iMac Intel Repair & Upgrade
Bournemouth, Dorset & UK-Wide Service
Breathe new life into your Intel iMac. From SSD upgrades that transform performance to GPU repairs and screen replacements, we keep your iMac running at its best.
Intel iMac: Still Powerful, Highly Upgradeable
The Intel iMac era (2015-2020) produced some of Apple's most capable and, crucially, most upgradeable desktop machines. The 27-inch models feature user-accessible RAM slots and internal storage that can be replaced with modern NVMe SSDs, while both sizes benefit from serviceable power supplies, fans, and display assemblies.
These machines shipped with a range of storage options, from traditional spinning hard drives to Fusion Drives and pure SSDs. If your iMac still has the original HDD, you are almost certainly experiencing frustrating slowdowns that have nothing to do with the processor. A straightforward SSD upgrade transforms the experience entirely.
At RevivaTech, we have repaired and upgraded thousands of Intel iMacs. Whether you need a simple SSD upgrade, a complex GPU repair, or a full screen replacement, our Bournemouth workshop is equipped to handle it. We also serve customers across the UK with our insured postal repair service.

Common Intel iMac Problems We Fix
Recognise any of these symptoms? Book a free evaluation and we will diagnose the exact cause.
Extremely Slow Performance (HDD Bottleneck)
The number one complaint with Intel iMacs is painfully slow performance. In the vast majority of cases, the culprit is the original mechanical hard drive or a degrading Fusion Drive, not the CPU. Replacing the HDD with a modern SSD transforms the experience, making macOS boot in seconds and applications launch instantly. This is our most recommended upgrade for any Intel iMac.
GPU Failure (Especially 2015-2017 27")
The dedicated AMD Radeon GPUs in 2015-2017 27-inch iMacs are prone to failure due to thermal cycling and lead-free solder fatigue. Symptoms include screen artefacts, graphical glitches, kernel panics, and complete display failure. We perform BGA reball or full GPU chip replacement depending on the severity, paired with improved thermal paste to prevent recurrence.
Power Supply Failure
Internal power supply units in Intel iMacs can fail due to aged capacitors, power surges, or component wear. The iMac may refuse to power on, display a brief flash then shut down, or produce an audible whining noise from swollen capacitors. We replace the full PSU or repair individual components depending on the failure mode.
Overheating & Fan Noise
After several years, dust accumulation and dried thermal paste cause Intel iMacs to run hot, triggering constant full-speed fan operation. This accelerates component degradation and shortens the machine lifespan. Our thermal maintenance service includes complete dust removal, thermal paste renewal, and fan bearing replacement if needed.
Display Coating Delamination (Staingate)
Many Intel iMac models suffer from anti-reflective coating degradation, commonly known as Staingate. The display develops hazy patches, smears, or blotches that cannot be cleaned off. We can remove the damaged coating for a clear, usable display or replace the entire panel for a factory-fresh appearance.
Swollen Capacitors on Logic Board
Electrolytic capacitors on Intel iMac logic boards can swell or leak over time, causing instability, random shutdowns, and boot failures. This is particularly common in 2015-2017 models. Our technicians identify and replace affected capacitors using quality components rated for extended lifespan.
Fusion Drive Split or Failure
Apple Fusion Drive combines a small SSD cache with a mechanical HDD as a single logical volume. Over time, the volume can split into two separate drives, or the HDD component can fail while the SSD remains functional. We repair the Core Storage volume or replace the failing component while preserving your data.
Insufficient RAM for Modern macOS
Newer versions of macOS demand more memory than older Intel iMacs shipped with. The 27-inch models (2015-2020) support user-upgradeable RAM up to 128GB via a rear access door, making a RAM upgrade a cost-effective way to extend the useful life of the machine. Note that 21.5-inch models have soldered RAM and cannot be upgraded.

- xGPU BGA reball requires professional reflow equipment and temperature profiling
- xIncorrect SSD selection can result in incompatibility or lost data
- xDust trapped behind the display during reassembly is permanent without re-opening
- xThermal sensor disconnection can cause fans to run at full speed permanently

Intel iMac Repair & Upgrade FAQs
Common questions about Intel iMac repair and upgrade services
Is it worth upgrading my Intel iMac to an SSD?
Absolutely. An SSD upgrade is the single most impactful improvement you can make to an Intel iMac. Boot times drop dramatically, applications launch instantly, and general responsiveness improves beyond recognition. Most customers describe it as feeling like a brand-new machine. Contact us for a free quote tailored to your specific model.
Can you upgrade the RAM in my iMac?
It depends on the model. The iMac 27-inch (2015-2020) has a user-accessible RAM door on the back and supports up to 128GB of DDR4 RAM. We supply and install compatible modules with full testing. The iMac 21.5-inch has soldered RAM that cannot be upgraded. The iMac Pro uses ECC RAM that can be upgraded to 256GB.
How much does iMac GPU repair cost?
GPU repair pricing depends on whether a BGA reball or full chip replacement is required. Contact us for a free quote. This is significantly cheaper than a full logic board replacement typically quoted by Apple. We include thermal paste renewal and a 12-month warranty with every GPU repair.
My iMac is very slow but the CPU seems fine. What is wrong?
In almost every case, the answer is the original mechanical hard drive. Even iMacs with capable Intel processors become painfully slow when the HDD degrades. An SSD upgrade resolves this completely and transforms performance. We migrate all your data so you pick up right where you left off. Contact us for a free quote.
Can you fix the display coating issue (Staingate) on my iMac?
Yes. We offer two solutions for Staingate delamination: coating removal, which strips the damaged anti-reflective layer to leave a clear, usable display; or full panel replacement for a factory-fresh result. Coating removal is the more affordable option and does not affect display clarity for most users.
Which Intel iMac models do you repair?
We repair all Intel iMac models from 2015 to 2020, including the iMac 21.5-inch (4K and non-Retina), iMac 27-inch (5K Retina), and iMac Pro (2017). This covers a wide range of Intel processors from Broadwell through Ice Lake generations.
How do I get a quote for iMac Intel repair in Bournemouth?
Simply book a free evaluation through our website or contact us directly. We assess your iMac, diagnose the issue, and provide a transparent, no-obligation quote. Many repairs can begin on the same visit once you approve the quote.
Can you recover data from a failed iMac hard drive?
In most cases, yes. We have specialist tools for recovering data from failed mechanical hard drives, SSDs, and Fusion Drives. Even when the drive has mechanical damage, we can often retrieve critical files. Contact us for a free assessment and quote based on the complexity of your situation.
Do you repair the iMac Pro (2017)?
Yes. We service the iMac Pro including screen replacement, power supply repair, thermal maintenance, and ECC RAM upgrades. The iMac Pro uses a unique space grey chassis and Xeon processor, requiring specific parts that we maintain in stock.
Is my Intel iMac still supported by Apple?
Apple dropped macOS support for most Intel iMacs with macOS Sequoia (2024). However, many Intel iMacs can run macOS Sonoma or Ventura, which continue to receive security updates. Tools like OpenCore Legacy Patcher also enable newer macOS versions on unsupported hardware. Your iMac is far from obsolete, especially with an SSD upgrade.
Do you provide a warranty on Intel iMac repairs?
Every Intel iMac repair and upgrade comes with our comprehensive 12-month warranty covering both parts and labour. If the same issue recurs within 12 months, we re-repair it at no additional cost.
How do you remove the iMac screen for internal repairs?
Intel iMac 2012-2020 models use adhesive strips to hold the display in place. We use precision suction cups and a cutting wheel to safely separate the screen, then apply new OEM-grade adhesive strips during reassembly. Older models (pre-2012) use magnetic attachment. Both methods require careful handling to avoid display damage.
