The laptop (Lenovo) is 10 years old, but it was working fine until the owner in a bout of anger hit it hard with their fist
After that it turns on with black screen, and then after 10-15 seconds starts loud fan noise.
I thought the problem might be that hard drive (no ssd) or RAM might have slipped off.
So I took them out and put back and the laptop turned on and worked for two days.
The third day, it turned on with black screen and loud fan noise again.
The laptop is not broken completely it seems, because after that I took out hard drive and RAM again and put them back.
It worked for 15 minutes and then turned off and again black screen and loud fan noise.
Could experienced members make an educated guess as to what might be the problem? Is it possible to fix it and how?
Edit: Lenovo laptop. It had both discrete and built in video cards (Intel graphics). But the discrete videocard has been fried long ago. I changed the thermopaste on CPU a month ago and then checked the tempretures and they seem ok, so overheating had not caused the problem.
I reinstalled the hard drive and this time made sure to press it hard to the contacts when fixing it with the screw, and after that it is working now for third day in a row. So the problem seems at least temporarily fixed.
