When the operating system is loading, the bar doesn’t finish loading and the screen stays blank or the computer restarts.

You can see small squares on the screen, or vertical lines, and sometimes nothing appears on the screen of your laptop. The LEDs light up, but nothing else happens.Ī graphics card failure is often verifiable at a glance. If this happens, it is possible that the graphics card can be saved, and you won’t need to change it.Īnother problem that can be caused by the graphics card (although it is not always caused by it) is that sometimes the computer turns on properly and other times the computer turns on but doesn’t show anything on the screen. First, you must detect the excess heat generated by the laptop, both in its ventilation and in the bottom of the computer (where the heatsinks are located).Īnother possible symptom of graphics card failure is that the image suddenly disappears or the computer randomly restarts when you test your graphics card by playing HD videos or games.

This process will be easier for a qualified technician. How to know if the origin of the problem is the graphics cardĪlthough it may seem that the symptoms are clear, these can be easily mistaken for motherboard or screen failures. If you own one of the following Mac models, it is possible that your computer will suffer a failure of the graphics card sooner or later: MacBook Pro 15” A1286, MacBook Pro 17″ A1297, MacBook Pro Retina 15” A1398, iMac 21,5” A1311, iMac 24” A1225 or iMac 27” A1312 or A1418. In addition, 2018 MacBook models with overheating are being reported, which is a sign of possible failures, which occur over their potential lifespan (despite Apple has said that it has been solved with an update). And also the 2012 MacBook Retina that had image failures, unexpected restarts and screens without signal due to the GPU’s chip for video transmission.Īnd, given that there is no infallible company, new models with manufacturing defects appeared in 20.

Leaving aside the older models, we still see many 2011 MacBook models, one of the Mac models that has had more graphics card failures. They had a failure related to the graphics card that those models were using at that time, NVIDIA 8600M GT, which contained defective chips.

Graphics card failure – Vertical lines on the screenĪpple has also made many errors in different computer models, such as the MacBook models A1226 and A1260 (20).
