Computer screen repeat

[Heath4]

Hey, my HP laptop has been acting weird on startup. Upon turning on, the HP logo is displayed. Shortly after (5sec), it turns off as if it’s resetting! It keeps doing this for the past 2 or something years now; I just haven’t gotten the time for help due to work. 
If anyone could, please help me! 
Thank you!

Welcome to HP support community.

Step 1: Remove discs and devices

Before troubleshooting startup issues, remove or disconnect all discs and devices from the computer.

1. Turn off the computer.

2. Remove any discs and USB devices.

3. Remove memory cards from the card reader slot.

4. Disconnect all non-essential devices such as printers, scanners, external hard drives.

5. Leave only the mouse, keyboard, and monitor connected.

After you have removed all discs and devices, turn on the computer.

• If the computer starts, reconnect devices one at a time, to determine which disc or device is causing the problem. If the issue is solved, troubleshooting is complete.

• If the computer still does not start and exhibits the same problem, press and hold the Power button to turn off the computer. Do not connect anything, and then continue troubleshooting.

Step 2: Perform a hard reset

Many startup errors and other problems can be resolved by decreasing the amount of power stored in hardware components.

Decreasing stored power is sometimes referred to as a Hard Reset.

After you have completed these steps, if the computer startup issue is resolved, go to HP PCs - Updating Drivers and Software with Windows Update (Windows 10, 8, 7), and then go to HP PCs - Using HP Support Assistant (Windows) to update all device drivers.
