How to solve when the computer continuously turns on and off without displaying the screen

For the situation where the computer continuously restarts itself but does not display the screen. There are many reasons leading to this situation. It could be due to a virus, power source, loose RAM, overheating device, etc. Below are each case and specific solutions.

2/ High temperature

The reason why the computer does not display the screen when restarting is likely because the computer is too hot. Mainly because users have been using the device for too long a time, running many tasks at the same time. Therefore, the computer's thermal paste will dry out, leading to overheating of the chip. It could also be because the chip fan is no longer as it was and is not working properly. Therefore, the computer's temperature is pushed up, causing the power to shut down and start up continuously. Note, this is a severe and dangerous case because it affects both hardware and chip.

Therefore, you need to review and clean the computer fan. If you have experience, please disassemble the device, clean it and apply thermal paste to the chip. (If you are not knowledgeable, it is better to ask a qualified technician to avoid doing the wrong thing and leading to more serious damage). When your computer gets hot, give it time to 'rest', leave it in a cool place to cool down and then restart it.
