Hi MMO-C!
I'm changing my graphics card and RAM tomorrow (on a wooden floor) and after reading about grounding myself I'm a little confused. This is the first time I've done it. Does the computer need to be plugged into the mains but not switched on, or does it need to be unplugged completely? Keep in mind that my PSU doesn't have an off/on switch at the back.
I'll be touching the inside of the case to ground myself as I do not have a wristband.
Thanks!
