Hi everyone, and Merry Christmas! 
I bought recently hp 3420 aio pc, and i can't figure out how to solve a problem i have. When I start the computer, and boot the installation CD,(Ubuntu), it loads but then the screen goes crazy and starts blinking blue-green-red-white colors, each color blinking for a second or so. I saw on the boards here that it's a built-in screen test and that it can be stopped, but how?!?! It's making me mad, since I can't solve it!!
Have you had that problem, and if so, how did you solve it??
Thanks!
