kernal panic. inconsistent behavior

i got first kernel panic error near end of may. restarted , seemed normal couple days. on may 30 got 3 kernel panic errors. after each of first 2 rebooted in safe mode, rebooted , computer operated few hours.

after last 1 wouldn't boot @ all. hear (the drives) start spinning , little light came on front, after few seconds (the drives) stop spinning, light go out. few seconds later process repeat. let continue few minutes before unplugging power , letting battery drain.

wife took in apple store checked out couple weeks later. said plugged in 1 of power adapters , booted on first try after few seconds of charging. end of troubleshooting..they told charge battery...

tried boot when came home, using 2 different power adapters (both less year old) had same results before taking in. use both power adapters on our other older macbook, no apparent side-effects. haven't had time take in again , try on theirs again.....

suggestions? can't give more info.. bought on year ago mac store in south korea. on bottom says 2009. it's solid bottom (meaning can't see battery). running snow leopard , updated, though can't remember if i'd done update recently.

 

this bad ram, failing hdd, or psu issue. take apple , insist on more thorough diagnostic test, giving them information can.

many potential parameters make guess here, run apple hardware test's come original media...might gather information apple:
