What to do when your display flickers or goes black
By Tom Nonmacher
Welcome to another edition of our computer support blog! Today, we are looking at an issue that can be quite alarming when it happens: your computer screen flickering or going completely black. If you're facing such a problem, don't panic. There are several troubleshooting steps you can take to resolve this issue, and we're here to walk you through them.
The first step is to identify if the problem is with your monitor or the computer itself. If you have an extra monitor, connect it to your computer and see if the problem persists. If the new monitor works fine, the issue is likely with your old monitor. If the problem continues, the issue could be with your computer's hardware or software. It's also worth checking your monitor's power cable and video cable for any damage or loose connections.
Once you've determined the problem isn't with the monitor, the next step is to check your computer's graphics drivers. Outdated or corrupt drivers are a common cause of display issues. Visit the manufacturer's website and download the latest graphics drivers for your computer. If you're not sure which drivers to download, there's usually a 'detect my product' feature to guide you. After downloading, install the drivers and restart your computer to see if the problem has been resolved.
Sometimes, the flickering or black screen can be caused by running too many programs at once, causing your computer to overheat. If you notice your computer's fan running louder or faster than usual, this could be the case. Close unnecessary programs and let your computer cool down to see if this resolves the issue. Also, make sure your computer's vents aren't blocked and that there's sufficient airflow around your computer.
In some cases, the black or flickering screen could be a result of malware or virus. Running a full system scan with a reliable antivirus software can help identify and remove any malicious programs causing the problem. Remember to keep your antivirus software updated to ensure it can detect and protect against the latest threats.
If none of the above steps work, it might be a hardware issue. Faulty RAM, a failing hard drive, or a defective video card can all cause screen flickering or blackouts. In this case, it's best to consult with a professional technician who can diagnose and fix the problem.
We hope this guide has been helpful and that you're now better equipped to troubleshoot a flickering or black computer screen. Remember, while these issues can be frustrating, they're rarely irreparable, and with a little patience and guidance, you can get your computer back to normal in no time.
