Why does the laptop itself turn off and then turn on?

Question

laptops

I decided to change the RAM (DDR3) and replace the HDD with an SSD. I took out one die (2GB), put two (4GB each), took off the actual train and put the ssd. Everything worked, installed Windows, etc., but after a while the laptop itself began to reboot during operation and not turn on. Those. during operation, it turns off, tries to turn on, but cannot and only shows a black screen, although everything blinks, glows and spins. If you turn it off "forcibly" with the button, it will not turn on for the next few hours. And when it turns on, after a while the situation will repeat itself.

I tried to remove the battery and start it from the outlet, the situation is the same - it turns off and then does not turn on

. What could be the problem?

Answer 1

Perhaps the matter is in the RAM, you have DDR3, therefore it is best to check that the voltage is the same as on the old one. If you take more voltage with a voltage, then there can be disastrous consequences, up to the burning of the RAM and motherboard. Also, these signs are quite similar to overheating or a short circuit, or maybe all at once. You took it apart, double-check whether everything is screwed on, whether you have removed anything superfluous. Even Kapton tape, everything should be in its place.
