Do you have an iMac that’s turned on but has a grey screen? If you have an iMac with a grey screen, it’s likely due to a problem with the video card. The video card is responsible for storing information in memory and ensuring that information is quickly accessed on screen. When the video card isn’t functioning properly, the result is a grey screen. There are two main causes of this problem: a problem with the video card’s memory or overheating during boot.
If you suspect that your iMac’s grey screen is due to a problem with the video card, there are a few things you can do to try and troubleshoot the issue. First, check to see if there’s any visible damage to the video card itself. If there doesn’t appear to be any damage, try restarting your computer and seeing if the grey screen persists. If it does, it’s likely that you’re dealing with a faulty piece of hardware and will need to take your computer to an authorized repair center for further diagnosis.
Another possibility is that your iMac’s grey screen is being caused by overheating during boot. When your computer first turns on, all of its components are working hard to get up and running which can cause things like fans and processors to overheat temporarily. If this is what’s causing your grey screen, simply let your computer cool down for a few minutes before trying to use it again. In most cases, this should fix the problem without any further intervention needed. If not you need to have the new graphics card
