"Everything Apple"? iMac issues

[elcorso]

I had a similar issue with a Mac Pro.

 

After resenting everything the problem didn't go away.

 

Solution:

 

Shut down.

Disconnect all the peripherals.

Disconnect the power power cord for about 20 minutes.

 

Connect the power cord.

Restart zapping P-RAM.

Connect all the peripherals.

 

Good luck!

I just vacuumed the intake.  Where is the exhaust slot?  Was yours a 2012?  I have to cut a glue seal, so I am a bit nervous, and don't have the right tool.  If I open it up, I might as well DIY replace the power supply.

 

Edit:  I found it -- all along the bottom edge of the chassis.

That's a bummer. I miss the OS, but I do not miss their hardware upon moving to the Darkside for DSD512.

 

I stayed at 256 and happy, I use a PC like NAA, but that's the closest thing to WIN PC I've come to.

 

A friend built a WIN PC for 512, but since he lives a long way from my house I can not compare the SQ. So i'm still happy 

 

Best,

PS/ Sorry Bill for the OOT.

I downloaded the fan control app and set it to read the temperature from the GPU PECI and crank when it gets warm.  So far, I haven't had a power shut-off since I did this (and vacuumed the air intake and exhaust ports).  So maybe it does have something to do with over-heating.  

 

More reason to clean the inside of your iMac. Most of the time even the fan blades are dirty...

 

We want it opened. And inside pictures, of course

I've opened up Mac mini and Macbook air, and (trivially) power-macs.  But the idea of using a pizza cutter to slice the glue that holds the glass and LCD onto the chassis is not something I feel like doing.  I would rather pay someone competent not to fuck it up.  I do most of my own bike wrenching, including hubs and bottom-brackets.  But there are some things I won't do, like wheel building.  A man's got to know his limitations.

 

 

 

You are right.  This side of the world sometimes we have to make crazy things, if we can't find a qualified and not too expensive technician.  We have two companies similar to Apple Store, but when you got a problem like this they want to sell you a new computer !

This may be why you didn't do to medical school if opening up a computer is too much...

 

If I were closer I would help.  Do you have a surgeon friend?

 

For an iMac you need a brain surgeon
