Minecraft wiki entry for Crash, associated text: If the player is indeed experiencing crashing or visual corruption in other games as well, the first thing to check is whether their computer's vents are blocked, or clogged with dust (which inevitably occurs over time). Dust or vent/fan blockages can cause overheating, which may not be severe enough to cause problems during normal computer use, but during more intensive activities such as gaming, the temperature may spike. If the player is using a laptop, they should make sure any vents on its sides or bottom are neither blocked or filled with dust. For a desktop, the player should check obvious fan locations for blockages, and use a flashlight to peer inside the case. If there is much dust, or any internal fans appear to not be spinning, the player should either take their computer to a repair shop for a "tune-up" (mention that the player suspects there is overheating problems), or read a few tutorials online related to computer cleaning (note that a computer's internal components are highly sensitive to damage from ESD (Electrostatic Discharge, basically a static shock), so it would not be difficult for the player to accidentally damage their computer).
