No, i wanted to get more RAM for that computer. So i turned it off, took the old stick out to read the label and check what i needed to buy, put it back in, turned it on....dead RAM.
I suppose it's possible that something else happened. Maybe got some dust or something inside the case when i had it open and shorted some connections on the mobo or something, but i think it's most likely that i zapped the RAM when i touched it.
As a side note, i always used to touch a metal part of the case to ground myself before touching any components, but i'v since realised that none of the metalic looking parts of any of my cases are conductive, so that wouldnt have been doing any good.
