i have a hp502n which i gave to my sis because she had some win95 cpu. well anyways for like 2 years ive been goin thro one problem thts a pain in the a$$. sometimes when i turn on the cpu the Hp screen comes up then it goes to a black screen with a white blinkin thing in the upper left hand corner. now its not the power suppy cause i changed it. i also do not think its the Hd cause its the second hd i had in it and its done it with both of them.. now if i kick the side of it, and restart it, it usually works. does any1 kno wht could be the prob?
Well, first off maybe you shouldnt be kicking it. My guess though is that the CPU fan is stuck and the thing is overheating. The kick in the side jars the fan enough to start it. I would pull it apart, dust it out and make sure the CPU fan spins when you start up the machine. ~Rich
