my personal experience
1- i got blue screen when boot the computer,..so the next day i send it to the back of the shop (like penjara wan) and they told me to get it next week + service charge... when argue,(cuz i just bought that mobo the other day), the guy talk to his supervisor, (i think) and quickly replace the mobo on the spot..reason=faulty mobo... lol

2- mobo prob. again.... got the replacement after 2 weeks...reason=MCP2 southbridge rosak (audio), USB 2.0...

3-keyboard ...samsung ps2 white colour...cheap wan, 15 ringgit... reason=defect item, (nescafe mark inside the keyboard), found when i open it...

4- corsair ddr ram- after 1 month rosak...
