Hard drive failure? Please help

Hi,

My computer has been recently rebooting at start up, if I get lucky like right now, I manage to get on.

After installing winamp a couple of days ago, my computer froze and the screen was bombarded with a "hard error" message. I quickly reformatted the hard drive but the installation had problems, and advised a disk check. I went through the process and reformatted again with no problems so I doubt it's a virus, but now my computer just loads to the start up screen and then reboots. After a couple of reboots, it says it cannot find the media disk or storage.

It could be anything, PSU, MOBO, CPU, RAM. But the reason I think it's my hard drive is because I would hear this clicking noise before it reboots.

Is my hard drive failing??
