Whenever I use my browser, the phone hangs up. How do I fix this?

[Parthiv Purkayastha]

Whenever I use my browser, the phone hangs up no matter whatever the browser. I have an inbuilt cm browser which I don't always use and disable it. I have tried other browsers like Chrome and Mozilla Firefox, etc. I have an MTV Slash Tablet with 8GB storage and 1GB RAM with Android KitKat 4.4.2. Please help. Thanks in advance.
