So I guess its a minor problem. No burns no nothing, i just need to have it cleaned thoroughly. I won't bother myself removing the board because it might ruin the CPU's attachment to the heatsink.
this is whre the smell is strongest, it was far more dusty so i had it cleaned with the brush, but the PC gives the same error and the smell starts when i turn it on. (Left it to dry for a day)
I found the alcohol soaked dust area (its brown, if it was burnt wouldn't it be black) that is the place where the smell is strongest. Its around a chip
