AMD Radeon HD 7600M Series 2.7 GB Suddenly stopped responding problem

I'd upgrade to a better laptop NOW and rig the current HD up to the new one via adapter to transfer files over.

SATA to USB most likely.

Or if strapped, find a used replacement all-in-1 motherboard/CPU/GPU, but that could still be a better start on a new one.

Well as previous poster says may as well do it mate cos nothing is going to put that GPU right.

Just have to be aware Zena of what you are resting the machine on even your lap can be hazardous.

If you take my advice I would also think about that filter I mentioned over the air intake opening doesn't need to be fine but fine enough to catch the lint and heavier particulates. :)

HD 7670M, get that GPU replaced (depends on the laptop's motherboard)

Yep Roaster but mate that is going to cost more than a new machine at current shop rates out here at least - if you can find someone willing to do it??

A friend of mine suggested I should try "reflowing" the GPU. Basically, he used a hair dryer to heat up the GPU (?) No idea what he means.

Hmm sounds like you ought to rub it with leg of frog and snake oil

I have an idea that years ago when I was into building dedicated electronic stuff one could revive some of those old NAND gate IC's with similar methods but this is a totally different kettle of fish Zena.

I suppose you could shop around for another motherboard but you still have to strip the old one out and get it back in. The chances of getting a used motherboard that would nay good is fairly slim

Zena before you replaced the cooler system - the plate and heatpipe structure (cooler system) did you apply any new thermal compound? This is a material that "fills" the microscopic gaps between the chip and heatsink surfaces by conducting the heat through it from the chip surface and the heatsink surface where the two different surfaces mate together. I know they look smooth but in fact do not have a totally complete surface contact.
If not mate that is why the GPU is cooking and in hindsight now we know this it probably means that when you originally "cooked" the machines the thermal compound (it is a bit like form of grease for want of a better description) got so hot it in all probability flowed out of that contact point to a thickness that allowed those microscopic gaps between the GPU chip and the heatsink.
Now what you must do as soon as is to strip it down again remove the cooler system - clean the GPU and CPU chips (cores) and then the cooler plates using a good cleaning preparation and apply new compound to both surfaces chips and plates. I use a vinyl gloved finger to lightly spread the new compound over the entire surface and them on each chip place a small blob of thermal compound about the size of a half grain of rice.
Reattach the cooler system taking care not to over tighten the holding screws. When the machine starts up again the heat will "bleed" that small blob out over the chip surface. But you must take care not to put too much on to it will make a real mess.
Now cleaning I use the Arctic cleaning kit which you first clean any residue from the four surfaces (GPU & CPU & heatsinks) then "prime" it with the other solution then apply the compound and Arctic Silver will probably be the best to use.

Any problems please post back you just might be in luck. :)
