dv9000 turns on and off intermittently, wont start at all [ Edited ]

[blisteredavalon]

Ok, today out of nowhere, everything on the screen of my pavillion dv9000 went screwy (repeated lines diagonally across the whole thing). Nothing was responding, or at least i couldnt see it responding, so i held the power button down to force shut it down. After that, whenever i tried to turn it back on, the lights, fan, and cd drive (or something else, sorry im not sure what it would be) came back on for a couple seconds, and then everything turned back off. Nothing come on the screen, not even the backlight. It then repeated this same thing every few seconds, even if i held down the power button, so i took the battery out to make it stop. One time it started booting up again (i did nothing different), but it only got past the first loading screen and then was blank for several minutes. I took the battery out, let it sit for half an hour, and i tried again. It still did the same thing but now the time that the lights, fan, drive are on is only about half a second. I've had the laptop for about 2 years and it has worked almost perfectly until today. Please help?

I placed this post in another thread, but it sounds like you have a damaged GPU.

I had this problem, but I have fixed it now. Fix below.

I have FIXED my misbehaving PC, and it is running better than ever!

I had the common problem that the GPU had overheated and had become unsoldered from the motherboard.

Here is how to fix it without spending hundreds of pounds/dollars!

Equipment/skills required...

*Small flat head electrical screwdriver

*Small Heat gun or jet lighter

*basic assembly knowledge of your laptop.

*know what a GPU is.

Firstly, strip the pc down to it's basic components, IE. screen, keyboard...

remove the motherboard and unscrew the heatsink from the board, leavint the CPU and GPU

exposed.

Remove the CPU from it's mount to prevent damage to it in the next step.

Surround  the GPU with kitchen foil, making sure not to cover it. (the foil dissipates heat and protects

the surrounding components)

now use a chef's style heat gun or jet lighter to heat up the GPU evenly, moving the flame in small circles, heating it up evenly. Spend about five minutes on this. (there is a covering of wax on the processor, don't worry about that...)

Remove the foil, but DO NOT throw it away! Fold a part of it up so it is approximately the same length and width as the chip on the GPU, but a little thicker. Put this folded foil onto the GPU to hold it there firmly when you put the heatsink back on. Place the heat sink and fan assembly back on the motherboard. If you cannot feel or see a pressure over the graphics processor unit, make the foil block a little thicker. make sure the foil is not touching any of the little capacitors or solder balls on the GPU. (you want to get lots of pressure with the foil. This will stop the graphics processor from coming loose again.

Put the entire pc back together and try it.

It worked well for me! 

Here's a link to the entire thread.

Hope this works for you!
