Hi:

I have found that HP notebooks are very particular regarding what memory you install.

They love low density memory, and belch when you feed them anything else.

If you installed memory modules with 4 black memory chips on each side of the board and not 8, most likely that is the problem.

You want modules that look like this...

not this...

It also needs to be 1.5V, non-ECC, and unbuffered.
