Don't know what happens to computer.when i start the computer blank screen appears for long time only cursor is blinking on the screen.After that bios setup appears and when i enter a bios setup no hard disk is detected by bios.Tried by restarting but same problem happened. After that I remove the case of computer and remove hard disk and star the computer bios screen appears quickly.Then I attach the hard disk again same problem black screen for long time and hard disk not detected.This problem happens again and again,changed hard disk two times,after some months same problem reappears.
