I have a WD Caviar Green 500gb hd, my os is windows 7 64 bit. I have a 450watt SMPS and a microatx/ atx (NOT SURE) motherboard Gigabyte G41m-es2l. I work on my pc for continuous 6-7 hrs at a time. My usual activities are playing pc games, and doing office work. Two days ago while restarting my computer after a normal shutdown my computer started showing message " NO BOOT DISK FOUND REPLACE YOUR CURRENT DISK" (something like this). On checking my bios I found my HD was being detected normally by the bios.
On inserting the win7 disk for formatting I found that my HD partition table was destroyed and it showed 460gb raw … I created a new table , installed a fresh OS. Till now it is working fine.
My question is… What is the cause of this problem ???
or something else
Pls give me the right advice so i may be able to prevent the same problem from occurring again.
