I purchased a new HP from Amazon. Yesterday I turned it on for the first time. Later I shut it down and then turned it back on t see how fast it shutdown and loaded. I got a blank screen and then the message "Press the ESC kep for startup menu" but the keyboard and mouse were frozen. I eventually unplugged the computer as there was no other way to do anything else. I tried again and got the same message. unplugged and tried again...this time it booted. Today, I turned it on only to get a blank screen (but the mouse cursor appeared). After hitting enter I got the same message "press the ESC ...." This time I tried control/alt/delete and it booted. turned it off and on again and this time it works. This should not happen on a brand new computer. What is the issue?
