Hello, is that happening only while playing video games? ^VA

Let’s run the hardware diagnostics to understand if there is any hardware failure in the system.
To do so:
1) Restart the system.
2) Keep tapping F12 key when the Dell logo appears during the startup.
3) Select diagnostics from the one-time boot menu and run the initial test.
4) Once done, do let me know if you receive any error code and validation code.

You can skip the extended memory test.

I'm having the same issue but when I'm screen recording things. Was it solved?
