Why the computer crashes when the computer is hibernating
Q: I often have to think about it when I am doing graphics or programming, so I leave the computer. But sometimes thinking time is too long, and when you use a computer, it often causes a crash. Why is this?
A: For many users who like drawing, programming, pay attention to avoid sleeping in the process of program debugging. Status, because Windows starts screen protection and goes to sleep by detecting input signals (such as moving/clicking the mouse). In drawing and programming, the computer work is always very busy, but at this time, there is no need to input through the outside world. If the computer sleeps at this time, the data in the CPU and the memory will be in a state of "isolation". When waking up again, because the computer itself is awake through the software, it needs to occupy the CPU and memory resources, which often leads to memory data errors, resulting in blue screen or even crash. Therefore, it is necessary to save the disk as long as possible without using the computer for a long time, so as to avoid unnecessary losses.
