7800 GTX vmod - memory died?

I've voltage modded my GeForce 7800 GTX and the
memories got a lot of voltage, and something died.
I have been told, that I'd killed a voltage adjust
chip. If it might be my problem, I'd like to ask,
which chip should I check, or replace?

My other problem is, I unfortunetaly removed two
of the SMD capacitors from my VGA card. One of
them is the Q515, the other one is placed left
from the upper side of the C569 capacitor.

I have no warranty, that's why I try to solve it myself.

This is an Albatron GeForce 7800 GTX video card.
