Screen freezing issue.
 

I have just installed red hat 7.2, and when I turn on my laptop it asks me to choose which program to use. If I choose red hat immediately, everything is fine. If I dont choose the program within approx 15sec, the computer goes to some odd screen, and there is nothing I can do to get back to initial screen. I have to turn off, and on, to try again, quicker. Can I do something to prevent this from happening?

Also, all of my screen fonts are distorted. I tried to change font style, but all options seem to have same issue. What can I do to correct this?

Oh ya, one more. In my initial setup, I must have chosen wrong screen size. Thus, when I open a page, it does not properly fit the screen. Maybe this is why fonts are also distorted, hmm. How can I reconfigure to appropriate screen size?

Thank you,
