Unfortunately something has gone wrong. It doesn't start at all, nor the monitor neither the power supply. I guess something on the main connector (12, 5 or -12) is shorted to ground leading powersupply to autoprotect. With the main connector disengaged PS starts; instead when i connect the mobo hd and fan don't start. Indeed isn't a big loss for me cause it was firmly stuck on simasi pattern: During latter times it hadn't been sounding, then overall conditions suddenly worsened, so before this recapping attempt i had no much hope.

That being said i would like to exclude evident and stupid mistakes with C8 and C9 positive and negative and their relation with main connector.

I suspect one of them the problem, i must have done an error. C9 positive seems well grounded but i'm unsure about the negative lead.

i 've also some concerns about C8 traces where do they connect? I wouldn't appear boring so if you could suggest a place to download schematics i would try a basic troubleshooting before i sell it for parts.
