I wonder if anyone can help me. I am not very technobod and there are progressively awful problems on my Mac until it is now so slow.

I need to fix it before it dies altogether, or I throw it out of the window.....



Thin black lines randomly appearing across the windows.

Ghosting of windows, they leave another version when moved.

Sometimes windows just white out in areas with scribbly lines like pretend text.

Sometimes windows have large bare patches all of a sudden or go see through

Programs keep just quitting for no reason.

The whole computer just freezes every now and then. Sometimes it waits and returns, occasionally it crashes completely.

It is really painfully slow and can take me considerable minutes to open a new window or get something else up on screen.

The tool bar sometimes goes all skeletal with no background.

Loads more silly things like this... all random.


It is driving me absolutely potty. It's only used by me doing emails, filing pics, designing jam labels, letters, going on forums and things. I don't give it loads to manage unless I'm doing something spectacularly stupid. This computer ought to be big enough to run a design studio....


I have tried mackeeper, found it gave more problems than it solved, and uninstalled that, I've tried Clean my mac and only cleaned some, I left the universal binaries and the Caches alone. I then tried Onyx and fixed some listings (I kept the report) and cleaned up the caches in that, then restarted.


It is now even slower than before I started fixing it, and all of the problems are still here. I've got time machine for back up.


What can be going wrong? Is anyone able to help over the next couple of days?

    First thing is to remove MacKeeper from your computer, in addition you probably do not need Onyx either although it may be OK. OS X does NOT require third party utilities to maintain it, if you used to use MS Windows where that was necessary it's not required for OS X. OS X does a good job of caring for itself and other utilities are built into it if needed. I would then recommend re-starting the computer in Safe Mode, this will clear some caches. Try this first then tell us what happens.


    Also PLEASE tell us what system  you have. It's difficult to troubleshoot a computer without know at the minimum what version of OS X it's running, the computer model etc. You can fill out your  profile in Your Stuff (upper right of this screen) - Profile and then complete the fields as needed.

    At this point it sounds like you may have an internal hardware problem.  I would recommend booting from your Original Installation Disk that came with the computer and run AHT (Apple Hardware Test) or even the Extended Apple Hardware Test to try and diagnose the failing component.  It may well be the logic board is giving up the ghost.


    Hope this helps

    I have to agree that it looks like hardware. Time to run AHT in Extended Mode if needEd 2-3 times to find errors.

    I am having to answer you now on an iPad because I cannot get a window to open any more on my pute. I opened it in safe mode and that was ok, but now it will not let me get into this forum at all. The window opened but when I pressed the mouse, the little whirly thing just has been going around for over two hours now. I cannot stay on this as my son needs it for his exams. I will do the other things you suggest and I will return. Thank you peeps.

    Back again on the iPad. I had to do mummy stuff all over the bank holiday weekend so not able to be online. I am having trouble locating any relevant disks. I have a feeling the mac came pre loaded, but I am still looking. The computer itself spends hours hunting for any window I request and then either firefox or safari just bomb out on me saying something about it having trouble writing a script. I can go and read it again if it is of use. It still switches on, but not much else. I know that if I take it back to PC world, they will just tell me to buy a new one.


    If it is a hardware problem, is that the only solution?

  • Mumonmymac Level 1 (0 points)

    The only discs I can find so far are IMac Mac OS X Install Disc 1 and 2 for version 10.4.7 Which isn't brilliant, but better than nothing. I will keep hunting to see if I can do better than that.

  • Radiation Mac Level 5 (4,645 points)

    Those are indeed the Original Installation Disks that you need to use to run AHT.  Go for it.


    Hope this helps

    Yes those are the oringinal (and very old) Install Discs, please run Apple Hardware Test in Extended Mode. You can find instructions by clicking Hardware Test.

    you are such lovely people, helping me.

    Okey dokey. I'm at the computer and of course firstly the disc won't go in the slot whilst it is off. So I'm attempting to restart it, then insert the disc, then turn it off and reboot from the disc by pressing C.

    I may be another while......

  • Mumonmymac Level 1 (0 points)

    Whoohoo. there was a boop noise and a vroom and an apple is appearing there and lots of disc movement.... So I think we are off.

  • Mumonmymac Level 1 (0 points)

    I nearly freaked because it asked me to reinstall. Then I saw I had a choice, so I'm restarting using the disc and will press D.

    I love you guys, the right symbol has appeared and it is running an extended testing now.........

    Alert! Apple Hardware Test has detected an error.

    I presume that isn't good. So I shall google it.
