Ok guys, having trouble for the first time with my OS X not booting in. Everything was fine until this morning when i came into work, started up my Macbook as usual from sleep mode. was able to use OS X for a little while, had to leave to go onsite so i locked my screen (i use sizzle keys and made Command + L to lock my screen to the log on prompt). as soon as the cube spins to the logon screen, BOOM, all i see is the solid light blue screen just sit there. i walk away and 5 minutes later, it's still on there, can't recover or go back to my desktop, so i force shut down (hit the power button, and attempt to reboot the OS X. then thats when it all gets bad. Everytime i boot into OS X it just sits there with the blue screen and flickers back and forth with the gray gear wheel spinning and so forth. Ok, so next check, i go to boot into my Boot Camp partition into Vista. no problems, was able to boot in my boot camp partition without any problems (im typing this in boot camp at this moment.) so i dig around the net to try to find some help. So far i've been able to boot into my Boot Camp and the OS X Restore Disc without any problems. I booted into the OS X boot disc, and ran Disk Utility, ran the perrmissions check and the disk check and both fixed problems aparently on my OS X partition. went to boot back into OS X,.......blue screen. So now i do the PRAM and NVRAM reset doing Command+Option+P+R and again booted into OS X..........blue screen. Booted into Safe Mode (Safe Boot) took awhile, but again........stuck at blue screen and if i press any keys or move the mouse, the grey gear spins for like 10 seconds and just goes back to the blue screen. and the process goes over and over again. (later on this afternoon) I even ran FSCK to check the volume for problems. "it appears to be OK" ........... The good thing atleast in this situation is that i can access my OS X partition in Vista (via MacDrive) without any problems, so if having to reload my previous Time Machine backup (which stupid me forgot to back up my system over 60 days ago ) or having to just Archive my OS X and reinstall it, that will have to be my final choice. But i don't REALLY want to have to do this all over again if at all possiable. Any additional suggestions guys to trying to fix this problem? Thanks in advance.
