When I opened the box, I was so exited!!! I followed the instructions precisely, and started the computer. Everything went well until I turned the PC off and attempted to restart it the following day. The PC would not restart/boot without disconnecting the printer and external hard drive first. The HP logo you see in the photo attachment is all that would display. So basically, I have to disconnect the printer and the external hard drive to get the PC to operate. I called tech support and they were no help at all!!!!!!! I stayed on the phone for nearly an hour and a half with the "SO CALLED" tech expert and he ended the call to go to lunch and never called back!!!!BUT I'M SENDING THIS DAMN PIECE OF CRAP BACK AND HE OR WHOEVER CAN DEAL WITH IT!!!!
