CPU fan starts up randomly in the middle of the night and not able to turn on the computer

So ive had a Lenovo notebook G50-45 for about 2 years now. Over those 2 years, ive had little to no problems with it. 2 days ago at about 3 in the morning, while I was sleeping, the CPU fan starting blowing like a jet engine. I woke up from the noise and heard that it was coming from the computer. I lift the lid of the laptop, but the screen doesn't turn on. No amount of pressing the power button, moving the mouse, or pressing keys would turn the display on. So, i hold the power button to restart, and it restarts. When i logged in, everything seemed ok. No blasting CPU fan, display was on, and the computer was at normal speeds. I even ran a couple of virus scans. Nothing detected. This exact thing happens on the next night. That's when i came here. Any ideas on what the issue is an how i should fix it? Thank you!

Look in the event log to see what is going on at the time it starts up.

It's not happening at startup. I put the computer in sleep mode in the middle of the night
