Whilst loading into game my client freezes, i have to restart my pc in order to load in

So this has just been happening recently the last week or so.

I can load and navigate the client fine but then randomly maybe after 6-7 games when i load into my next game my whole pc freezes (It dosent happen on other games)

i then have to completely restart my pc for my client to work again and by that time the game is remade and i get punished for it [slayer-jinx-unamused] I need to find a solution to this because it literally just happened and im being put on a 20 minute leaverbuster and im afraid that my pc will get me punished further through LeaverBuster
