Since then my computer would just stuck on the grey screen with the Apple logo every time I tried to reboot it. Some useful log appeared when I tried to boot it in Safe Mode and single user mode: disk0s2: I/O error. 0 [Level 3] [ReadUID 0] [Facility com.apple.system.fs] [ErrType IO] [ErrNo errno 5 input/output error python 5] [IOType Read] [PBlkNum 24] [LBlkNum 2][FSLogMsgID 327376684] [FSLogMsgOrder First] 0 [Level 3] [ReadUID 0] [Facility com.apple.system.fs] [DevNode root_device] [MountPt /] [FSLogMsgID 327376684] [FSLogMsgOrder Last] 0 [Level 3] [ReadUID 0] [Facility com.apple.system.fs] [ErrType IO] [ErrNo 5] [IOType Read] [PBlkNum 55232] [LBlkNum 763][FSLogMsgID 375551380] [FSLogMsgOrder First] 0 [Level 3] [ReadUID 0] [Facility com.apple.system.fs] [DevNode root_device] [MountPt /] [FSLogMsgID 375551380] [FSLogMsgOrder Last] 0 [Level 3] [ReadUID 0] [Facility com.apple.system.fs] [ErrType IO] [ErrNo 5] [IOType Read] [PBlkNum 55008] [LBlkNum 749][FSLogMsgID 299898203] [FSLogMsgOrder First] 0 [Level 3] [ReadUID 0] [Facility com.apple.system.fs] [DevNode root_device] [MountPt /] [FSLogMsgID 299898203] [FSLogMsgOrder Last] That was when the booting process got stuck. The log seemed to suggest that there were problems with the disk i/o and mounting the file system. To you experts: Can you interpret what this means? Was this a hardware problem?

(Neither Normal nor Safe mode). http://superuser.com/questions/486048/repair-or-recover-drive-from-mac-osx-recovery-mode Single User seems to work. I can only boot from Recovery Mode or DVD. The scenario was the following: Computer was asleep (lid down). Lifted the lid then connected USB mouse. Mouse nor trackpad nor keyboard responded. Closed the lid, removed the USB mouse then opened the lid again. Trackpad and keyboard responsive once again, but after trying to close some programs computer freezes.
