Hi, I'm kind of a noob, but I need some help to fix my pc... The thing is: my laptop cannot boot, when i start it powers up, lights and fans are on. Black screen, and after about 10 secs it dies and reboots. OS doesn't load. I know that the screen signal is ok. cause' SOMETIMES it boots perfectly fine, and there are NO problems until next boot. Can it be a loose connection with the BIOS? Or maybe it's caused by a fatal error during boot so the system restarts. I rarely reach the HP logo before it dies. sometimes i do though, but never further, either it's all the way from there or it's froen logo until it dies. hope you can help..
