i wanted to remove a fan grill (terribly limited airflow) so i shutdown my comp (first time in a few days) and i removed the front panel of my case, took the grill off, put the front panel back on and started up. started fine, opened msn, media player and FF2 and all of a sudden it crashed. so i turned it back on and it brought me to a page that said that windows couldn't startup. i tried starting in safemode, then i tried starting with the last known good configuration, thats when it said that it was missing a startup file (i forget the directory it gave me). next i opened up my case and checked all the cables and made sure they were plugged and i tried starting again, nothing. so the next time i went into bios and it showed the dvd drive on the IDE but it didnt show my hdd on the sata. i can also hear the hdd making a clicking sound. i also tried windows recovery and it gave me some stupid error.

this hdd has a history of crashing, this is #3.

any help would be very appreciated.
