Blue screen Kernel Security Check Failure and Wifi Disconnect

[rowbyroh]

just received my new spectre x360 13t-aw200 CTO (9AJ99AV), but have repeatedly experienced two main issues in the first 48 hours:

1. randomly reboots (6 times) to blue screen error with the stop code "kernel security check failure"

2. wifi abruptly disconnects and i have to reset the network adaptor (almost every hour)

so far i have not done much on this machine other than troubleshooting and posting this question. here are the apps installed:

chrome

google drive

kindle

netflix

bamboo paper

drawboard pdf

krita

concept

hp pc hardware diagnostics (to check my wifi adaptor, which disconnects every time i run the test)

can anyone please help?

Thank you for posting on HP Support Community.
 

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

Firstly, perform Windows Update and HP Support Assistant: (do not skip any troubleshooting steps if you feel steps are repeating) 

To check for updates now, select the Start button, and then go to Settings  > Update & security  > Windows Update, and select Check for updates.

Install updates from HP Support Assistant: Go to Download HP Support Assistant to install the tool.

1. To open HP Support Assistant, double-click the HP Support Assistant icon .
2. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.
3. Click Check for updates and messages to scan for new updates.
4. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.
5. Click the update name for a description, version number, and file size.
6. Select the box next to any updates you want to install, and then click Download and install.

And, also run BIOS Update: Follow steps from the link: https://support.hp.com/in-en/document/c00042629
