What does this mean? Is it a faulty ssd? Ram? That’s the only two conclusions I can come up with. Furthermore a lot of freeezes for minutes and in addition a weird boot(as soon as it boots it tells me my password is wrong and it’s a awkward screen that shows else but wrong password and a ok buttion)
