hi everyone, i need your help!!!:redface: im not sure if im posting in the right forum, mods just feel free to move this wherever it's more apt... anyway, here's my problem... i installed the leopard 10.5.6 combo update the other night. everything worked well until last night when everything just hanged then i did a hard reset (powered out while holding the power button for a few seconds). after which, i went to sleep and didn't try to power on again until this morning. when i tried to turn it on, i just got a white screen. i tried another hard reset, and still nothing. so after searching the net, i tried the following first aid measures: 1. removed power cord, removed battery, pressed power button for 10 secs., reinstalled battery and power then restarted again. still nothing. 2. i used the installer CD and pressed D while starting up to check hard disk, nothing happened 3. used the installer CD and pressed C to try to reinstall software, CD was ejected and i got a blinking folder with a question mark. what does this mean??? no problem with files since i've got everything backed up in my external hard drive. i just can't make the @*$! thing work!!! please please help!
