This morning I arose to find my computer screen displaying just my wallpaper, no icons. I hit ctrl,alt, delete; nothing on the screen. Having had this happen before, I knew that if I merely shut the computer down by holding the power button in and then turning it back on, it would start up fine. I then tried that. My screen displayed "no video input," and my keyboard showed no lights. The computer was on, chugging away, but nothing on the screen. I tried powering it down and then up again, several times. Nothing. Is it dead? (It's a Hewlett Packard Pavilion...a couple of years old.) Thanks in advance for any suggestions given.
