If your computer suddenly stops working and your system completely hangs then the most common thing to do is restart your computer. When you restart your computer many problems will correct themselves on boot. This is just an attempt and may not necessarily solve the problem that you are facing.



Check switches and connections



Many problems are caused due to lose cable connections and switches. Make sure all the cables connected to your monitor, keyboard, CPU, mouse, or other devices are tightly connected. It is good to ensure that proper power is supplied to all these connections. More importantly, ensure that all the switches to these are kept on before using them.



Programs not responding


The Windows programs might stop responding due to several factors such a lack of system resources, bugs in the system, or conflict of software or hardware resources between two programs. To solve this, a user can generally press the CTRL+ALT+DEL keys on the keyboard to close the program through the menu or the “Task Manager”.
