Hi everyone! I own an HP Pavilion dv5000 and it has been giving me some troubles these past weeks. At first it was a problem with it constantly rebooting after having displayed the good old Windows XP loading Black Screen. Today it started to behave strangely again, and I tried to control the situation. Since nothing happened and the OS was completely stopped and the screen had frozen, I rebooted it the old school (the very stupid way: you remove the batteries and the alimentation) When I tried to put it to work again, there's the black screen with the "HP Invent" thing and then nothing happens afterwards. I ran BIOS and I can't see the name of my HD anywhere, nor can I make the OS work in the "mode without mistakes", nor any option available when I press F5 right after the black screen appears. Can someone help me? I'd be very thankful, since my situation is a bit desperated. Oh, and excuse my english, I might have a few mistakes. Thanks everyone!
