From all the posts above, you must be aware by now that you must at least reach a console/terminal before you can do anything: gain access to the boot log for troubleshooting or disabling/masking the suspected service from running, etc.
Try to get the terminal by:
1. Ctrl+Alt+F2. It depends on where the boot process stucks, one may or may not be able to switch to virtual terminal.
2. Boot into single user mode. Press 'e' in grub2 and append '1' at the end of the kernel boot option.
3. Use the liveCD/DVD to boot into rescue mode.
Perhaps we should take a step back. Can you tell us what did you last install that cause this problem? ATI/NVIDIA drivers perhaps? Or have you tried to boot using previous known good kernel version? You can choose which kernel version to boot into from Grub2 menu.
As you said, lets take a step back:
After I have installed Nvidia drivers, I have restarted a few times.
If I remember correctly, I have installed an update of Nvidia( something about Kernel
Also, the last software that I have installed was Virtualbox.
I will check again each of the posts, and will try everything...
If I will have to install a fresh Fedora, I have no problems
till now, this is the best distro i have seen...
