problem with my hdd
 

when i turn my computer on i hear a sound coming from my casing and its coming from my HDD its sounds like my HDD restart itself nonstop, can someone help me solve my problem plz.

I think you need some diagnostic tools to check your disk.
There maybe have some bad blocks on the hard disk.

good luck.

do you still see the HD in the BIOS? is that working correctly?

prblem solve when i change another PSU yay:o

solved in the same month still:)
