Odd graphics problem, eventually leads to forced reboot, or even BSOD

I am fairly certain that this is firefox related, or plug in or maybe compatability issue, however I'm getting weird blocky graphics. which occasionlly seem to begin from a flash frame within a page, but I can't say this is 100% the cause. It looks like small multicolored boxes that are in odd patterns. and causes other odd graphics, it gets worse the longer I let it set. One time for the heck of it I rolled the scroll bar up and down about 10 times very quickly and it caused a BSOD. These odd graphics do not ever appear if I don't open Firefox (have been using IE today) but they do not disappear if I see them and then shut down Firefox. Usually I'm forced to reboot the computer because they take over too much of the screen, I can't see anything. It does change though, when I move windows and such, they are not limited to the Firefox window and spread to the empty desktop too.

Checked settings for Flash and I couldn't find hardware acceleration. 1st tab on Settings Manager is "Storage" and gives options for saving information on my computer ie. "Allow sites to save information on this computer"
2nd tab is Camera and Mic "Ask me when a site wants to use the camera or microphone"
3rd is Playback "Ask me when a site wants to use peer-assisted networking"
4th (last) is Advanced "Check for updates automatically" a couple other settings but no acceleration.

  • Major graphics problems, 7300 GT

    Hello.
    I have a white 24" iMac with the Intel Core 2 Duo and the 7300 GT graphics card. Upgraded to Leopard and 3 GB RAM.
    About a year ago I started experiencing graphical problems while doing things that involved a lot of GPU activity, like playing a 3D game in Windows. Textures would become discolored and corrupted to the point of not being able to play the game. After letting the computer sit for a while it seemed the issues would be alleviated, but the same symptoms would recur after running the game for a while.
    I eventually began to notice similar issues occur during much less demanding usage in OS X. Graphical glitches would appear on the desktop and in active windows. When the glitches got especially severe the display would freeze and the system would have to be rebooted to be usable again.
    This seemed like a heat related issue, to me. I took the computer apart and cleaned the dust out all of the ducts and fans, but it didn't seem to help at all. I installed an application called smcFanControl, which allowed me to force the fans to run at a faster speed. While running faster, the glitches stopped occurring and the system would no longer freeze.
    Things were okay this way for several months, but now, even with smcFanControl set to run the fans as fast as they can go, the glitches are beginning to occur again. Entire windows become discolored with a cyan hue, and random artifacts show up in random places on the display.
    Here are some shots to demonstrate what is happening:
    http://horseface.org/iMac/1.png
    http://horseface.org/iMac/2.png
    http://horseface.org/iMac/3.png
    iStat pro doesn't indicate anything shocking as far as temperatures go. During all of this glitchy madness, here's what it's showing:
    http://horseface.org/iMac/temp.png
    Note that the fan speeds are way high, but, again, that's because I'm forcibly raising them with smcFanControl. Interestingly, though, even when I'm not running smcFanControl, the temperatures seem to hover in a safe area. In spite of this, I'm almost certain it's a heat related issue. When I first installed smcFanControl and increased the speed of the fans, the iMac went from freezing and glitching on a daily basis to totally normal operation. There also appears to be a direct correlation between intensive usage and the glitching/freezing issue.
    I have already installed all of the seemingly relevant OS X updates that I can find along with all of the other suggested updates. Nothing has helped, aside from smcFanControl.
    So, my question is, what can I do about this? My computer is no longer under warranty. I'd rather not have to take it to Apple and have them charge me for the initial consultation and then whatever hardware replacement is required along with the cost of out-of-warranty service. I have already opened and disassembled this computer while trying to clean it. While it was a very daunting task the first time around (I really wish this iMac were as nicely designed internally as the first G5 iMacs!), I'm comfortable enough to go ahead and do it again, if necessary.
    My educated guess here is that there is something wrong with the video card. Perhaps the onboard temperature sensor is bad, and that's why it's reporting safe operating temperatures but is behaving as if it were overheating? I'm not really sure.
    Would it be wise to try to replace the video card? This seems to be the obvious next step to me, but, unfortunately, the prices I'm finding for the replacement parts are pretty outrageous. ApplePalace.com lists the 7300 as $188 and the 7600 $231. Is there anywhere I can get a replacement for less? Is this even likely to fix the problem? I really don't want to make such an investment and have it turn out that it's not going to help.
    I don't know what to do. Any ideas or advice would be greatly appreciated. Thanks in advance.

    Have you tried running Apple Hardware Test?
    Your guess is most likely correct of it being the graphics card. I have a friend with the exact same computer same problem. It's not an over heating issue. A component is supposed to operate within certain values and certain temperature ranges. If a part has gone bad or is going bad it may not be able to produce those values at the temperature required. Maybe it can still operate within spec at a lower temperature. Even though temperature appears to be the indicator this does not actually mean the device is over heating rather the part is failing.
    I have only been able to find one website that you can purchase the replacement graphics cards for this particular iMac and yes it's a bit pricey. My friend was quoted by the Mac Guys for about $250 including installation for the 7600GT card. Replacing the graphics card is really your only option unless you want to junk it and buy a new machine.

  • Yosemite graphics problems - strobing screen

    I installed Yosemite and immediately starting having graphic problems.  The screen strobes on some screens.  This is like most OS upgrades there is no obvious improvements it is just different and cause more problems. There are a bunch of programers at these companies trying to justify there jobs and screwing up all of the users.

    Try a restart.
    Do a backup, using either Time Machine or a cloning program, to ensure files/data can be recovered. Two backups are better than one.
    Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.
    Isolating an issue by using another user account
    Try booting into the Safe Mode using your normal account.  Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear and again when you log in. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don’t do them all at once.

  • 2008 Macbook Pro won't wake up - can't force reboot

    I have searched the interwebs high and low on this one for a long time and haven't found a solution, I post now in desperation as I need my mac urgently.
    Every once in a while my mac will not wake from sleep, the problem has persisted now for over a year and even a trip to the genius bar didn't help.
    I've read many a post on macs not waking up, but in all of them a force restart is possible. Not here, in my case the mac will simply not wake up no matter what, until hours or sometimes days later it simply wakes up again like nothing happened. Last time it occurred I took it to the genius bar (a fair hike for me) and sure enough, it woke up first time. They ran all kinds of tests and nothing was wrong.
    I've tried all the zapping of prams and resetting of power systems, I've tried every key combination I can think of, whilst some seem to do something - make the light flash or turn off, get the fans chugging, make little 'computer' noises etc, it just never wakes up. It never shows up on the network, it never makes the startup chime or any other system noises, it really is in a state of hibernation.
    If I close the lid, the light on the front glows bright, if I open the lid it gets dull. If I force shut down it goes off completely. But hitting the power button brings it back on (to dull). Holding the power button down to force reboot causes the light to flash rapidly but then nothing happens.
    Removing the battery, letting the battery drain, or unplugging the magsafe makes no difference.
    All I can ever do is wait, and wait, and so far each time it has just eventually come back to life when it was good and ready, usually around two days later.
    When it does, the screen I left is usually still there, just how I left it, only its black and white and a little progress bar chugs along for a few seconds and then its all back to normal, even apps I left open are still there running, like it was really just asleep the whole time.
    If anyone has any ideas at all I'd be most appreciative. 

    Well, if You or Genius did all things like PRAM, SMC reset, etcetera, why not read threads about the sleep/wake issue? There you'll see that this is not a uncommon problem.
    I solved it by setting the hibernatemode to 0 (zero) via a Terminal command:
    sudo pmset -a hibernatemode 0
    sudo nvram "use-nvramrc?"=false
    Then you can get rid of the sleepimage (pagefile) like this:
    sudo rm /var/vm/sleepimage
    (sleepimage is as great as your built-in memory (in my case 8GB)).
    There is even a little program in the Appstore to do this (and more) for you:
    Smartsleep.
    Try this.

  • Apple Mobile Device Service failed to start which eventually leads to windows error 193 which never goes away no matter what I do  and the dreaded

    Mid way through download of I-Tunes after clearing every Apple program from my computer I get "Apple Mobile Device Service" failed to start message.  Eventually leading to Windows error 193 (error 7).  How do I get Apple Mobile Device Service to start so I do not get error messages and failure of I-Tunes to install?

    If you have a 64-bit machine, then try the "for older video cards" version...
    For general advice see Troubleshooting issues with iTunes for Windows updates.
    The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
    The further information area has direct links to the current and recent builds in case you have problems downloading, need to revert to an older version or want to try the iTunes for Windows (64-bit - for older video cards) release as a workaround for installation or performance issues, or compatibility with QuickTime or third party software.
    Your library should be unaffected by these steps but there are also links to backup and recovery advice should it be needed.

  • W7/64-bit on W500 - Switchable Graphics problem

    Hi,
    Did a clean install Windows 7 Ultimate (64-bit) on my Thinkpad W500 (4062-3CG).
    Having problem with "ThinkPad Switchable Graphics Driver for Windows 7".
    ATI driver won't load, so default Intel chipset is used with poor graphics as a result.
    I have also tried "Windows 7 BETA Drivers and Utilities" with no luck.
    Yesterday the graphics worked for a short period of time, that was after remoting my Thinkpad with RDP? very strange. But after reboot graphics was back to non functional again.
    Any ideas?
    TIA
    Johan

    Did you apply Lenovo driver packages in any specific order? Don't really understand what I missed?
    My plan was to do a "clean" W7/64 install and after that run ThinkVantage System Update 4.0 for latest drivers.
    In my case ThinkVantage System Update 4.0 could not start without Access Help for Windows 7 installed, that was the first dependency problem.
    However, after that ThinkVantage System Update 4.0 run successfully and everything works fine but the ThinkPad Switchable Graphics Driver for Windows 7.
    The ThinkVantage System Update 4.0 applied latest updates for everything including the BIOS. When I try to run BIOS update separately for getting around the graphics problem it says BIOS version is OK and no update needed.
    Tried to disable Switchable Graphics in BIOS-setup using Discrete but that does not fix my problem?

  • Photoshop CS4 graphics problem solved in Windows 7 -64 bit

    I recently spent several days tracking down why i was getting odd graphical behaviour in CS4.
    Often, while using the polygon lasoo tool andother tools, the screen woud jump and the selection would stop in mid-stream.
    I also noticed other odd behaviors.
    the solution was to turn of the AERO effects by right clicking on the desktop, choosing personalize and choosing "classical theme".
    Prior to this problem, when I started the latest premiere pro, I couldn't access the tabs in the choose settings fields. After talking to tech support, we found that I had set my default font size for Windows 7 to 125% of normal, so i could see the high res screen better. Resetting it to 100% by right clicking the desktop choosing settings, advanced, cleared up the problem.
    I hope this helps other users avoid similar headaches.

    Thanks for posting the information.

  • 24'' iMac 2006 graphic problems

    I have an old iMac which I am planning to give away for free. It is a 2006 24 '' iMac with 2,16 GHz IntelCore duo processor. It had originally 1 GB RAM, but has now 4 GB RAM installed .
    The latest OS it had was iOS 10.7 Lion, and there were some graphic issues where parts of the screen was really odd.
    I cleared the HD and did a clean install of iOS 10.7 Lion using the recovery HD partition, The installation proscess was uneventful, and with no graphic disturbances. But as soon as I started using the machine, there was again graphic problems. I also got som of the "You need to restart your computer...." messages.
    I then again cleared the HD and did a clean install of iOS 10.6 Snow Leopard from a SL DVD. Again an uneventful installation, but the same graphic problems when using the machine.
    I repeated the proscess and did a new clean install of iOS 10.7 Lion, this time from an installation USB stick I made some years ago. Same thing.
    I then cleared the HD once again and did a clean install of iOS 10.5 Leopard from a DVD. This time I was really optimistic because everything looked so good. But after using the iMAc for some minutes, there are again graphic problems. It seems the problems are less with Leopard than the other iOS I have tried. SOme times the screen looks normal, sometimes there are horisontal stripes across the screen, and sometimes part of the screen is really disturbed.
    During the installation proscess there are no graphic issues.
    I have repaired permissons, reset PRAM and using Disk Utility to repair the HD shows nothing wrong.
    Does anyone have any ideas what is wrong? Is it a hardware or a software problem? I do not want to use much money or much time on this, as this is really an iMac I do not use anymore.

    It's not software. It's consistent with a graphic card/logic card problem.
    I have an iMac, and I'd be obliged if you could satisfy my curiosity. What kind of computing have you done? Pretty routine web browsing and email?  Gaming and video editing? Have the temps gone up very high at any time while using it? Did the problems happen after your latest upgrade? Have you tried downgrading the OS?
    Thanks!

  • New iMac freezing, showing Graphics problems and Wifi Problems on 1st Day

    My sister just received her new iMac - 20 inch - 500 GB drive.
    I started seeing problems during the download of the FIRST software update from apple. There was a black box in the lower left corner of the software update window where it should have been grey (or metal).
    On reboot, I also occasionally show weird flickering graphics in the lower right of the login screen.
    My new iMac also frooze about 4 different times during the installtion of various updates during the first 4 hours of use. Mouse and keyboard would not work. Once it frooze at the login screen after clicking on the user name.
    I also had wifi issues. After three hours of use, my STRONG wifi connection was lost. Moreover, I could not see any other wifi stations. (normally I would see 5 other wifi access points from my sister's neighbours). After reboot, the other wifi access points would appear including my sisters but I could NOT connect to my sister's wifi access point. It said I had an error. I checked the keychain and it showed the right key/password for my sister's wifi AP. I had to run Mac Network Diagnostics and reset wifi to get things working again.
    It sounds like a sick iMac. I know others have experienced freezing. But given all these problems, should I ask for a new imac?
    Rob
    P.S. My sister got AppleCare as well. Maybe that was a good thing...

    I had a long chat with Apple Support. It would appear that Apple's policy is not replace the computer unless it can be determined that it is a hardware problem (even though my problems started to appear right out of the box before I even had a chance to download any updates). According to the Apple product specialist, sometimes there are bad installs of the OS at the factory.
    Apple wanted me to format the drive and reinstall the OS.
    Fortunately, I did not have to reinstall the OS! I started to see graphics problems when I was asked to run the Disk Utilility off the Install DVD (so I could format the drive). So clearly there was a hardware problem.
    In retrospect, I really wish there was an Apple Store nearby to buy Apple computers. I am sure the store manager would not ask me to go home and reinstall the OS etc and try again when the computer doesn't work properly out of the box.
    Those who have Apple Stores nearby do not know how lucky they are!

  • Green-Pink horizontal lines, Graphic problem, late 2011 with my Macbook pro

    I have late 2011 Mac book pro model (bought from USA - living ın Turkey) Last 2 months I have problem with graphics, I try to reinstall and reboot my machine but it didnt work. Generally It is happening when I am trying to use Adobe programs, so I am thinking problem might happening because of heating problem maybe. But I download fan temprature and it seems fine (even I feel so hot )
    My screen is going like this http://imagizer.imageshack.us/a/img26/9898/screenshot20130201at758.png (image taken from forum) sometimes with pink-green vertical lines. Then I am trying to restarting, after a few trying It seems normal again. I read lots of complains about this in the forums and sites, my warrent is finished, so I am really worried about fixing prices ... There is no any card replacement program Call from Apple yet, right? Doı you think they can accept their faults...

    You likely have the problem as discussed here -> https://discussions.apple.com/thread/4766577?tstart=0. It affects 15" and 17" 2011 models. Take a look at the thread and see if you've similar symptoms.
    If that long, long thread seems to be addressing your concerns, then you've one of two choices to make: 1) take the machine into Apple and have them replace the logic board, or 2) have your GPU BGA reballed.

  • 10.6.5 update - 27" iMac, Radeon 5750 odd graphics behaviours?

    I updated my new iMac 27" to OS 10.6.5 today and have seen some odd graphics behaviours.
    1. Dock icon for Activity Monitor becomes transparent. Running AM, hidden showing CPU history
    2. White rectangle at bottom of expanding folder (list view)
    3. OK Button blue/white check mark pattern when configuring VPN. GUI feels "slow"
    I updated using the Software Update tool; noticed these issues and re-updated using the Combo Installer; no change.
    Any ideas or suggestions? Is this just me? I have a MacBook -- no probems at all!

    N Gallagher,
    I had the problem earluer, but it got far worse with 10.6.5, however, I fixed it by updating my wacom tablet driver.
    It wasn't the system update, but an old driver causing the problem.
    Resetting PRAM, SMC and permissions and all the other standard drivel people post is nice sentiments, but it should be clear that the problem is something else because that solution hasn't solved the problem for anyone.
    I have the sneaky suspicion that it's old flash and old drivers for most people.
    See my original post here: http://discussions.apple.com/thread.jspa?messageID=12570261#12570261
    BUT. If you have a Wacom tablet, for to their website and download the latest driver from September 10, 2010.
    That's all it took for all my graphics problems to go away.

  • Adobe Shockwave Player 12.1 and forced reboot

    Hello I work for a company with 8k computers and we use IEM (IBM Endpoint Manager) distribution tool. We started Adobe product patching in January and we encountered unexpected forced reboot on some Windows 8 computers. IEM creates installation scripts automatically and I have noticed that there are two installation files: sw_lic_full_installer.exe  and sw_lic_slim_installer.exe. I have performed some test with both packages and on one PC where I tried sw_lic_slim_installer.exe the FORCED REBOOT occurred. I have checked event viewer logs and found the following lines:
    Windows Installer installed the product. Product Name: swMSM. Product Version 12.0.0.1. Product Language: 1033. Manufacturer: Adobe Systems, Inc. installation success or error status:0
    Windows Installer requires a system restart. Product Name: swMSM. Product Version 12.0.0.1. Product Language: 1033. Manufacturer: Adobe Systems, Inc. installation success or error status:0
    Ending a Windows Installer transaction: C:\windows\SysWOW64\Adobe\Schockwave 12\swMSM.msi. Client Process Id: 220.
    The Windows Installer initiated a system restart to complete system restart to complete or continue the configuration of "swMSM".
    Could you please explain me when Adobe Shockwave Player updates force a reboot? Unfortunately all updates are packed in exe files so I don't know any way how to suppress the reboot.
    Additionally after the installation of the patch we see 2 entries in the control panel:
    Adobe Shockwave Player 12.0
    Adobe Shockwave Player 12.1
    Can you tell me how to get rid of the Adobe Shockwave Player 12.0 entry?  Thanks in advance!

    I had the same problem on an iMac but managed to download and install shockwave 11, see Adobe - Webplayer
    There appeared a notice for incompatibility, but was able to continue installation. Apps (not requiring sw 12) did run after.

  • Safari Hard Hangs, Force ReBoot

    Anyone know what the deal is with safari for the last week or 2? I get completely randon hard hangs where I need to force reboot using the power button. Doesn't seem to be any specific site, and I've seen other postings on here about it.
    Was there any kind of solution posted, more than resetting safari, clearing java caches, uninstalling Windows Media Player, and checking the drives and permissions?
    Any help would be appreciated.
    Dual G5 1.85   Mac OS X (10.4.1)   1.5 GIG RAM

    Stephen,
    Welcome to Apple Discussions !
    There is nothing wrong with Safari.
    There is something amiss with your settings or maintenance
    on your Mac or Safari.
    Here are some recommendations & questions for you:
    1. Trash your Icons Folder:
    HD>Users>Home>YourName>Library>Safari -->Icons
    Restart Safari and a new folder will be automatically regenerated.
    (This folder saves favicons of all the sites you visit. Needs cleaning periodically -- or you can change that file's preferences to "Read Only"
    rather than "Read & Write." This will keep it from growing in size.)
    2. Check all three "auto" preferences in Safari, especially "Other Forms." Sometimes those lists gets very long and need pruning. (I turned all autofill boxes off, and have no problems.)
    3. Launch Font Book and check all fonts for duplicates. A duplicated font will have a bullet beside the font family and you can resolve duplicates by selecting the font and at the menu bar, go to Edit > Resolve Duplicates.
    Do this for each font with a bullet next to it.
    4. Do you have Speed Download, iGetter, PithHelmet, AcidSearch, Safari Enhancer or ANY other "internet enhancers?" Is Norton or Virex on there?
    If you're still having problems:
    Shut down your computer . . . unplug the computer, modem, and router, if you have one. Let everything sit for 2-3 minutes. Plug everything back in, start up your modem & router, then restart your computer.
    Hope this helps

  • Colourful squares graphics problem

    Hey folks,
    I've got a recurring graphics problem where on certain applications green and purple squares/lines begin to hover and flicker on the screen. Also, graphics on games such as Civilization IV are distorted, and also exhibit said squares. I've seen this happen on PhotoBooth, Coverflow, Safari, and image heavy pdfs on Preview. I've never seen them playing movies or Photoshop.
    http://img176.imageshack.us/img176/5051/problem2kj1.png
    What's odd is that I can screen capture them, and with them there, things still function properly (mouse, keyboard, applications). Also, sometimes they go away, and can be 'deleted' by moving a window around the screen to 'erase' them. Other times, they just accumulate. Usually a restart is required to get rid of them, but if I open the same application again, boom! Back again.
    I'm guessing, after reading on all these forum discussions, that it could be a graphics card error or something, but I was wondering if anybody else had any insight/answers, or advice about what to do or what to tell the Apple Support people down at the store/on the phone.
    Thanks in advance!

    An error like this, especially if it reoccurs frequently and/or causes crashes or kernel panics is usually a very good indicator of bad Video RAM. That's a hardware problem that will require Apple to replace your entire logic board (since the VRAM is soldered to the board).
    Take the computer to your local Apple store along with the photos you have of the problem. Explain the situation to the genius and he'll most likely send your laptop off for repairs.

  • Saved passwords disappeared after forced reboot of the system.

    As I said. After force reboot of the system the list of all my passwords was cleaned up. Bookmarks are ok. FF was closed, before reboot. Any ideas how to return them ?

    Hi Ishini,
    No problem. Firefox would not keep a back up of "key3.db" anywhere. So, if you want to recover your passwords, try to use the following tool.
    * [https://www.piriform.com/recuva Piriform Recuva]
    Just download the free trial and attempt to recover the "key3.db" file. Just point it to your Firefox installation directory.
    This should solve your problem, but there is no guarantee that the file will be there.
    So, if this helped, mark it as helpful, so other users who are facing the same or similar issues, can resolve their problem as well.
    Have a good one,
    Michael.
