Hi Everyone- I was wondering if someone might be able to shed some light on a little problem I been having with an HP Pavilion Laptop. I'm so tired of calling HP phone support and having them run me through the same process over and over again only to have this problem repeat itself. Sometimes my laptop works well. However, there are many times where upon turning it on it will never boot to any screen at all. The screen will just remain black. Other times, the HP screen will come up but rather than proceed to the windows xp load screen the display will simply flash a blinking white cursor on a black screen. Finally, another thing I've also seen is that same blinking cursor with the message operating system not found sometimes flashing between cursor blinks. They (HP) have offered me the following solutions (All of which didn't solve the problem): 1.) Hold the power button for approximately 1 minute with nothing connected to laptop. (Not sure exactly what this accomplishes) 2.) Unscrew hard drive from bottom of laptop and then screw back in. I guess they called this proceduring re-seeding the hard drive. 3.) Run a check on the hard drive from the setup menu by hitting f10 I believe before the computer loads. The quick test ran fine. During the comprehensive test, the Laptop simply will shutoff everytime the test gets to 20 % complete. Can this be a hardware issue even though my laptop loads sucessfully sometimes? I just wish I didn't have this problem.
