Diagnosing a "dead" board

[Somerandomtechyboi]

Im gonna have a go at fixing this ep45 ud3p again, maybe it might not be the nb even though it looks like this

Spoiler

But if its even attempting to post then maybe i can have a go at attempting to fix this damn thing

 

Ive looked abit closer and i found some irregularities

 

Spoiler

On some capacitors theres some odd looking white stuff, i thought it might have been scratches so i just used a screwdriver and scratched at a cap but i couldnt recreate the white stuff and theres even a peak at the cap above the cap thats above the sata ports, so i think it might be leakage or something, do i need to swap these caps out? Cause theres about 10 of these but only 4 look that severe

 

The ram slots were surprisingly dirty upon closer inspection, one of the slots even had a ball of dust in it, no sht why it does c1 code

 

Spoiler

There also seems to be some exposed traces (the 2 long ones) though i dont think its an issue

 

 

ill continue to clean the ram slots tomorrow and see if itll finally posts, if it does then i guess ill get rid of my p5q

One thing I’ve seen done fixing handheld games and consoles is looking for blown fuses by testing continuity on them.  There’s a dude, I forget his name, who tends to title his YouTube videos with “[number] [item] can I fix it?”  Might be useful, might not. I haven’t seen him do PC motherboards.

Is it those glass tube thingys that you see inside psus? Looking abit more on the web they seem to come in glass tube form, mlcc look alike form, and 8 pin sop form, seems like i need to find something thats exploded or has a hole in it i guess??? But i dont really see anything blown up on this board and last time i tested it yeilded a c1 aka ram code so im suspecting that the ram slots are dirty which is true cause literally a ball of dust in one of the ram slots, maybe i shouldnt rely that much on isopropyl alcohol for fixing sht

 

If a fuse was blown then wouldnt the board be full dead or something?

The fuses look like little thick white candy bars a few mm in length with silvered ends.  They’re supposed to go from white to grey if they blow but it’s not reliable.
