Anyone else getting this error after PvP

Basically this happens during or after PvP. It says:
Driver unloaded without cancelling pending operations"
Then it starts to "dump physical memory"

My comp is old and internet is just high-speed, but this only happens during PvP.
I'm guessing it's Nexon's servers, the way they made PvP, my comp and internet connection.
Anyone know what this error means?
