Going to need far more information than this. What are the components of your PC, the history of the problem, and a description of what you're doing when it happens? Cooler Master sells a number of components (case, PSU, cooling, various peripherals), not PCs. We only know things about your PC that you tell us and when you tell us nothing about your PC, then we don't know anything about it, which makes offering any kind of advice next to impossible.
