i ran chkdsk it asked me that it cant do it know because c is in use, it can do checking after restarting again. so i have restarted, it started checking. checking was in three steps, in the third step after completion of 75% , a msg displayed below that it is processed .. after this it was hanged up.. and then i restarted again, windows could not able to start it was asking me for installation disc.. that i m not having. so booting with system repair disc, i have restored my computer to an earlier date.. but how can i find that problem exists till now.. during when windows running.. !!!
