Laptop screen flashes colors

Best way I can explain the flashes is that I get this pink/blue/reddish mess of a whole lot of colors on my screen. It literally happens in seconds and flashes, sometimes it recurs and other times it won't. Where the colors are also changes, sometimes about 40% of my screen flashes this mess of colors, other times less or it appears as lines. I have no idea what it is

However, if I could draw a similarity, it's sorta like the mess of colors you get on your screen if its broken/damaged. No shape or pattern, just a lot of colors. Though, my screen isn't broken or damaged (It's actually working fine as I type this, for instance) hence my loss of what it could be

I'd also like to add that this occurred specifically while I was playing an online game. Though in addition to that I'd also like to point out that a minor version of it appeared when I restarted my computer and it loaded into Windows

So I'm pretty lost as to what it is. Any ideas? Really hoping its nothing that will cripple my laptop completely -_-
