My parents finally have DSL.

Then I realized that there is something seriously wrong with my parents' PC. The machine freezes ramdomly and everything is disabled. I have to use the power switch ever 5 to 10 minutes. My dad said that the PC had been repaired a few months ago and both the mainboard and CPU had been changed.

It is obvious that the damn dealer gave them a used and apparently broken mainboard and that is causing the ramdome crash of system.
