Hello, I am using iMac early 2008 and I have been facing this issue a lot recently. My computer won’t start and after it does it won’t take me to password page however, it would start and function normally after a couple of restarts. But today it isn’t working, this issue has been happening for almost 2 months week after week. What can be the solution to this? Any common problems that can cause this?? I have attached a photo of it
