[QUOTE="GLPerugia, post: 1447800, member: 272877"] [b]iMac CPU temp[/b] Hi boys! I would to say I've similar problems with my iMac (20" 2,16 Ghz, late 2006 with 1 gb of ram). This summer was very cool, so, trying to prevent problems, I used a fan near the machine for "refreshing" it and also I often controlled the temperature with iStat: I tried to maintein the CPU temperature under 50° Celsius, and sometimes shut off the iMac. But it maked horizontal multicoloured lines on windows (no more than one per time) and sometimes it freezed and I needed to restart the iMac. On 20th of August, at the booting, I'd a surprise: the machine charged the background of desktop, the dock and the menù-strip on the high, but not charged icons neither folders on the desktop and it seemed freezing, whit classical rotating multicoloured ball (if I remember right). So I changed hd; it is incompatible with my iMac and also I tried with newer o.s.. I had no success and, instead, I verified that the trouble wasn't tha hd. I reinstalled the previous hd and I tried to reinstall the original o.e.m. Tiger with the greys disks. Problems didn't stop: when I inserted the second installing disk, the system freezed, remained the windows with the request of inserting the second disk and this was rejected. Other times I restarted the iMac, I only see this window. Now, the question is: in your opinion the problem could be the GPU, the logic board, the ram, or what? I'll have to "dismiss" my "loved" iMac? I suppose the cool could be damned something, but I'm not a technician or an engineer..... Another question: the GPU is on the logic board? If so, is possible to change it? what can I do to clean it or logic board, if necessary (I need particular tools to do it)? Many thanks for attention e for replay you'd make to me. [/QUOTE]
