reballing consists of remove lead-free solders and add solders WITH a good amount of lead.
I do not know in USA, but here in Brazil there is no laws that prohibit the use of lead, reballing may not be effective in USA because the U.S. should be forbidden the use of lead. Probably there simply change bad solders with new bad solders (unleaded).
@SrRikintoshHacker It happend the solders that break are between the die and the substrate. Reballing will take care of the solders on the bottom of the BGA Chip, but the bumps inside might still break.
This is a problem with practically all the G84, G86 and perhaps some G92 chips. There was supposed to be a series of chips whose lot ends on #RF (eutectic bond and hitachi underfilling) , that will take care of this.
Well, on my Asus G1S, i reflowed did several times, but the solution was reballing lasted longer, but the damn died again after two years. Newer series of nvidia graphics for laptop also suck, my other Asus youngest nvidia GTX260 already died, luckily this video card is mxm, but the prices on ebay are not very inviting.
I bought an Acer 6920G with ATI video card, this is very fucking good, my laptop works almost 24/7 and keep going strong till this day!

Any heat shock in lead-free solder can damage it

Reflow is not the soluction.
The correct is the Reballing. Because the reflow is only a temporary repair...

@SrRikintoshHacker , perhaps you meant solution.
Reballing is a temp fix too. Practically all the G84 and G86 series is bad. (bad substrate).

@KJMailman Try and do a Reflow on your video chipset.
Mine is working fine since then :)
