Parappana Agrahara is not listed as a SAI branch, because there is no branch. The walk-in is Ganesh Complex in Electronic City, above the TVS showroom and opposite Infosys.
A system that will not boot
When Windows will not start, or you want a fresh start, they can do a clean install. That is not the same as a new hard disk. A disk is replaced with an SSD or a new drive only when the disk is slow or failing. They still handle a cracked or black panel, a battery that will not charge, dead keys, heat, and a virus clean, and they keep those jobs apart.
Why a clean install is quoted on its own
You know whether the work is a system install or a part. The quote is given before any paid work.
