Lately, it's been quite difficult for me to start my XP.Whenever I start the PC it will say 'read error' and cannot be started.This will take several times of restarting until it finally burst into life to start XP.I've done a fresh install and all hardwares checked for any hang loose.And when the system is shut off it goes off with a loud clunk. I've done SMART checks and ckhdsk with F but not results of disk dying.Is this a sign of the disk going away ?? What should I do next ??
