Hey. I have an older iMac, 2006 white version, running leopard. I am one of the many people who experience semi-frequent freezes which forces me to manually power the machine down. After much research it seems everyone has diagnosed the problem has hardware, specifically the graphics card running hot. I installed smcFancontrol and have ran it for four to five months. Since then I have experienced maybe 4 or 5 freezes, but the freeze occurs while doing nothing "heavy", just browsing in safari or chrome. my question: Has there been any updated or new information concerning this problem? I have scanned the web a little and can't really find anything really recent. The most recent article/discussion i have found is roughly a year old. Any input would be appreciated.
