very much for the help. :-)

• iPhone 5 c randomly open and use apps

  Ive had my Iphone 5 c for a few years and never had any problems. But recently I've had a few problems with applications seemingly randomly are opened and used. Used by sense that things will be clicked or pressed. For example, once I looked at my phone to see that he changed their apps and missing out on my clock application, go to the timer and had set a random time and tune. Currently I wouldn't be a game and have him by my side just to come turn on my screen and see several things in the game be enabled (for example, power-ups etc.) what is strange, is that I saw never actually happen. Instead things listed above will be only seem to happen when my phone is in my pocket or on my side. Also I don't understand how he could unlock my phone, even though I have a password.

  Before that, I dropped my phone on an outdoor stone floor causing in the middle of the screen to feel strange and cheerful (hard to describe). I did not notice that other problems and even this problem with the screen do not seem to affect my phone somehow major.

  Is there a possibility that my phone might have been hacked?

  Or could it be something to do with my screen is broken?

  I just want to know the problem so you can fix and ease my mind.

  Currently on IOS 9.1

  Any help or advice would be appreciated.

  Hello!

  It sounds like you are dealing with a ghost screen.

  Given that the phone had some physical damage, this problem may be related to the phone screen and a repair of the screen may solve the problem.

  You will first need to isolate the problem to see if it is software or hardware related.

  I would say to backup the iPhone via iTunes or iCloud and restore as a new to test and see if the problem persists. If so, its more than likely the screen of the iPhone. Hope this helps

• MacBook Air randomly fades everything down

  Yesterday my Macbook Air has randomly started dimming all the way down to the lowest setting.

  The screen is always on (I can barely make the content). If I hit the drive 'down' a couple of times I can then use the 'up' dimmer to return to normal brightness. However he then randomly will drop down to zero once again.

  I use a second monitor (as well as the use of the screen of my Macbook Air at the same time) and only the Macbook Air screen decreases intensity, the second screen maintains brightness and conviviality.

  Reset the SMC could solve the problem.

• Screen turns black and shuts off when wakes up Portege Z830 - 11M

  Hi all

  Anyone know what could be the reason for the screen goes black and turns off when the laptop wakes up?
  The laptop is Toshiba Portege Z830 - 11 M W7HP, purchased in September.

  The problem started shortly after I bought the laptop, but gradually began with a period of 1-2 seconds black screen whenever I tried to wake the portable computer of fashion 'sleep'. He didn't look like a regular part "blackout" of the wake-up process so I just tried to ignore it, but it started to happen more often recently. It got really worse after two months of use and the black screen two or three times until I'm at the login screen. The error was also difficult to re-create because it was random. Sometimes, the screen went black once sometimes twice or just blinked for a fraction of a second.

  Yesterday, I worked during the day and at night it turned really bad. The screen went black several times, whenever I went back to work after a short break.
  I changed the laptop off when I'm done, but when I turned back on it in the morning, the screen was just black. I tried to use the touchpad, but it is only the screen on the gray.

  Can anyone suggest what to do?

  So finally that cannot start the laptop is Hmm normal?
  It would be interesting to know if this help:
  -Battery adapter and ac removal
  -Press and hold power button do this for 30 sec
  -Then reconnect both sides.
  Turn on the laptop?

  If this is not good enough, you're in trouble I guess its hardware related issue and in this case you must service help

• My screen goes white and freezes?

  My screen turns white and locks. I have to press the windows key and the menu comes with the background task bar. I have to then right click on the task bar and choose show desktop away from the white screen. How can I stop the white screen appear?

  Screen goes white, you mean it fades? It crashes because your computer stops responding. If this is the problem then there is a problem with your computer. It could be incompatible software that has a boot entry and starts up with your system starts and then freezes, it can also be a bad driver or the driver missing. The last thing that can be a family virus attack.

  What you can do: make a full scan of the system with your antivirus. If you have Microsoft Security databases, then it is updated and do the work, second search on windows update, the updates to the driver. If it is a software that gives you the problem, I suggest you to search to divert it on the internet and run it on your system and then put his newspaper here.

  You can also try to do a system restore to a date where your system has worked well. to use system restore go to the start menu and type restore and then click System Restore, follow these steps.
