imac frequent crashes
Hello,
I have a 3.06 GHz Intel Core 2 Duo iMac with 8GB memory running OSX 10.9.
My machine frequently crashes/freezes, often with multi-coloured dots on the screen. All I can do at that point is switch it off via the button on the back. There is no apparent pattern to what is causing the crashes. I have tried using a different browser and have disabled applications such as Spotify from automatically loading on start-up. Below is the error report from the last crash. Any ideas/suggestions ?
