Help Im Desperate

**So, the deal is i have been playing league for a long time and never have i had this, when i'm in queue it will 80% of the time not show the accept button it will just continue the queue, at the end of the match i need to restart my client because nothing updates and it just says "you have disconnected" and gives me the option to exit instead (my ip doesn't update and cant even see the stats), i 80% have to invite m friends because i don't receive invites. So if anyone can relate and knows how to fix it please help me i'm desperate!**
