The monitor works and after 10 or 20 minutes after starting the computer it enters standby mode. The monitor black screen goes out. The computer works but the mouse keyboard does not respond. This does not happen every time. The computer can be turned off only through the button on the power supply or through the button on the front panel by holding it for 10 seconds. What is the matter help. Will reinstalling windows help. Can I install windows crookedly?
