Issue in hardisk booting

[manav_blade]

I have build pc 2 3 MOnths back. But now there is a issue pc was working fine. Played many games also. But sometimes it shows insert boot media. But issue is this all. Hardisk are shown in bios. I thought I have corrupted hdd so bought new wd black 1 tb. It also worked fine but same. Issue came again sometime it done boot up with it..checked all cables also.

Did you check the cables or replace the cables? Try a BIOS update. Maybe try a different port.
