Thanks for your help guys, but now I am getting more serous problem. As I tried to reinstall XP, and when it starts to format c drive, it stops at 75% and make that scratching noise again and again.
I think it it is an hard disk problem or probably there are some bad sectors.
And at one time it showed "General Protection Fault" with "Trap 0000XX some numbers and something I have never seen before.
Maybe it is Hard disk.
