imac startup problems

[kammron]

twice in the last week, i turned my imac off
and the next day when i go to turn it on it wont boot.
the first time it got to the loading screen, would fully load, then do nothing.
the second time it went from the grey apple screen, to a blank blue screen, and again did nothing.
each time i was forced to reinstall os x as no other options fixed it.
no files or programs are gone, but i have only been puting it to sleep the last 2 days in fears it will do it again.
is this software related?
leopard coming the day its out, im wondering if a fresh os will fix it
