Actually my technician told me that there is some problem with my hard disk, the plotter is making some noise (though very dim). According to him, on hibernation the plotter stops rotating with a great deceleration but on shutting down it stops with proper deceleration.
Hence, excessive hibernation has somewhat jammed my plotter with the thing which stops it. And because of this reason my SMPS is unable to take the load of my HDD.
For about 3 weeks now I've been rebooting my computer twice every time after removing the SMPS wire from the HDD and then reconnecting it and switching it on. If the computer has been switched off for long and I try to switch it on normally, the system goes off even before the booting beep.
Am I clear ?
