24"Aluminum iMac, of mid-2007 vintage
Out of AppleCare?
running games on it in Windows - and promptly encountered video artifacting.
Fully updated Windows and Boot Camp?
No issues when running OS X?
After much research, I found that overheating was the cause of the
problem. Installing fan control software, like smcfancontrol and
Input Remapper allowed me to crank up the fan and prevent video
anomalies. Lately though, the wireless began cutting out and I
noticed high temperatures. I raised the fan speed, and the problem
went away for now, but I seem to have some "thermal creep"
:(
I assume this is due to dust build up on the inside of the iMac, in
addition to whatever problem originally existed (too much thermal
paste, perhaps?)
Assumptions are never good.
The dust supposition is quite possible. How clean is the
environment? Smokers? Pets?
The thermal paste guess is iffy. If that's the case then you'd see
more issues, even when running OS X.
Have you tried doing the basics, like resetting the power manager?
The obvious solution is to blow out the inside of the iMac and
perhaps apply new thermal paste to whatever heatsinks lurk on the
inside. How difficult is working on the inside of an iMac?
Cleaning the inside of the iMac certainly sounds like a good idea.
DO NOT muck with heatsinks and paste unless you POSITIVELY can nail
the problem down to such an issue.
I have worked on dozens, if not hundreds, of PCs and PowerMacs, but
working on laptops always makes me twitch. How much potential is
there for error in disassembling, blowing out and re-pasting an
Intel iMac?
Sites like ifixit have great instructions about how to open up and
work in the iMacs. They even sell good suction cups. Just be
careful and BE PROPERLY GROUNDED and you'll do OK.
AGAIN: Don't touch the paste etc unless you KNOW that's the problem.
As an aside, how much would it be worth as I sold it as-is as a fixer-
upper?
Check the closed auctions on eBay for your exact configuration. That
should give you a general idea. Also search our Swap mailing list
archives.
