Unfortunately, after installing win XP 32bit SP3 , my hard drive Running even when I'm not doing anything. it has period about 1 second . I mean each 1 second HDD's light turn on and I can hear a very little voice from HARD.I changed my hard drive , but didn’t effect. New one has the same problem.
I surfed on the net and found that many people have same problem, but there is no solution for it. I did all of suggestions like disable search index, disconnect DVDROM , and virus scan with up to dated NOD 32 (although it wasn’t necessary because I have installed windows only) but problem is still exist.
