I heard about fuses they can blow in the CPU, I don't know if this is possible on the GPU chip.
Don't know what tools you need to cleanly pull or plug a CPU/GPU. Anyone ever done this?

Hot-air rework stations are needed, and they're waaaay too expensive for everyone to get them. And stick the cpu about 1 mm too far, and you're screwed
If he wants he can try it of course, but I'm not going to do anything like that

Not just an hot air rework station, you would need a special adapter to be able to remove bga chips ( ball grid array, I think)
I have been using an hot air rework station for a few years now, for replacing TSOPS etc, this takes time to master, but as you have access to the legs on the chip it fairly easy, and any cheap rework station would do the job.
But the CPU is BGA like I mentioned above, and all the connections are under the chip itself, this makes them impossible to get to without specialist adaptors etc, and in my opinion, very hard to remove for the average joe blogs who only plays around with electronics as an hobby.
They are fitted by using tiny balls of solder, between the chip and the mainboard, which are both heated to a high enough temperature to melt the solder.

P.S The above info is from memory, so if im wrong in anyway, please correct me, so I can also learn like everyone else.

Actually, I heard that you can remove BGA packages by microwaving the PCB, so it heats up and the solder melts

Thanks for that extra bit of info m8, I just tried it, but the flames and sparks have just welded the microwave door shut, should I have removed the heatsink first ? (IMG:style_emoticons/default/uhh.gif)

Have a look at that, there they microwave a PocketPC mobo and take the CPU off

Great, I guess I did it wrong then (IMG:style_emoticons/default/smile.gif) ya could of told me that I had to use a combi oven.
I finally managed to get my board out of the microwave, and all seemed ok, but now I have to restart my microwave every 5 mins, it keeps displaying a blue screen of death, and telling me to contact my vendor (IMG:style_emoticons/default/smile.gif)

check your jumpers and your FSB multiplier.
Yeah and make sure that the BIOS is correct version for your owen and REMEMBER that there has to be enough RAM for it to fry anything ^^

You are quite correct. I use a DRS-24 for BGA re-work, (should say used, as I don't work there anymore).
