Acer India — Defective product sold by Acer

My system SNID- [protected]
I purchased Acer product and having hardware issues from beginning, I hardly used the unit and it always shows 100% utilization all the time with no program running, I got HDD replace twice in last 4 months and the issue was never resolved. I am afraid now that post my warranty will be expired, I will be end up paying my hard earn my to have these parts replaced in coming future as well.
NOW I WANT THIS UNIT TO BE REPLACED OR REFUND, NOTHING ELSE.
