i know my way around circuits, but im not expert, not even close lol. i have done 2 days worth of research just to figure out what info i have. (srry 4 the sh%tty pics. i had to use my fone bc my camera is broke.)this is a pic of the southbridge:
the burnt chip is in the red circle. after as much info as i could find, im pretty sure that its a 1.6a fuse (plz plz plz correct me if im wrong lol.) im pretty sure it looked like this:
has a symbol thats almost like an x, and says 16. now more or less, im wondering why my computer(atleast i believe) was still functioning fine. not really fine, the hdd crashed alot, even though it passed all tests(and tried other hdds with same resuls), and i couldnt get dvd, cd drives to work 95% of the time. and after trying three known working drives, i tore down the comp, and discovered the burnt fuse. but why was it still working? i mean i would imagine this would cause higher failure?? but regardless, what could have cause this? and above all, how can i fix it? im have been at this for days...... and even if u have very little info id still be grateful.
board is m077 southbridge set is ati.
one other VERY curious question if any1 wants to shed light on. in the first picture i have circled in black two ready spots to insert 2 more sata ports.
bottom side, open ones circled:
my eysight i terrible, but i think that there is only 4 connections to each port. r these usable?? (i do have that supplys, tools, and ability to insert ports btw). not nearly as important as the first question, but still very curious if i could uilize these. and if they werent usable, why run the lines at all?? w.e. thanks in advance.
