A co-worker dropped off his PC to me to see if I could fix it. It's one of those HP Pavilions from BB (shivers). Anyways, when you turn it on, it doesn't go past that initial blue HP screen. It gives you options to press, ESC for Boot menu, F10 for (I don't remember), and F11 for system recovery. The PC won't allow it. Only when I hold down ESC or F10 while I turn on the PC does it show on the screen that it's been pressed but it just freezes. Nothing happens. I have made sure all the connections are secure. I'm stumped. Thanks in advance
