Sorry...the thread is not very long, but in any event here are the instructions from the person who originally posted the fix on the other forum:
"First of all,sorry for reviving this very old thread and hi.
This is my experience..If you feel uncertain..dont do the steps i did
So my laptop slowly started to die on me while playing wow (yes i still play).
I got these red dots all over the screen and browned my pants. Shut the game down usually and was a bout to turn the computer off by normal procedure in windows xp.
During the logoff i got the blue screen of death telling me that nv4_disp something failed and then it started dumping some memory.At this point i browned my pants again and panicked and pressed the power button and pulled the battery.
After a good hour i inserted the battery and powered it on.Horror struck my eyes as i saw blue artifacts during POST and the same blue artifacts on the windows logo.
Computer wouldnt boot into windows, so i rebooted,pressed F8 for failsafe to remove drivers.Removed drivers and rebooted
Sure,the computer starts normally into windows,no artifacts in windows only.
I started to sweat like never before.Didnt know what to do.
Started scouring the web for solutions on my desktop computer.
I found this thread and thought could this be true. I even went as far as to bother the head of mxm-upgrade.com with my issues and asked if this is true.
Yes he said...One can re-flow the BGA which very little effort in fact.
And all this about a week or so ago.
Luckily i didnt sleep the past night so i scoured some more and found a few vids on youtube about how to re-flow just about anything with a BGA. So i gathered courage and dismantled my laptop and pulled the mxm card.
I didnt have the equipment as shown in the youtube vid so i pondered for a while and thought it should work in the oven as long as it gets hot enough.
Very well..aluminum foil would be easy as i ate a cheeseburger yesterday.
So i wrap the card in the foil and locate and expose ONLY!! the gpu core.
Heated oven to 75c at first.. 2 minutes at 75c
Cranked the heat to 100c and went outside with doggy ..so about 4-5 minutes
Came in and cranked heat to 150c ..approx 2 minutes
Even more heat at 180c ..approx 2 minutes
Final heat at 200c .. approx 3 minutes
I then left the foiled card in the oven at 75C for about 4 minutes before i took it out and left it on the table allowing cooling ~25 minutes.
Assembled the computer and what do you know..it worked.
Artifacts are gone,windows boots with drivers instead of giving me the dreaded white background.
I have yet to flex the card once again before i can make a final statement.
Nevertheless i see this as a temporary solution, not a final.
Just wanted to let someone know that for once in life i succeded at something on my own
Remember this is just me. If you feel uncertain then dont do this,in fact dont even think about it.
If you do try this method i take no responsibility if you burn your home to the ground."

Personally, I (Zdroj) shudder when I think of the oodles of $'s that were spent by so, so many on new video cards (and sometimes motherboards), when an all too easy workable fix was possible for many of them.
I hope some of you are brave enough to try this and report back with your results. This fix worked for me, and it is based upon sound principles. Good Luck!
