My iMac (17" 800 mhz) has been crashing a lot recently. yesterday i got two kernel panics, one was the gray one with the text in different languages telling em to restart, the other was the weird one with the text along the left side of the screen. It's crashed probaby about 10 or so times ive had it (about once a month). Don't get me wrong, i haven't looked back once since switching last august, and i don't think i'll ever switch back. It's just that i hear everyone talking about how their mac hasn't crashed in 6 months, and i wanna say that too. what can i do to fix this, i'm not doing really intensive stuff, i don't see why the system should be failing. i repaired permissions last night, and its been fine since. i've only done fsck -y once (even though i don't really know what it does), and that was a few months ago. should i try fsck -y again, and if so, how often should i do this. is there any other regular maintainence that i should be doing to keep it running smoothly. I use macjanitor every now and then, not sure if that helps at all.thanks in advance.
