iMac Keeps restarting repair – Repair Procedure

In this case, this is caused by a failing graphic card, which slightly desoldered itself from the board, causing bad contact. It is a common issue caused by excessive overheating. It requires completely stripping down the iMac and repairing or replacing the graphic card. We prefer the first option as it is cost-effective and quicker. A replacement graphic card for 2010-2012 iMac’s may cost around 1800$, while the repair is half of that cost.

It is very easy to write off these iMac’s thinking that buying a new one is a better option. However, there is a catch!

New iMac’s are not as reliable as these older models, which have prolonged life due to the better design as well as an excessive amount of available space inside. This plays a vital role in cooling down heavily clogged with dust iMac. Over the year they gather a vast amount of dust inside, which causes serious overheating issues with the newer thinner models.

We have a sophisticated equipment workshop with high accuracy microscope, ultrasonic cleaning bath, reflow machine, and tools for micro soldering to achieve high-quality logic boards repairs. With thousands of components in stock, we quickly locate and replace failed components!


Going back to our iMac we took the graphic card out and placed it into our GPU repair tool. It reflows the graphic chip under a concentrated heat, aiming to resolder those tiny solder joints.

Please note: This is not educational material. It is rather a showcase of the services we offer.
Therefore, it should be used as general guidance on what to expect of such repairs.
In case you have a similar device and need the repair, always rely on professionals. These are sensitive electronic devices, and small mistakes may cause irreversible electronic damage. Which may require whole part replacement for 2 or 3 times the cost.

Repaired, not Replaced!

We are committed to reducing e-waste in Australia. How we do it is by educating our customers on the repairability and longevity of their devices, as well as providing affordable iMac Repairs here in Adelaide.
Although our best intentions and hard work, this is not an easy task. Customers must accept that cost of high-quality electronic repairs, is between a third and half of the price of a new device. However, with the current trend of planned obsolescence in electronic design, we see more and more iMacs having shorter lifespans. To tackle that, while we do our repairs we target common planned obsolescence engineering design mistakes to ensure we extend the life expectancy of the iMacs we repair. Check some of our iMac Repair Cases to get an idea of the process.

That said, if we buy a new one or write it off via insurance, it does not guarantee that the new one will not meet the same fate as the older one pretty soon.
As matter of fact, quite often we see accidents reoccurring within less than 2-year gaps. If we can save 3000$ or even 1000$ today by repairing our faulty iMac is great. That’s an extra half iMac cost ready to be spent on another one when the time comes or our need for performance increases.
When that time comes is up to us to buy a new one or keep pushing the one we have, but delaying it by a year or three is always a good starting point and saves another abandoned iMac from polluting our one and only Planet.
