Answers :

Bud, i suggest you just buy a new MB cause lets say you fixed that MB and the PC/NB runs, that PC/NB will just run a maximum of 4 months without it blowing up again. and also it would damage all the internal parts of the PC/NB such as Processor, memory, and video card.

My Dell M991 TCO-99 monitor has lost the red colour i.e. there is NO red at all, an of course all the other colours are affected - shifted towards blue - is it the end of the CRT or can it be fixed by adjusting or replacing some component ?
