can a dusty pc cause motherboard spark on startup?

[JohnDoeVolvo]

so i had like maybe 60 tabs up with home depot and calculators up then my pc just shuts off......    no blue screen or anything just powered off immediately like someone pulled the cord..   then i went to check the breaker and it wasn't tripped so i went back inside and turned pc on and saw through the glass that the motherboard sparked (asrock x370 taichi) ....   what is the protocol steps to diagnose this... i was thinking psu is done but could it be possible its so dusty it caused a spark?

 

**edited to insert picture

 

 

also the spark was right at the blue rgb.. i have the lighting off   maybe it was just white light trying to turn on then turning off??

not unless there's something conductive on it. I'd be surprised if its still working after seeing a spark.

Procedure would be testing PSU by itself and the rest with another PSU.

Something conductive...In the dust. Something like metal filings or something like that. Have you sanded any metal around your computer in the last few months?

It's possible, but you'll need a lot of dust.  Was it worse than this one?

Sparks are usually very distinct. if it turns on an runs then you're good, but you haven't mentioned if you've tried turning it on since then and if so what happened.
