 Many people say that the BGA cold solder joint, re-welding can, in fact, is wrong. The chip itself, within the chip itself has a core, as well as a substrate, the core is welded on the substrate, the vast majority of the chip is a cold solder joint between the core and the substrate, then why do the side of the BGA can because the BGA when heated about 300 degrees, then also the core of the chip and substrate heating the core of the chip and substrate of an expansion and re-welded to know of them soldering tin ball is in microns calculated to the current technology can not be welded well. This is why the graphics re-heating it can be good, but bad reasons for a period of time. And then repair then bad. This graphics card has gone bad, you want another good video card, re-BGA up before. Only in this way your computer use to be stable. Repeated bad friends, should be your chip does not replace or change the chip is a beta version at the same time replaced the graphics card there are a few steps need to be addressed:

 Advisory QQ: 2359642263: directly in the graphics and the heat sink plus a thermal conductivity, good sheet metal, copper, and thermal silica films and the thermal grease, so that the graphics card heat sink close fit together, the first time heat dissipation;: Change the circuit of the fan, Fan not Turning notebook design, will be redirected when the CPU heat of his request, but ignore the heat of the graphics. So it is best to put the fan into a regular turn, increase the cooling air flow, reduce the internal heat of the notebook;: careful cleaning fluid to clean your heat sink; after 2006, NVIDIA Corporation products are heavily involved in after the notebook graphics discrete graphics notebook prices drop a lot of performance to improve a lot, at the same time bad and more and more. And bad are the NVIDIA chip welding motherboard from the G7300 to GO7400 went to these cards in 8400 and 9300, and 6150 and 6100 these integrated chips, because the heat is too big, you need the fan sustained high speed CPU and cooling of the graphics chip, but in use for some time, the accumulation of the fan outlet a lot of dust, if you do not clean the dust result is your computer's internal temperature is high, the fan speed to high heat can not out, at the same time will accelerate the aging of the internal components of your computer, over time your computer is hung up. Bad Nvidia chip, why is he bad? Because this highly integrated chip, the processing procedures and instructions a lot, so he will be enormous heat, overheating reasons, a lot of chips on the bad laptop Huaping is a very common fault, the cause of how different reasons arising from the failure phenomenon is different, the solution is also different. Chaotic the Huaping performance in text mode as a character, image messy one, the graphics card master chip cooling effect of adverse also have Huaping failure phenomenon. Approach: to improve the thermal performance of the graphics card. Second, the memory speed is too low when the memory speed is too low to match the speed that can not host, also have Huaping phenomenon. Approach: the replacement of high-speed memory, or reduce the speed of the host. Three memory corruption when the memory of the damage, at system startup will appear the Huaping chaotic character of the phenomenon. Approach: it is necessary to replace the memory chip. Note that some of the memory integrated graphics chip and graphics chip, so it must be replaced.
