Competitive game problems

[SatanicUnicorn]

Sorry if this is not in the right place.
but
I was playing dirty bomb on competitive underground. In the middle of the game, I get kicked from it, I keep joining back but after a while the game just boots me from the server. It happened to me about 3 times. After I had joined that last time, the game completely crashed my PC. No, it’s not my pc, no it’s not my internet. I can run the game at 200FPS completely fine no problem. When I booted my computer up again then booted up DB, It locked me from competitive for 3 days.
