freezes after start up since 11.04 upgrade

My laptop always freezes either at the login screen or shortly after. Their is no grub menu when loading up to choose recovery mode or previous install. What can I do?

I was able to find the grub menu and boot to recovery mode, I selected run in failsafe graphics mode and it froze again. It runs fine if I choose an older version, but the wifi isn't recognized.
