Fix 1: Close background programs

Usually we’d turn off unnecessary programs when we play games on PC for smoother performance. Same for Nox Player, it’s the best to run this emulator without background programs eating all the resources or causing interference. You can close the background programs completely in the Task Manager:

1. PressCtrl andShift andEsc to open the Task Manager.
2. Under theProcesses tab, select the process(es) that you want to shut down, and clickEnd task .

If this doesn’t solve your problem, try the next fix.

Fix 2: Enable virtualization

Virtualization technology allows multiple operating systems to run on one physical PC. Since we’re trying to run an Android emulator on a Windows PC, it’s essential to enable virtualization which could improve the performance of Nox Player.

First you can check if virtualization is already enabled on your PC. If not, you’ll need to enable it in BIOS.

Check if virtualization is turned on

1. Run Nox Player. On the top-right corner, click thethree-line icon and selectSystem info .
2. Look forCPU VT . If it’s already on, you can jump tofix 3 . If not, you’ll need to enter BIOS to enable it.
   

Enable virtualization in BIOS

1. ClickStart >>Power . Hold down theshift key and clickRestart at the same time. This will completely shut down your PC before it reboots.
   
2. When your PC restarts and shows the manufacturer logo,hold down the BIOS hotkey until you enter BIOS setup.
   The hotkey is usuallyF1, F2, F12, Del or Esc depending on different models. If you’re not sure which one works on your PC, consult the manufacturer manual or search online.
3. Find the virtualization setting in BIOS. The layout can also differ on motherboards, so you may see different terms. Look forVirtual, Virtualization, VT-X, or SVM .
4. Enable virtualization, thensave and exit .

NOTE: Sometimes even if you have virtualization enabled, Nox Player would still crash. One extra step you can do is to turn off Hyper-V, which is a Windows feature that may cause interference when virtualization is enabled.

Disable Hyper-V

1. Press theWindows logo key andR to invoke the Run box.
2. Typeappwiz.cpl , then clickOK .
   
3. On the left panel, clickTurn Windows features on or off .
4. Untick the boxes of Hyper-V related settings , then clickOK .

If you’ve enabled virtualization but Nox Player still crashes, try the next fix.

Fix 3: Check your security software

If your firewall and antivirus software (if you use any) have blocked Nox Player, it won’t run properly on your PC. You can add Nox Player to the whitelist, and configure your antivirus to stop the interference.

Allow Nox Player through the firewall

Check if your firewall is blocking Nox Player

1. Press theWindows logo key andR to invoke the Run box.
2. Typecontrol panel , then clickOK .
3. Switch toView by: small icons , then clickWindows Defender Firewall .
4. ClickAllow an app or feature through Windows Defender Firewall .
   
5. Scroll down to see if Nox Player is already on the exception list. If so, jump toantivirus configuration . If not, follow the steps below to unblock Nox Player.

Add Nox Player to the exception list

1. ClickChange settings , then clickAllow another app .
   
2. ClickBrowse . Glary Utilities PRO - Premium all-in-one utility to clean, speed up, maintain and protect your PC
3. Navigate to where you installed Nox Player and addNox.exe .
4. ClickAdd .
5. Tick the checkbox of Private network . This will ensure Nox Player is only unblocked when you’re using a private network, such as home Wi-Fi, out of safety concerns. Or you can allow Nox Player through all types of networks if needed.
   
6. ClickOK to save the changes.

You can test if the crashing issue returns. If it persists and you’re not using any antivirus tools, jump tofix 4 . If you have installed antivirus on your PC, follow the steps below.

Configure your antivirus software

For antivirus, you also need to make sure it’s not blocking Nox. You canadd Nox Player to the whitelist and then test the issue again.

In addition, many antivirus software requires hardware-assisted virtualization for additional protection. As we mentioned above, virtualization is also essential for Nox Player. When both programs run at the same time, they may conflict with each other. In this case, you’ll need toturn off hardware-assisted virtualization for your antivirus .

Below is a list of tutorials to configure settings for a few popular antivirus tools:

• Avast
• AVG
• Kaspersky
• Norton
• ESET NOD
• McAfee

You can disable your antivirus temporarily if you want to test if the antivirus software itself is causing the interference,. Be extra cautious since browsing the web when your PC isn’t under protection can be risky.

If your antivirus program does seem to cause the problem, contact the supplier for further assistance.

Many programs such as Twitch and Zoom have an overlay feature, which is quite handy. However, overlays could cause performance issues for other programs, including emulators and games. If your Nox Player keeps crashing while you have overlays turned on, make sure to disable them and test the issue.

If this doesn’t solve your problem, move on to the next fix.

Fix 5: Update your graphics driver

An outdated or faulty graphics driver can cause game performance issues and affect emulators. You may want to make sure yours is up-to-date and functioning properly.

There are two ways to keep your graphics card driver up-to-date. One is to manually update itvia Device Manager . If Windows doesn’t have the latest version available, you can search on the manufacturer’s website. Be sure to choose only the driver that is compatible with your Windows version.

• INTEL
• AMD
• Asus

Fix 6: Increase virtual memory size on your PC

Insufficient virtual memory (paging file) size can be a reason that Nox Player keeps crashing. Increasing virtual memory on your PC may help with the problem, so you can configure as needed. Here’s how:

Check the paging file size on your PC

1. Press theWindow key andR to invoke the Run box.
2. Type insysdm.cpl and clickOK .
   
3. Go to theAdvanced tab. Under the Performance option, clickSettings . WinUtilities Pro
4. Switch to theAdvance d tab and clickChange . Jutoh is an ebook creator for Epub, Kindle and more. It’s fast, runs on Windows, Mac, and Linux, comes with a cover design editor, and allows book variations to be created with alternate text, style sheets and cover designs.
5. You’ll see your virtual memory (paging file) size.
   

If you want to increase the virtual memory size to fix the Nox crashing issue, you can manually allocate the paging file size:

1. Untick the checkbox ofAutomatically manage paging file size for all drives , then selectCustom size . It’s suggested to set your paging file size between 1.5 times and 3 times your RAM.
2. If you don’t know how much RAM you have, first, press theWindows key andR to invoke the Run box. Then, type inmsinfo32 and hitOK .
3. In the pop-up window, look forInstalled Physical Memory (RAM) .
4. Once you know how much RAM you have, use the following formula to calculate the values you should fill in:

1GB = 1024 MB
Initial size (MB) = 1.5 * the amount of RAM (GB) on your PC
Maximum size (MB) = 3 * the amount of RAM (GB) on your PC
5. For example, I have 8 GB RAM, so I should set the initial size as 8*1024*1.5=12,288 MB, and my maximum size would be 8*1024*3=24576 MB. ClickSet andOK to save the changes.

Fix 7: Change Nox Player settings

If you’ve tried the fixes above but nothing worked, consider adjusting the settings of Nox Player. You may have to sacrifice a little graphics quality, but it should help improve the stability of the emulator and hopefully stop it from crashing. Here’s how:

1. Launch Nox Player. Click thegear icon on the top-right corner to open system settings.
   
2. In thePerformance settings , you can try switching between thegraphics rendering modes to see which brings better performance. Alsolower the resolution .
   
3. UnderGame settings ,lower your FPS . You can tweak around to see what FPS value can best balance stability and performance, but we don’t recommend going below 40 as the graphics quality might suffer.
   
4. Save the changes and restart Nox Player.

If this doesn’t fix your problem, we have one more fix you can try.

Fix 8: Update/reinstall Nox Player

One last thing you can try is to update the Nox Player or reinstall the whole program. Using the new versions can fix known bugs and will likely reduce crashes. By clicking thethree-line icon on the top-right corner, you’ll be able tocheck for update .

To do a clean reinstall, make sure you delete the Nox Player as well as all the local files and cache before you reinstall the app.
