GPU Repair

Hy, does anyone have some experience with repairing his graphic card ? It costcs 50€ and customer said that he has special machine to repair it with heat... I have 8600M Gt 512mb. How long that graphic work and what are temperatures ...
Ty...

 

It's hard to tell- re-flowing may enough to last you three months but may as well last for two years.
Does the company offer any kind of warranty?

 

No, actually this is not company but one guy is reflowing them and has no warranty but he said that he rapair 100 of them and they all works. but that could be only talkings. In my country i cant get one graphic witch would compare my computer, so i think that this is my only option ?

 

He probably is just baking your graphics card. You might want to save your money and try it yourself. A lot of users here have done it succesfully. But you need to keep in mind that baking/reflowing is a temporary solution. It might help for days, for months or even for years.

 

Well if you have no choice... It's slightly more expensive than I would expect but still probably quite a lot cheaper than a new card.

Anyway- it's a viable option and has worked for many people- the only thing you don't know is how long is it gonna work.

 

@pranktank: he said that he dont cook them, but he has some machine... he said even that he has about 4 hours work with it...
@downoads: yes that is what i'am scared of, how long is going to work..I have already cooked my graphic for 200C for 15 minutes and cool it down and after that it works, but for only 15 minutes. After that it didn't work no more. I couldn't even turned on computer anymore, but if i take graphic off the computer it starts without vdieo offcorse, but when computer was turned on with graphic it was very warm!

 

I actually don't see another way that he would repair a gpu with heat other than baking it. Maybe he has a better, more effective and precise technique... I don't know.

So if you pay him and it doesn't work he is not going to pay you back?


Edit: did you make sure your thermal paste was applied properly when you tried it after baking it yourself?

 

i didn't bake it with past on it ? becuze there was no past even before on it....

 

He probably does professional re-flowing not just baking therefore this is more likely to succeed. It's not the same thing.

Probably something like this

 

There was no thermal paste on your gpu when you took it out of your laptop?

 

seriusly no!

 

Cool, I didn't know something like that existed. Probably a lot more efficient than diy-ovenreflowing indeed.

 

I don't know what machine or anything else he is doing, i hope that he will repair my GPU for least 2years... what is wrong if i didn't have thermal past on gpu ?

 

Your gpu will overheat in minutes or even seconds. Your gpu's heat won't dissipate properly into the heatsink.

Ar you sure there was no thermal paste on the gpu? It's that grey/white stuff. And also no thermal pads on the gpu's memory?

Where did you buy this computer or gpu? Did you install the gpu yourself? Because a gpu without thermal paste won't work and get very very hot. This might be your problem. First make sure you have properly applied thermal paste and thermal pads.

 

Even rather old laptops need thermal paste right?

 

All laptops do need it.

 

This is strange. How could the gpu work before the problems without thermal paste?

 

Well it could and would work but at much higher temperature than it would with the thermal paste.
The smoother the radiator the better the contact thus the heat transfer even without the thermal paste.

 

How would you even get a laptop without thermal paste? Maybe applying some paste can solve the problem.

 

My mystake, there was paste, i saw some signs of it, but when i tryed to fix this GPU i give computer to my uncle witch has bake it, but looks like he forget to lubricate GPU, so computer work 1year without the past...on CPU it was, but i get new one 2 days ago... soo what would you recommended me about GPU? And yes temperature was really high... i have lubricate new past but still nothing...

 

So you now apllied thermal paste on your gpu and it didn't help?

Then I suggest you get it in for repair or buy a new one. The problem is that when you pay the reflow you can't know for how long it will work.

 

Agreed. Time to go to the repair shop now.

 

@pranktank: yes i lubricate pasta and still didn't work...
thanks you both for replays. i would like to know if my Acer Aspire 5920G is compatibile with GPU Geforce 8400M 256mb and if it's good ?
ok thanks for replys
