I was playing a game that was asking my computer a bit more performances than usual, it overheated and turned off.
I turned it back on and it was super slow , I restarted it but it was even slower.
I opened it to clean the dust, saved my music , saved my photos and while doing this it crashed so I tried to restart it and it isn't booting anymore since then.
Do you think the overheating could have caused any phisical damages to the motherboard ore anything else ?
Can anyone help me with this quite anoying problem ?

Here's what it does:

And it stays on the "turned on but black" screen you can see at the end of the gif
