Here is a small story of mine,
Over past few months ago, my computer keep on restarting and sometimes, shut down.My seniors, friends, myself have been reformatted it, but same problem still remain unsolved. Then I sent to the shop(ATT:This shop is notorious with bad computer service one!!!) where I had bought it, claiming for warranty. The technician said that it was not reformatted properly, then the shop charge me RM 30  for reformatting. However the same problem reoccurred again after 2 weeks. Then I sent it to a computer shop with good reputation for hardware troubleshooting. The result came out, the RAM is OK, but both mainboard and hard disk got error. After paying RM 10 for service charge, I sent my CPU back to the shop where I had bought the CPU, claiming warranty for second time.Then the technician said that it was because of not properly reformatted again.... " However, when I called to the shop, asking the shop to check properly, then the technician changed his statement, claiming that my mainboard got error and had been sent for warranty. Then I ask him whether my hard disk got problem or not. He said " Saya rasa hard disk tak ada masalah" translated ( I THINK your hard disk doesnt has any problem) He claimed that it might not has any problem without even checking it!!!! Then I requested has my hard disk checked. Then he told me my hard disk doesn't has any problem... I feel like the shop is not reliable. How should I do? Anyone can help me? Trouble shoot my hard disk myself??

will try it
