Lenovo — ideapad 310 works very slow and hangs often

Address:

I bought a lenovo ideapad 310 laptop in november last year. It is supposedly a i5 processor laptop but is as slow as a tortoise. Slower than that actually. It keeps hanging very often.
It takes almost 6-7 mins to startup and then keeps hanging every 15 mins. Sometimes it doesnt even get on. There is a serious issue with the laptop and i request lenovo to address it.
