Ok, 3yrs ago I bought a HP dv9000. It came with XP but had many problems
with the power supply, memory and DVD drive. The 3rd or 4th time it went
back to the factory I got it replaced with a new dv9420us with vista64. It
also had problems from the get go. Well, my warranty finally ran out and the
prob. just got worse, BSOD on wake, BSOD when using the TV tuner, simply
shutting off suddenly. Went to Win7 rc1. Tuner still BSOD, just plain slow
and my anti-virus scans would simply shut off the whole power. Last night I
ran a virus scan from a Linux boot disk, same sudden loss of power. Then a
windows mem test, again, just died, like unplugged. So, I thought maybe
memory? Took out one mem chip and BOOM, Everything works!!!!

I don't think it's the chip but I will check today by swapping the one still
in there with the one taken out. Also, maybe having them checked at the
shop.

My question is this. Could this be a Vista/7 prob. or a design defect in
this model?
Is anyone else with the same dv9000 series having similar issues?
Is there a bios setting to salve this?

I would like to have my memory back, I'm down to 1G now.

Any help is appreciated, thanks.

Why not ? HP probably uses the cheapest components they can get.

Buy new memory.

This may not be what is wrong with your laptop, but something that you might
want to bear in mind..

The HP DV9000 was the subject of a recall (bad motherboard which lead to a
few faults developing over time) back in 2007 and, to that end, HP extended
the warranty by two years. It ran out Feb 2009.

My HP dv9000 has croaked twice, each time under extended warranty the
same thing MB went out. I get the lemon law the next time this thing
goes. I'll never buy HP again.

Anthony,
Either memory chip or memory socket.
One of them is bad for sure.
Other thing that comes to my mind is that both memory chips are not equal,
i.e., different manufacturer, different timings, etc.
That could also be causing issues by unproper detection in BIOS of memory
parameters.

Very good point since when Vista boots it checks the memory and if it all is
not running at the same speed it will not run.

Hi, Anthony.

I've told my sad story before, but in case you haven't heard it...

Last year, my home-built AMD X64 rig started having serious random problems.
The 4x1 GB OCZ DDR2 PC6400 sticks passed all the tests, but I still got
BSODs and other serious problems when I installed all 4 sticks. Two sticks
had been installed when I built the system; two identical sticks (all from
NewEgg; all the tiny numbers on the sticks matched) were added a year later.
My local shop was suspicious of one of the newer sticks, even though it
passed all tests, and suggested I run without it. After several months of
no problems with 3 GB, I contacted OCZ for an RMA. The OCZ tech insisted I
send back BOTH of the newest pair. He said that was necessary to be SURE I
got a matched pair. The two new sticks have performed flawlessly for about
10 months now. I was running Vista Ultimate x64 when the problem started
and gradually switched to Win7 during this period, starting with the
pre-beta a year ago.

Another MVP pointed out this article yesterday:
[url]http://blogs.zdnet.com/storage/?p=638&tag=nl.e539[/url]
" ...DIMM error rates are hundreds to thousands of times higher than
thought..."

Your problem may be in the mobo, as others have suggested. But sometimes,
even when memory passes all the tests, it still can have subtle flaws that
only a replacement can fix.
