My laptop has been freezing and when it does it starts buzzing

So I have this laptop that I got like 2 years ago and mostly didn’t have any problems until now. When I for example watch youtube or any other video streaming site, my laptop would randomly freeze, start making this weird buzzing/static noise and i would have to force shut it by holding the power button.Also couple seconds after it freezes the fan would kick in all the way. I recently updated from hdd to an ssd and at the same time from win7 to win10 and from that point onwards I noticed that it’s lot cooler(like when i put my and near the exhaust vent from the point that it’s almost unberable to not even being warm). If you have any ideas what is causing this problem i would be very thankfull to hear it.

Also sorry if my English is crap.
