Laptop screen issues

[KC31]

 Hi

Can anyone assist as my computer is very slow to start and screen is showing this. It fades in and out with the colours on the screen. 

No liquid spills, although there were ants in my laptop a couple of days ago.... could that have caused major damage?? Is there anything i can do from here?

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 see that your experiencing issue with the Display:
Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

Did this happen after a recent window or software update?

I recommend you attempt to access the BIOS screen by tapping on F10 while the computer is restarting, 

If the issue persists in the BIOS screen which is outside windows, it would confirm a hardware failure, 
 

However, if it doesn't show up in the BIOS, it would confirm a software issue and we'll need to reinstall or update the display drivers using the Official HP Website: Click here
