I have trouble booting the computer sometimes.

Hi, I have an HP Pavilion desktop almost 8 years old. Recently, I've been facing trouble switching it on. Sometimes, it just shows the HP logo with lines all over it. After many repeated attempts, it switched on and navigated to a page where it asked me whether I wanted to launch a startup repair (recommended) or start windows normally. I selected the first option, and it showed me another blue screen, that I've attached with this query. I just wanna know what's wrong, and how I can resolve it.
