Why Computers Crash? Improper Cleaning Procedures
There are a lot of hardware components that run together to make your PC work. Over time, these components can age and begin to work improperly. Unfortunately, these problems are hard to fix because they aren't always consistent. Moreover, the components inside that tower can overheat and begin to fail. If your RAM (random access memory) or Central Processing unit (CPU) gets too hot, they will fail and your computer will crash.
That is why there are fans built into each tower. These fans, though, can bring dust and other tiny particles into the tower and cause all the components to clog and eventually overheat. An easy solution for this is to take the casing off your tower and buy a can of compressed air. Don't blow into the hardware yourself, as you may spit a little or get dust in your face and sneeze all over your hardware. This could cause further problems with your computer. Use the compressed air from a distance so you don't do any damage, and please, do this outdoors. Keeping them clean is one quick way to solve the "Why do computers crash?" problem.
