Usually these types of errors are too early in the boot process to get recorded to disk, but you can check /var/log/syslog or /var/log/kern.log to see if anything did get recorded there. Otherwise you should take a picture of the text on the screen next time this happens and post it here. Currently there just isn't enough information to work with.
