This PC arrived in the morning. Before I could make myself a lunch, I spent of my remaining morning and little afternoon on this PC. First it impressed me with its unique style. When I turn the power on it showed me some graphs, and the PC turned on; and then one minute later the screen turned dark, both keyboard input and mouse input were ignored. I then turned the power off and then on again. It showed me some life. After a long setup process, then it lost any interest in doing its job again. No response to keyboard/mouse input again. So I have to turn off the power, and then turned it on again. So we just played this kind of "game" for most of the morning and then I decided that I could not tolerate it any more....And call Amazon to RETURN IT!!!! It wasted my good three hours!!!
