Need help - Hp Pavilion dv9000 CTO

Hi guys,

Recently i had some problems with my laptop - HP Pavilion dv9000 CTO.

Processor: Core 2 duo 2.0 Ghz
RAM - 2 GB DDR2
Graphic: Nvidia Geforce go 7600

Some weeks ago, i had win 7 ultimate installed and i was playing some pc games such as cod 4 and it kept getting stuck, so i closed it and my desktop was acting wierd with a pink dots all these funny colored patches all over screen, and it kept giving me this error "nvidia ... kernel recovered successfuly" it had become worse after a while where the screen kept shutting off to become total black and it was very frustrating so i decided to boot into safe mode where i saw pink dots all over screen, after maybe 1 hour it dissapeared. so i went back to normal use for a week.

After a week the screen kept shutting off and coming back on and system was freezing until a point where, when i shut the system down and turned it back on, all i can see is the backlight on, and all the blue startup lights on the keyboard is there, but cant see anything on screen.

I hooked it up to an external monitor, and i could see the screen but it had a lot of dots and lines on it so cant see clearly.

My laptop is no longer under warranty, i wanted some advice as how to fix it? maybe a cheap solution, i dont really want to send it to HP because it will cost a lot.

Thanks for the help.

 

A cheap solution?

There's thousands success stories around. If you have access to a heat gun, it would be more sophisticated but almost every apartment has an oven.

 

Thx for the reply will try this out soon!

 

Hey, i had a question i cant really find much stores here that sell thermal paste :\ Im living in Fiji Islands very far So i was wondering if copper flux can be used as an alternative? I mean Copper flux with a copper shim on top will reduce the temp?

 

Not recommended. You adding flux is essentially you are adding your heatsink without any thermal paste. The copper takes in heat so well that it could melt your chipset. There is a reason why people use thermal paste in materials other than copper. Thermal paste is designed to absorb heat away from the chipset and into the copper, thus heating the copper and not the chipset. Think of it as a unidirectional heat transfer buffer region between the chipset and the heatsink. Otherwise the copper will heatup as well as the chipset in both directions, essentially melting the chipset.

Try to find a ceramic or silver-based paste. Ceramic and Silver are staple substances that make up popular thermal pastes. I recommend ceramic in this case as pure silver-derived compounds can be very conductive and if misapplied could lead to short circuiting and a blow out. Ceramic isn't conductive so it is safer to apply.

Shims are fine to use as long as both side of the shim is applied with thermal paste. So one side is your chipset, you add thermal paste, then the shim, then more thermal paste on the other side of the shim then the heatsink.

 

Thanks for the info

 

From what those 4 links suggest, this is more for a desktop graphics card, since the gpu is integrated in the dv9000 CTO models, would it work putting the entire motherboard in the oven. I also have a dv9000 that crapped out about 3-4 months after the warranty ended and have looked at buying either a new computer or a new motherboard. Any help on if putting the entire motherboard in the oven would be appreciated.

 

Yep, the whole motherboard. I fixed my old dv9014 like that last summer since I didn't have access to a heat gun.

Remove all plastic stickers and covers first or they will melt or at least smell is really funny

 

Doing the whole motherboard on a dv9000 is a bit overkill.

Specifically treating the GPU itself is an option, but it requires very, very deft hands. I've seen it work with the help of a small butane torch, but I've also seen replacement instead.

 

The cooling to the graphics chip is poor in the DV series. You need to open it up and add cooper shims to the graphics and CPU. Then you need to add a thicker shim or a copper penny (before 1980) to cool the Northbridge. Use some Arctic Silver on the top and bottom of the shims and copper penny.

I recommend you do this if you are getting a new board or if you fix your current board. That's my temps with the mod suggested here.
