Chosen Solution

I have an Acer Aspire V3-571G. Since a year ago, It could not boot up from Sleep mode (repeatedly restart) unless I change RAM’s slot. Then I disabled Sleep option and used Hibernate, but now it can not boot up from Hibernate and Shutdown also. Recently I have changed its keyboard. current situation: it can not boot even after shutdown, but if I change RAM slot (2 * 4GB), it boots successfully. I tried to boot it with just a SSD drive and RAMs (Keyboard, Touchpad, Wifi removed) and failed. I also changed RAM with no success. I have full access to my laptop and seeks repair options. Can anyone help?

Although the Sleep and Hibernate options are configurable in the Settings app, a computer that cannot boot up from Shutdown cannot boot up at all. I’m not sure if you are saying that your computer is functioning poorly, or that it’s completely “dead” and won’t turn on. Please help me understand - what tasks are you trying to accomplish with your computer, and what exactly is the computer doing that is blocking you from finishing your work?
