Black Flashes on Display while RAM Previewing

[Addy5EC9]

Hi Everyone. So recently I got a new Laptop. It's a Dell Vostro 5000 Series with a Core i5 7200U, Intel HD 620 Graphics & 256GB SSD. No dedicated graphics too. Everytime I start a new thing, whenever I preview something the display (whole screen) goes / flashes black and back in view. 

Can someone tell me whats wrong? I messed with the Texture Memory & turned on Mercury Transmit. Plus some thingsnin Mercury Playback Engine. Please help me I an a motion designer and I can't work like this.

Your new laptop was not a good choice for working with After Effects. Built-in Intel graphics do not have any of the required features for GPU acceleration. You can't expect anything to work if your system does not meet the After Effects System Requirements.

I used to use one with Intel HD 4000? 8GB RAM? And 128GB SSD? Isn't that worse?
