    iMac 2.16Ghz constantly freezing
    Hey guys,

    Just a quick one. Ive had my iMac about 2 and a half years and its been great. Lately though it has been freezing alot, and in the last month at least x10 a day. I thought it may be due to the heat of the machine, but its not that as it happened when the machine is cold. The graphics seem to be playing up aswell, for instance it has loads of line across the screen? ive searched for a graphics driver update, but their doesnt seem to be one? Ive even upgraded the RAM, no luck tho Is this a common fault? is so what can be done?

    Thanks

    Jay

    I used this video on youtube (as i said im no comouter geek)

    YouTube - Speed Up Your Computer In 5 Minutes - Video 1 of 3

    the guy explains it really well and it is very clear. You will find alot of stuff u never knew was there.

    Also try the usual defrag and disk cleanup methods.

    Your heart is in the right for helping, unfortunately we are using mac's and not Pc's. In conjunction to the issue above I am leaning toward the video card. And if for some reason if a "clog up" is at hand, disk utility and erase free space will gain more HD space. Again sounds like video issues.

    Certainly sounds like the video card, however, you could try resetting nvram and zapping the pram to see if it helps.
    Also, you could try something like Macjanitor, to run routine maintenance checks, and maybe do a hardware test, as this should show up any faults.

    I believe as unfortunate as it sounds, the video card and lcd consume the most power from the computer so if card is on it's way out, then yes game over. If interested I can send you a trouble shooting guide. There are indicator lights on the logicboard that can confirm proper correspondence between logic and video.

    I have exactly the same problem. I was working on everything and even had it to the apple service for two weeks - they couldn’t find anything related to the hardware! So it was definetly the software. I had to reinstall 10.5.6 - now its stable again, still experiencing some fractals and lines, but much better. Hope for a new driver or fix of the problem with 10.5.8...
