Okay, so last night I randomly decided to try it, and after about 30 seconds of being on, the operating system started to boot. Shocked, I continued on to see how everything ran. There indeed was a fresh OS on it, and everything was running fine. After about 30 minutes, however, the laptop randomly reset. The fan is rather loud and blows out very hot air. I tried to power it on this morning, and it took 30 seconds or so like the previous time. So, I have two assumptions, and if I could be given any guidance, that would be great:
It may be that the fan/cpu/gpu have not been properly cleaned and given new thermal paste, and so the laptop is forcefully shutting down because it is getting too hot.
If I am unfortunate, this heat has caused damage to the motherboard that is going to cause it to be permanent.
So, now my question is if there is any advice that would help point me in the right direction to find out which one of these it could be? I was planning on cleaning the fan and putting new thermal paste on today and seeing how well it ran. If this doesn't help, would that inform me that it is probably the motherboard that is wrong?
I'd rather not have a huge ordeal if I can just fix the laptop, and the seller said that he could refund me some money if I need to purchase a new piece, so that may be better than trying to get a refund and buying another one.
EDIT: I just cleaned the fan out and put new thermal paste on the processor, and the air is much cooler now. I powered on the laptop, but after a half hour, it froze this time instead of shutting off. Now that I booted it back up, it started checking file system on C: and says "the type of the file system is NTFS, One of your disks needs to be checked for consistency."
Any idea what this means?
DOUBLE EDIT: So the laptop has not overheated or frozen since that one incident. The only thing that is still happening is taking multiple attempts to post and the computer still seems rather slow and laggy for some reason. I'd usually assume the speed is related to the processor, and cleaning the heating and thermal paste would make it be able to function, but damage has already been done which is why it is somewhat slow. but I'm not sure. Can a professional please point me in the right direction so I can finally end this problem? Thank you so much in advance
