Windows 10: My Laptop brightness is malfunctioning.

Good day, My PC have working great but just 3 days ago when I turned on my PC to work and my PC started misbehaving.ISSUE: Whenever I am using my PC the brightness increases by itself, and the most annoying part is the brightness slider both on the window notification box and on my screen just keeps increasing the brightness. I have tried different solutions like antivirus scan, graphics card update, windows update, pc reset "keep my personal files" and total reset. I have tried all but nothing seems to solve this issue. My eyes hurts.SYSTEM INFO: HP 340 G1 windows 10
