Which is best?
I've been told two different ways to counteract static electricity when opening my PC to add or reseat a card.
One person said to keep the PC plugged in and the power off because the ground (when plugged in) is the best prevention against static electricity. Another said to get a wrist strap or anti-static matt and unplug the PC.
Will you provide your insight?
Thanks

It is sometimes recommended to leave an assembled computer plugged in while working in the case. This is a safe practice in older systems but the ATX and NLX power supplies used today deliver +5v current to the motherboard whenever plugged in. This current can be dangerous. With modern power supplies, use an anti-static strap and/or mat with the power unplugged. T
I DISAGREE with the comment that you should keep a PC plugged in when you are working on it. This is DANGEROUS TO YOU and should not be done.
You SHOULD, however, use a WRIST GROUND STRAP to connect your body to the case of the machine. In the best scenario, both the wrist strap and the CONDUCTIVE mat on which the machine is sitting will be connected to EARTH GROUND. But the KEY THING is getting your body and the case at the same POTENTIAL and the strap between you and the case will do that nicely.

Sounds good to me. Thanks a lot.
Glad we could help.
As rid posted this info for the most part first, I will create a question to toss some points their way.
Thanks,

I should make this a new question, but I don't know that the same people would respond. I could have broken the award points up a bit BECAUSE I appreciate all of you spending your time answering questions*. I didn't because rid did not tell me to use a surge protector as a buffer(??). (I honestly don't know what benefit is derived from using a surge protector in the "off" position unless it lessens an impact, but I took you at your word. You've been here a long time and answer questions sensibly.)
* I looked at the number of questions I've asked (shame-facedly) and thought that maybe I could make a small contribution. So, I bought $10 worth of points last night. This isn't added for comment, especially because it doesn't help you directly, but I realize what a great site this is and I've often wanted to help somehow.
So, I'll give rid additional points if you'll answer this. Does it matter whether or not I keep the PC plugged directly into an outlet with the PC power turned "off" (using a wrist strap, as well), or are you going to stay with with your original answer: use both a wrist strap and surge protector?
Hopefully, I'm clear.

The general idea is to equalise the potential between yourself and the box, so even if neither you nor the box is grounded, you MAY be safe as long as you touch the chassis first. Putting both objects (you and the computer) at ground potential first is a good idea.
