OS X starting in graphic mode only - no single user, no recovery

My intel-mac (2008, Yosemite 10.10.2) is suddenly only starting in graphic mode. No keyboard-commands during start-up are working - neither "r" for recovery-mode nor "alt" for chosing the startup-disk nor "s" for single-user-mode.

What may be wrong here? How can I fix it?

Thanks a lot!

Rainer

Perhaps you are not using the proper shortcuts:

In addition, I found out that in 3 of 4 boot-processes the booting comes to a halt with a white screen. Nothing happens, I can wait for a long time.

Now, I re-installed OS X Yosemite and the trouble seems to be gone.

What could have happened to cause this?

I'm not very frequently installing new software or removing software...
