League of Legends Not Opening – What Could Cause It

The so-called black screen you can get when opening League of Legends is very common. There are all kinds of issues that may cause it, such as:
- Various hardware problems
- Windows Defender
- Outdated drivers
- Corrupted files
- Lack of system resources
The last point is exciting because many people don’t think about it. League of Legends is definitely not one of the games that is known for its high system requirements. Nevertheless, it is important for people to check if their PC has what it takes to run it.
If you are not 100% sure what’s causing the issue, you can use troubleshooting. Try opening League of Legends as an administrator, checking the game’s social media to see if there is any ongoing issue, and more. Speaking of troubleshooting, let’s take a look at a few things.
Troubleshooting Steps That Can Help You Open League of Legends
If you are experiencing the League of Legends not opening problem, you can try a few fixes.
Close Other Apps and run as an Administrator
The first thing you should do if you are having problems with League of Legends is to try and close most other applications. Ideally, you should focus on the so-called “conflicting” apps but since you may not know which ones fall into this category, you should close those you do not need. The easiest way of doing that is to use your Task Manager.
As mentioned, you can also try to open the game by running it as an administrator. To do that, you can right-click on LoL’s icon and select “Run as an administrator”. Although this rarely works, it is possible to fix some of the issues.
Change Your Windows Firewall Settings
Windows Firewall can be very useful, but it can also cause a lot of problems. If you believe it may have an effect on how you play, you can change the settings:
- Go to Windows Security and choose Firewall and Network Protection.
- From there, choose the “Allow an app through firewall” and simply add Lol to it. This means that the firewall will no longer block LoL’s clients
