Hi,
Recently my laptop has started malfunctioning. Windows does not boot! when I enter setup (bios) I can't see my HDD. Sometimes it's there and sometimes not. When the hdd is detected and run diagnose by pressing F2, it shows Hard drive is working fine. And sometimes when hdd is not detected it shows: run diagnose by press F2 and when I press it try to run diagnose it shows no HDD. I cant see my drive. Also I reset bios to default but still it wasn't showing. but after restarting 5 to 8 times it's started showing HDD and boot windows.

I would like to know that my Hard disk is faulty or the problem is with motherboard. and how to diagnose my laptop properly to find where exactly the problem is.
