for static electricity you just touch the bare metal case before touching any circuit boards is all you need to do.
skybird you should take out the memmory sticks and the video card and wipe the contacts with alcohol and blow out the sockets with canned air before reinstaling them. dust gets into all sorts of places you wouldnt think and it could just be the contacts got dirty or oxidized and need cleaning to make a good connection again.
there is also the possibilty you power supply is going bad and you temporarily lost power to the video card so if it happens again test the voltage to the card before going buy one.
