I installed Mountain Lion in my IMac and now, some times, when I start up my mac it looks with a black screen and white text. I'm really worry about it, can somebody help me?

iMac, OS X Mountain Lion (10.8.2)

    Don't worry, this is probably just Verbose Mode. It's perfectly harmless.  If you're not specifically invoking it, than it's probably down to an unwanted setting in NVRAM.  See this article on resetting NVRAM if it continues to bother you.

    i had a similar problem when i first installed ML. I had a black box filling the top left corner of of my macbook pro while loading it up. The problem was stored on my hard drive. i had a corrupt file or something. I had to create a bootable disk drive with ML on it and do a clean install and manually drag everything back from my Time Machine.
