Pc crashing while playing

[ablabbouf]

Hi there.
I'm posting here cause i got some issue that is really really annoying and since i can't find where it is from i though maybe some of you could help me.
Ok so here's my problem : while i'm playing i'm gettin my keyboard frozen remembering the last order i gave him, i can do nothing with my keyboard but the game is still playing and i can for example cst spells with my mouse. that's the first part of it.
Sometimes it gets further by just crashing and freezing and i gotta reboot my pc.
And the worst part is when my pc just crashes and i get a blue screen saying me thi error : Windows_thread_exception_not_handled
This problem can come from many things and i checked most of them, but this problem is only occurong when i'm playing ( i didn't test other games ) but i tried to delete wow and reinstall it, without success.
So before formating the whole thing, which is very pissing me off since it's quiet an annoying thing to do, i wanted to know if someone could possibly find a solution.
Thanks for reading
