A few weeks ago, my computer started to submit crashes with the keyboard lights flashing. Initially I thought it was a problem with the Kernel, but installed the LTS version and the problem persists.
There is no exact time for the crash, sometimes occurs before the logon screen, sometimes after. When I start a game or a video.
I’m starting to think is hardware problem, is there anything I can do to check? I am a beginner on these matters.
Sorry for any errors of English, I am using an online translator.
