Rajesh345, no offense mate, but your thread is in the wrong sub-forum. You should have created it in the
Service and RMA watch sub-forum.
Coming to your query, the RMA service for motherboards manufactured by Gigabyte, is handled by
Accel Frontline Limited. I suggest you call Gigabyte's customer service (motherboard helpline) number, which is 1800 425 4945, and enquire if there is a local service centre in your locality/area of residence. I believe the said number is toll free from a BSNL/MTNL landline.
I hope this helps.
