Is it possible to replace the graphic processor chip in a problematic card to make it work Instead of replacing the card itself.The card does not show any display in my dell XPS M1530?
Yes. This is something called BGA reball. You couldn't replace the card if you wanted, its attached to the motherboard. You can do it with a heatgun, a BGA stencil and solder balls. This is not how its professionally done, and is somewhat difficult and can damage other parts of the motherboard. Professional/industrial BGA mounting and reball is done with infrared heat and ovens. The chip itself is not bad. Its in fact the actual connection or "solder balls" that crack and go bad along with the underfill which is supposed to glue the chip to the board, but instead warps it. You could replace the chip with something that has the same pinout such as a g96 core, that would certainly be interesting to see what happens.
What is a Reflow Oven used for?
Reflow ovens are used to create circuit boards and other electronics. They are used mainly for reflow soldering for the surface mount type of electronic components.
What is the solution to a dull solder joint?
1) raising the maximum reflow temperature high enough to reflow the material thoroughly, 2) preventing vibration of assembly during and immediately after reflow, 3) accelerating the cool down rate after reflow , and 4) checking the alloy analysis for high levels of contaminants.
What does BGA stand for?
ball grid array

What does it mean if you're xbox360 screen keeps going fuzzy?
If the problem is exacerbated by heat then it's mostly likely that the BGA graphics chip is losing integrity. This can only be solved by a replacement motherboard, and should be covered under the warranty as long as you do not open the xbox's case. Try using it on a different screen just to make sure it's the xbox at fault.
