I've been getting this the last few days. the hdd would make the click and the downward-whirl sound, like when i'm shutting down my pc. this is while the computer's on. when this happens, and i'm playing a game or something, the game freezes and crashes. is something wrong with my hdd? it's a western digital 200gb 7200 rpm ata. or maybe that particular psu molex isn't providing enough power? and this sometimes happens when i boot up too. it says please insert proper boot device. i have to ctrl alt delete and sometimes it goes into windows. yesterday morning i was trying to boot for 15 min, and it won't work. wtf???
