Welcome to HP Forums, this is a great place to get support, find answers and tips, Thank you for posting your query, I'll be more than glad to help you out. I understand you are now getting a flickering screen on your HP Spectre notebook. I'll be really glad to help you with this,
To provide you with an accurate solution, I'll need a few more details:
Have you made any software or hardware changes on the PC?
Does the screen flickers even in the Bios?
Have you performed any troubleshooting steps before posting this on HP Forums?
In the meantime, let's try these steps here:
Perform a Hard reset on the Notebook
Check to see if Task Manager flickers:
Open Task Manager by pressing the Ctrl+Shift+Esc keys on the keyboard at the same time. If that doesn't work, right-click the Start button in the lower-left corner of your screen and then select Task Manager.
If Task Manager doesn't flicker, an app is probably causing the problem.
If Task Manager does flicker, a display driver is probably causing the problem.
In order to isolate the issue, I would recommend you to boot the computer into BIOS and check if the screen flicker, if the screen flickers as it's outside of windows, I would suggest this to be a hardware failure.
If the screen stays fine, then I would suggest you perform a Bios update as well as graphic card update, from the support website, using this link.
Please respond to this post with the result of your troubleshooting. I look forward to hearing from you.
