Hello Iâ€™am planning to upgrade my PC. The first time I bought a computer I got cheated by an assembler. Like, he never gave us the warranty cards. all the components were already there in the cpu . we wanted him to bring all the box packet components and assemble it right in front of us but he didnâ€™t. we never got the P3 sticker. When asked, he said that the sticker was not present in the intel box. After somedays use, the computer gave problems. The cpu made a humming sound. Even now it does. And the cdrom drive made a lot of noise whenever I put a cd in it. this time I donâ€™t want to get cheated. Will anyone please give me some tips on how to get what I pay for? This is a very common problem in India.
