I had to restart my system when it hung while writing to CD using Adaptec 'Easy CD Creator'.

The system came up after hard reboot, but most applications fail to start. I've used Windows 'Safe Mode' to post this.

Except for Windows Explorer, Task Bar, and some applications running in the background (system tray), all other applications (Firefox, IE, Outlook, etc.,) fail to start -- even simple Windows commads such as command shell (cmd.exe), desktop properties or msconfig.msc fail to start. No errors are thrown.

Note: Task bar showed firefox process running, but the browser never popped up.

It seems like there's something wrong with explorer.exe.

There are few errors and warnings I captured in the event log (using Safe Mode, the event viewer wouldn't open in normal mode):
