I am working on a Hp pavilion 6553 w/466 celron 128mb. At first i was have problems getting past the blue splash screen, but after a few try’s i can usually get in, Not the case anymore before when i was getting in to where you can select normal mode ,safe mode ,step by step stc.. i would recive and error 0258 previous boot incomplete? but the big problem now is when ever you connect the power cable the pc comes on and the power switch has no affect,and i’m not getting any kind of video signal. If anyone could please giude me i would forever be grateful. ps or iam i fighting a losing battle?
