so after one last attempt i took apart the heatsinks again, swabbed them up good with AS5, put everything perfectly back, slowly, and carefully
out of the case i go through burn process, everythings looking normal
i test it out after burn process, and i get a 0021 error, dvd drive not cooperating with the cpu chip?
doesnt make sense because
A) i dont even have a dvd or game in

reapplying thermal paste wouldnt make the dvd drive's firmware freak out
the other chance i heard was a cold soder on the south bridge, which in this case im screwed because i dont have access to any type of resodering tools
can anyone make anything of this?
