This is the telltale sound of one of your system fans going into overtime.
When you boot software that uses 3D graphics (or even when you boot up the computer!), you may hear what sounds like a small jet aircraft taking off within the PC. Colors will look strange, 3D models will stretch for no reason, “digital snow” will appear, or the entire screen will be covered in visual garbage. This is because the graphics card is how the PC “draws” onto the monitor. When something is going wrong with the graphics card, you may notice this via bizarre visuals onscreen.
