PR: Mic stops working & flatlines PC

[Forrest Gump]

So as the title says my mic stops working and flatlines my pc....

Basically, I join PR:BF and it's all fine, using my mic like everyone else talking.... blah blah blah. Then out of nowhere my mic will stop working all together, for teamspeak, in recording devices, anything....

I can hear everything & everyone just fine but obviously not talk, I got to close PR and my pc runs like a shit, almost as if it's hardrives are completely full to the brim with virus and ect.
I go to shut down my pc but nothing happens it just says logging off for infinity, untill I hard reboot my pc.

I've never had this problem on PR before only since standalone(I think since standalone)
and it only ever happens on PR:BF NOTHING else.

The specs of my pc are very far from bad, and I'm sure all drivers are up to date.

If anyone can bloody help me with this I'd be very thankful.
