G5 locking up, random screen pattern lock ups

Alright, this is actually my brother's computer, which he's had for at least a year and half, with no problems. I just recently started using it to play a computer game, World of Warcraft. The game ran smoothly with no problems for a couple of weeks. Then, some graphical problems started showing up out of no-where and eventually, within the next week led to the game and computer locking up randomly, requiring a manual restart. The fan in the back of the flat panel would get loud sometimes when this happened.
Now the comp freezes up whenever I even try starting up a game, not just warcraft, but will play videos just fine. (I already asked about the problem on that game's tech forums and they looked at the system specs and thought it might be a problem with this comp, saying that there was some recall on this model because of a faulty part.)
When starting up the comp, there are flashy, colorful streaks all over the screen, (probably 80% of the time)
Randomly when doing anything on this comp, a colored checker or bricklike pattern will cover the entire screen and require manual restart. It really makes it hard to do anything since we have to manually restart the comp a few times before the normal screen will come up. My question is: What might be wrong with this computer? Might playing that game have revealed the problem, since there had been no games used on this computer since now?

G'day Cory,
I'm starting to experience some of the same problems. When I boot the G5 iMac and its cold it will exhibit a heap of screen flicker in the grey screen and then boot normally. After that it boots to the OS with seemingly no problems ... except the screen refresh ... which leaves 'ghost' images all over the screen. When I Restart the problem seems to go away ... no screen streaks and lines at the grey screen, the screen refreshes as per normal ... and there are very few application hangs.
What I suspect is that since I have the original 20" 1.8 Ghz G5 iMac the resistors and/or motherboard have a fault which Apple acknowledged nearly a year back. It was common on PC's also .. hey who wants to spend 10 cents on a resistor when you can get the 'same' thing for 5 cents.
Apple announced a free repair program for this fault, so if that is what's the problem you (and I) should be able to get the puppy repaired free of charge by taking it into your nearest Apple dealer and letting them do their stuff.
I'm also covered by an AppleCare policy (hey, I had the DVD SuperDrive fail on my G4 Mac about 2 years into owning it - so figured better safe than sorry) ... but I figure this puppy will be repaired under the repair policy that Apple made known.
Regards,

  • Screen problems - black screen and lock-up (plus HDMI issues)

    Hi, I'm not sure if these are related to the same fundamental issue, but they are both serious problems that need resolution.
    I have a new mid-2012 MBPretina.  I am on all the latest updates (10.8.2).
    The first problem is the most recent, and the most serious problem.  Since I updated the Java a couple of days ago I've been experiencing random black screens and lock-ups.  Essentially, what happens is that sometimes when I perform an action (opening an app, clicking a link on a webpage, performing other kinds of in-app actions, etc.) the computer screen will go black.  About half the time I can, through my own memory, try keyboard combinations to quit or force quit the most recently used app (the one where the action was just performed), and I will get some glimpse of the underlying apps, while the menubar and other areas will remain black until I move a window on top of the black space.  Sometimes no key combinations work and I am forced to perform a hard restart with the power button.  This is a serious issue, obviously, since I will lose current work/progress in my apps.  I'm not sure if this is because of the new Java update, or has to do with something else, but it started happening shortly thereafter, over the last 2 days.  I work most of my waking day on my laptop, and this "black screen of death" has happened about 5 or 6 times a day.
    The second problem I have been experiencing since I starting using my MBPr with external HDMI displays in August/September.  The problem is that I will plug the MBPr into an HDMI display, the screen will temporaliy go black, and then bring me to the login screen (as if it's crashing, albeit softly).  This happens about 1 out of 4 times nowadays.
    How can I fix these problems, especially the first?

    UPDATE:
    Clearly there's a problem because a third of the way through a clean reinstallation from scratch it black screened again. Hmmmm.
    Now this is not good. Problem is I can't rule out potential updates from Apple that might have caused this either.
    The search for solutions continues.

  • I forgot pattern lock on my Sony Xperia Z1 and i need it back

    Hello,
    on my sony xperia z1 phone i forgot my pattern lock. I can't use the Forgot Pattern Lock because it uses Wifi conection which i can't connect to...(my screen is locked) I want to hard reset it somehow but i tried allmost every method on the internet but none of them were working I tried holding the volume up and these things....but as i said it won't work for me. Can anyone please help me? THANK YOU VERY MUCH

    In order to fix this you need to perform a system repair
    Switch off your phone and unplug from Pc (Hold volume up and power for around 10 seconds)
    Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the onscreen instructions - When prompted connect your phone still switched off holding volume down or back button - This should start the repair or reformat process
    If you are using Windows 8/8.1 or a 64bit operating system then adjust the settings for PC Companion and run in compatibility mode and chose Windows 7 or XP

  • I cannot receive phone calls or messages when iPhone screen is locked

    Hello,
    i have an iPhone 5.
    i Am unable to receive phone calls or text messages when my screen is locked. When I unlock the screen the missed call doesn't even appear so I have no idea anyone has called me. Text messages come through at about 12:30am every night.
    i Have tried EVERYTHING I could find in forums and Apple trouble shooting. This is my last resort other than sending it to Apple.
    iit is as if "do not disturb" is stuck on, but it isn't.
    i Have tried:
    changing all all do not disturb settings.
    checked call forwarding etc.
    checked mute
    my silent button is not on.
    i have reset every setting and then even reset the phone and manually transferred everything back onto it rather than restore It from previous back ups.
    oout it in recovery mode.
    i Have no success with any.
    the weird part is when I first lock the screen and try to call it, it does ring. But if I give it a minute or more it won't ring.
    does anyone have any ideas or anything that may help?
    PLease, please, please

    I Have also checked blocked numbers and swapped SIM cards from a completely different carrier so it's not the carrier either

  • NG6 pattern lock problem.

    Is anyone else having the problem of not being able to interact with their phone after the NG6 update with pattern lock enabled? On the first unlock my phone takes me to my home screen but does not respond to touch. If I relock and then unlock again it will respond to input. This is super annoying. This patch seems to have broken more than it fixed.

        I'm sorry to learn about the issues you're having with your phone after the update MechancialFox. We certainly want to do everything we can to get it up and running again. Have you tried Safe Mode? If not, please use the phone in Safe Mode http://vz.to/1ldHnPU and keep us posted.

  • Solution for a course going to a black screen and locking up after a while (20-30 slides for me)?

    The LMS is Saba and I'm using Captivate 6.  I am testing the course in production.  The course goes to a black screen and locks up.  The first time was at slide 28 of 55 which is a widget and the second time was at slide 20 of 55 which is a multiple choice test item.  I'm not sure if the type of slide I'm trying to advance to matters but I want to give as much info as possible. The issue seems to be random since I was first able to get to slide 28. 

    With LMS issues you should always test the same project in SCORM Cloud before you blame the project.  If SCORM Cloud shows the same issue, fine, blame the project.  If SCORM Cloud has no issue with it, get in touch with the LMS vendor.  It may be that they need to update some component of their SCORM Player software.

  • A500-02F - Locking up random

    A got a new Toshiba A500-02F and now it seems to be locking up now and again. seems to do it randomly with in and before login to Windows 7 64 home prem, I'm running a windows drive check right now, memory 86 later, anything else to check before contacting the store that stole me this gem?  It's the second time it's done this but it's worrying me now because it just starts getting slow and locks up.
    Today it locked up on the startup screen at user login.
    5:28pm update, ran a scan disk and found nothing wrong, so I ran some virus software and spyware apps, Malwarebytes' Anti-Malware, SUPERAntiSpyware Free Edition found nothing but did scare me when the computer would scan but the screen after 30 or so mins would go black and then I couldn't get the notebook to come out of sleep mode. turned all of the sleep mode stuff off and the scans ran fine but shouln't there be a setting for it to not go into sleep mode if stuff is happening? or will I have to turn that off everytime I scan my system?

    ya i'll give that a try the bios update but I also noticed something else odd. it started randomly starting media player on start up. every now and again Windows Media player starts on start up. but then sometimes it doesn't do this. I have my labtop connected to a monitor and a wireless keyboard and I am thinking it maybe one of those Multimedia keyboard buttons that's loading it. or miss loading it in this case. but not sure.
    I got the blue screen again last night, third time it's done this.

  • IPhone4 making random calls when locked

    The first that I knew about my iPhone4 making random calls was when I received a call from someone I hadn't spoken to (or tried to ring) for at least 2 years.  He said that I had called him.  I disagreed as my iPhone had been in my pocket for some time.  I had the screen locked (locks automatically after 1 minute and needs a passcode to unlock it).  I had not touched my iPhone for several minutes AT LEAST and had not even looked at this person's details in my Contacts for at least 12 months.  I checked my Contacts to see whether his details were showing as having been recently viewed in Contacts - no they had not.
    I keep my phone updated, usually updating to new software within a day or so of a notification.  The software was up to date.  That was about a month ago.  In the last few days my phone started making voice dialled calls to random numbers while in my pocket.  Again the screen was locked and I only became aware of the problem due to the phone "speaking".  Again, the phone was locked and hadn't been used for some times.  It still needs a passcode to unlock it.  I turned the phone off and restarted it after it had been off for about 20 minutes.  Shortly after that it made another random call.
    I used to work for a Telco and I always disbelieved customers who said that they had not mt made calls that they had been charged for.  Now I'm starting to wonder...
    Yesterday my iPhone (again keypad locked and in my pocket) started playing music.  I could not get it to stop or even unlock my keypad.  I had to shut it down completely.
    Help please.

  • Slide lock on home screen has disappeared

    This is about the security feature you have to use each time you start up the Droid X -- i.e., the image of the combination padlock that you drag to the right.  That feature disappeared a while ago (before I upgraded to 2.2) and hasn't come back.  So how do I get it back again?  I've gone through the security settings and can't seem to find that option.  (Note that I am not talking about the password lock or the pattern lock, just the simple slide lock.)

    If slider was disabled at time of update the slider remains disabled because there isnt any options to enable it, only solution it to hard reset. Use the instructions here: http://community.vzw.com/t5/DROID-X-by-Motorola/Minimize-Droid-X-Issues-After-Froyo-Update/m-p/296586#M11211  also heres a little reading material that I got from Motorola about this subject... http://motorola-global-portal.custhelp.com/app/answers/detail/a_id/57221/kw/disable%2Bslide%2Bunlock%2Bon%2Bfroyo/p/30%2C6720%2C7500%2C/session/L3NpZC9uMVE5alJiaw%3D%3D/p_country_code/US/p_reference/moto_integration.php.
    Notice the statement under photo states "Screen lock for DROID X Froyo users (SW version 2.3.15) is a permanent feature.
    You will not have option to turn "Screen lock" (the simple swipe from left to right when display is dimmed) either OFF or ON your handset."

    IPhone black screen does not show anything, but I can hear that the device works. I hear the lock open the screen and hear the iPod but the screen remains black!!

    It's happened to me before as well. Try holding both lock(top right) and home buttons simultaneously until u see a slight flash of wight then just reboot it normally. If that doesn't work try restoring your device from itunes

  • HT4085 How do I lock my ipad screen so the swipe action and side button on screen don't work? My cats do these things and the game disappears.

    How do I lock my ipad screen so the swipe action and the side button on the screen do not work?  When my cats play a game on my ipad, they regularly swipe the screen and push the side button and the game disappears.

    The button on the top that you use to lock and unlock or put to sleep is the power button.  The button lower center of the screen is the home button...can be used to also wake from sleep and switch to the base home screen.
    Good to hear you are now able to lock rotation, even if you are not sure how you did it
    If you go to the iBook icon, tap Store in the uppper left side of the screen, you can search for the iPad User Guide...a free download that will place the guide in your iBooks library as a great source of background information.

  • How do I restore my ipod to factory settings, but I have a passcode lock, and my screen is broken so I can't type in my password when I connect to itunes?

    Okay so I have had my ipod 4th gen for almost 2 years buy the screen has fallen out of the back casing, (I bought it as refurbished) and I am trying to reset it to factory settings, so when I get a new one I can register my device on apps/games since some apps require that you can only register on one device, but I think the thing that connects to the screen is ripped so the screen won't turn on and I can't physically touch it. What I want to know is how can I restore it with me not being able to type in the password lock since the screen is broken?
    or is there a way to disable the passcode lock through the computer?

    Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.
