iMac freeze then spinning wheel
My problem seems to be heat related. It all started several months ago. I discovered the vents at the bottom and rear were clogged with dust. Since then it has progressively got to the point all I can do is one app at a time and won't run bigger apps like iMovie and iTunes etc. I have to use smcFanControl with the settings at full speed to do anything. I upped the ram to 2 gig and updated to Lion. I am capable of disassembly but don't have an idea what is wrong. Power supply, Mainboard itself, or hard drive going bad. It will random freeze then I get the spinning wheel and its over.
Is this a good question?
