Screen flickers at startup after eabling Hyper-V

Hi all,

I bought a new HP pavilion i7 pc and upgraded from windows home to windows pro.

When I enable Hyper-V, the screen flickers at startup only and I have to power off then power on then PC works with no issues.

This happens daily when I power on the device for the first time in the morning. I am sure it's related to Hyper-V because when I disable it, this stops happening.

Any suggestion what might be wrong as I need to use Hyper-V to work on Xamarin.

 

Can't Enable Hyper-V in Windows 10 Professional

Hi,



Thank you for writing to Microsoft Community Forums.



I appreciate your effort on this. As per my research the error code 0x800f0831 is generated when .Net Framework 3.5 is not enabled on the computer. I suggest you to try enabling .Net Framework 3.5 on the computer. Follow the steps mentioned below:

1. Press Windows key + R, to open
   Run dialog box.
   
2. Type appwiz.cpl and click on
   OK.
   
3. Click on Turn Windows features on or off.
   
4. Now, select the check box for .Net Framework 3.5 and click on
   OK.
   
5. Restart the computer.
   

You can also check if Virtualization feature is enabled in BIOS or not, if it is not enabled, I suggest you to enable it.

Enabling Hyper-V after it has been disabled?

Hi, I was doing Android development on my Surface Pro 3. Use of the android emulators required hyper-v being turned off, so I turned it off. Now, I'm working on a UWP app, and use of the emulators requires hyper-v. I have enabled hyper-v in the "Turn Windows
features on/off" tool, so it's enabled there, but it doesn't seem to be enabled elsewhere, possibly the BIOS. Problem is, there is no option in the SP3 BIOS to enable hyper-v. Windows tells me in two places (task manager, turn Win features on/off) that hyper-v
is enabled. However, running the following script in powershell:

tells me that it is disabled. Visual Studio also tells me it is disabled.

Any suggestions on how to fix?
