every time i start my computer I get a black screen that says hit F1 or F2 and I have to hit F1 to go to main screen or F2 to computer set up and I can't get it to stop.  I don't know what to do to get it to stop. 

On another note, I also get a blue screen, not very often that says it is going to begin pyisical dump of memory.  What the heck is that and why and I getting this.  My computer is only a year old?
