hi, i got this laptop. when it arrived it wont post, so i opened it and cleaned mainboard with ipa. after that pc power on normally, so i tryed to reassmbly all, but ofcourse after all was almost done, at a last try it wont post annymore.

so disassembled it again ad fount that almost all voltage are present, but when no post, northbridge and southbridge get hot very fast.

my question is what is cousing nb and sb getting so hot? at first i thought a vga problem, but can that cause those 2 chip get hot ?

any advice would be good.
