crash while in game

when i play rift or tft my game will crash and give some error message not bugsplat. game will shut down and i go back to client and reconnet. after i reconnect no more crashing or ping spikes. this has been happening for about 3 days now and it is getting tiresome. i checked my net and and all my different settings. tried some of the hotfixes and nothing is wrong with pc. this is a client issue since that mini patch they did i believe. please rito fix this damned thing im tired of having my games ruined.
