Most of time when I press the power button, after few seconds, black screen appears with the mouse pointer.
Hard Disk indicator flashes continuously, no changes and no error message on the screen.
Even no change, if I press Alt+Ctrl+Del. It remains same till the time I do not press Reset button or I do not restart.
When I press Reset button, only then it comes back with Windows Log in page.

I did ...
  • double check the hard disk cable connectivity,
  • clean boot and
  • even windows re-installation

but still the same problem.

Please help me to fix this issue.
