so a common problem with a graphics card is when the GPU gets so hot that it starts peeling off from the card. You start getting colorful patterns on the screen when this happens. So we got an old 2900HD in our service center recently like that. We bought the guy a new card and i kept this one in hopes that i can fix it. So today i sat down with an electronics fan and heated up the chip, pushed it in a little and since our service center sucks we dont have a single working board to test it on. So when i got home i got so exited to test it that i didnt put on the heatsink in hopes that i can see the screen at least for a second to see if there are patterns or not. and to my surprize i did not see any (first time heating up a chip like that. but in less than one second the chip got so hot that it peeled off again and i started seeing even more patterns next time. So i was thinking. why dont they make the GPU chips on top side of the card instead of on the bottom? that way they wont peel off as easily hence gravity. I had an idea about this. Why dont i take off the heatsink again, turn the PC upside down and turn on the PC, that way while it heats up it will push itself back down, (maybe i can even push it with something) Anyone have any good experience doing this stuff, because i am a noob

I guess technically, they could put a metal strap or something over the chip to keep it from falling off instead of putting it on the other side... but... I think if the chip is falling off due to heat, that you may have more to worry about than keeping it on.

Also, it could very well could catch fire if it didn't fall off and continued to heat up. So it could be built that way to be safe. I'm not sure, though.

well the heatsink should technically keep it from peeling off.

wow... the first I've heard of this. I've heard of chips melting down or exploding, but... What's that chip made of anyways for it to be peeling off?

It's the solder - when the chip gets too hot it melts the solder, and if you are dead careful, it is possible to reflow the solder and fix it. It's basically the same problem that cause Xbox360's RROD.

Cheap cooling is often the cause, cheaper cards with nasty little fans on them will never last - go for the card with the most cooling hardware hanging off it. If the chip was held in place it would probably just burn out - it's when people quickly switch their PC off that saves it from the serious damage.

Really they need to find a viable alternativ to solder, if solder can't cope with working temperatures, then they need to use more sockets, like with processors - it's rare for a processor to have issues like this.
Too much cost cutting, not enough burn-in testing, and designing for speed rather than reliability are to blame. Personally, if I had a guarantee that a graphics card would still work in 3 years time, then I'd be prepared to spend more.

they wont use sockets the manufacturers wont make as much money off them, heating up the cheap will give you 50-50 chance that it will work again, i already did it but i was stupid and broke it again, but it still works i can try heating it up again, just if anyone have any tips how to not mess up next time?
