Lenovo
Hardware problem

Dear sir,

I had purchase a lenovo pc on diwali from "DEEPAK SALES 1st C ROAD SARDARPURA, JODHPUR"

Our cabinet make too much noise when we boot (start) the computer. But It should not make noise. Sir when we contact our dealer he just did nothing. he just said that this none of his matter. we should talk to lenovo service centre. They told us that they will send an engineer to solve this probelem

but they don't send any person to check this problem.

sir please guide us what we can do for this?
