Hello everyone, I am not very tech savvy, so I apologise in advance for my uselessness.. I'm having serious issues with my Dell, every now and then the screen will fragment violently, sometimes just part of the screen, sometimes all of it, I can move the cursor and click and open things, if I can see the screen, which is not always possible.. I believe it may be a problem with my graphics card, my Dell does not have a tower, it is the monitor and tower in one device. It's getting to the point where I cannot submit schools tasks on time because of my system, and I am just in need of serious assistance.. Thank you.
