I spent the past couple days working on a full recap of this A8N-SLI Premium v1.02. The board only had a few bad caps when I started, and it worked fine, but I figured I'd replace everything rather than have to repeatedly pull the board every time one goes bad.
I made a cheat sheet with locations and capacitor info, then ordered caps from DigiKey; everything Panasonic except for the 10uF caps, which are Nichicon.
When I finally got everything back together (Just the board, PSU, and PCI video card hooked to a monitor), the board wouldn't POST. The board gets power, but, when I push the power button, the CPU fan would spin, but then stop about half a second later. Pressing the power button again immediately after didn't have any effect. I tried again later, and several caps (specifically PCE1, PCE4, PCE10, and PCE9) exploded in sequence like firecrackers before I could flip the PSU power off. In addition, CE8 is now bulging.
I'm not entirely sure what I did wrong (aside from powering the board again). I used a desoldering gun to make easy work of the caps, and I made sure to install every cap in the correct orientation. Could I have damaged any components heating the board with either my iron or my desoldering gun? Did I buy the wrong replacement caps? What am I missing?
