You can ground yourself with most computer models by touching the metal chassis inside the case. That is, provided the machine is turned off, plugged into a properly grounded outlet, and has a metal chassis.
My motherboard comes with a foam around it, should I keep it on just to install the Ram slots and CPU and then remove it for everything or remove it completely? Also, how do I ground myself before touching anything? An electrical engineer (irl) told me in order to ground myself the power supply has to be connected to the PC and be connected with a cable that has a ground pin. He then said you if you have a spare PC touching the back of the PC where the PSU is will take away static while it is turned on.Is the only way to ground yourself, is this efficent?
Can I touch any part thats metal on the PC and it will remove static or does it have to be grounded? An antistatic wrist strap is the best way, but yes, touching a grounded bit of metal is sufficient. With that said, ESD (Electrostatic Discharge) isn't really that big of a deal. I've been building computers for nearly 15 years and haven't ever killed anything with a static shock. It's actually hard to do and you have to be very careless to do it.
As long as you don't run around on a carpeted floor with only your socks on and then go and deliberately touch all of the ESD sensitive parts (the IC's, mostly), you're fine. I worked for 37 years for a large communications company, and we were disciplined if we didn't have a static strap on when we replaced circuit boards in ANY of the equipment.
We saw videos and pictures of what static can do to a circuit component (of course they were magnified or micro-scoped). The effect of static on a component doesn't always show up immediately, but over time it can cause failures. I have been building and working on computers since 1971 and ALWAYS use my static strap and work on an antistatic mat on my computer workbench. I suggest you do the same, or least neutralize yourself with the box you are working on. Better safe than sorry. Finally, a good answer - toolman0318 Explanation of just how much static you can build up. Remember You can ground yourself to a chassie, but as soon as that hand is removed 2 minutes later you can have a charge.
Keep inmind a CPU and Ram operate a UNDER two Volts. An it takes 500 and up just to know you had a charge. Also if you have a high build up you do NOT even need to touch the component, just bring your pinky close and it can be damaged. Look at two things in this link 1) amount of volt that can be built up - REMEMBER winter an LOW Humidity is just arounf the corner. Then Look at the two types of damage that can occur - Ever wonder just How many of the DOAs returned to companies are caused by ESD damage? And ther are many More.
Best grounding is to install PSU in case, Plug PSU into one of the power strips and leve turned off. Connect wrist stap to any UNPainted part on the case. I still say that if you're not a complete idiot, it's not really a major problem. Can it happen and can it cause damage that may not be immediately apparent? Absolutely it can, but if you don't act like a complete idiot and handle everything with no regard for the safety of the components at all, you'll be fine.
Just be a little cautious with how you handle the components and don't build in a room with a carpeted floor with no shoes on. That's all it takes. It's not some scary thing that any smart individual can't avoid with even a little idea of what they're doing. Edit: Maybe I give people too much credit. I don't know.
I mean, I know I know what I'm doing, and I never have had an issue with it. Never have been overly cautious, either (certainly never used a wrist strap).
Common sense is all it takes. Just don't be an idiot.

Sorry for bumping this thread, but Chief, you know what your talking about when it comes to static. I need to ask you, what is the proper way to ground myself and prevent ESD? Enter cheat codes ios.
I've heard I should use a wrist strap that connects to an anti static mat, then the mat should be connected to ground, yes? My problem is, will my painted case be grounded whilst its laying on the mat? Thanks, Paul.
My problem is, will my painted case be grounded whilst its laying on the mat? If your computer case is disconnected from the wall and on a non-grounded or non-conductive workbench/surface then your case itself is not grounded but that in itself is not a problem because by touching the case before putting your hands in it, you equalize the charge between the case and your body and bring the voltage difference, whatever it might be, to zero.
You can build a computer in an environment where everything is charged to several kV. You just need to make sure to equalize charge between components before putting them together. Pick IO cards up by the metal bracket, keep a hand on the computer case somewhere where aligning the card with the expansion slot and everything will be fine. Pick up DIMMs by the edges so any ESD will jump from your fingers to the PCB's power/ground plane, touch your case to equalize before inserting the DIMM. Touch the CPU's IHS before picking it up, keep a hand on the case while you line the CPU with the socket, drop the CPU clamp and now you can use both hands to finish the job.
The name of the game when working with floating grounds in an ESD-prone environment is to equalize charges before putting two components together. The wrist strap attached to the floating-ground PC spare you the trouble of remembering to touch the PC's case between manipulation but you still need to be careful about how you pick up your other non-grounded components. Yes, ideally a ESD mat and your ground strap would go to earth ground. What I do is Toke a AC plug and connected one wire to the round prong (ground) I then plug this into a power strip that is plugged into the wall. This becomes my 'single point' ground.
Not many have a ESD mat, So: Do not recommend using a Non-conductive material, like plastic/Styrofoam/glass, but wood is fine. NON there is some treated Styrofoam (normally green) that is excellent but problem is hard to verify that infact it is the treated sytrofoam. For most, first installing the psu in the case then plugging into the Powerstrip or outlet with rocker switch in the OFF position is OK. If NO bare metal, simply insert a screw into one of the case screw holes and clip to that. Yes, ideally a ESD mat and your ground strap would go to earth ground.

~ £50 - Expensive but it's a good size and it comes with its own uk grounding plug. ~ this is only £15. It's about half the size of the other and doesn't come with a plug. However I did see this being sold separately ~ ~ if I attach the ground cord to this it should work, right? Also, are these mats made of the same materials? I ask because I'm not sure if some mats are better at dissipating static than others. Thanks for your time.
Also, are these mats made of the same materials? Download gratis aplikasi coreldraw x6 tutorials. I ask because I'm not sure if some mats are better at dissipating static than others. The amount of energy that needs to get dissipated to prevent static buildup is miniscule. Many grounding cables even have a 100k-1M ohm resistor in series to reduce electrocution and short hazard in case you touch a live wire. All that grounding mats/straps need to do is bring floating local grounds which includes components, machinery and their operator(s) to a common (usually but not necessarily Earth) ground so discharges cannot jump between items since everything is charged to the same potential or 0V relative voltage.

Any ever so slightly conductive surface should easily provide sufficient conductivity for ESD purposes. Simply increasing humidity can increase the air's conductivity enough to prevent static buildup. So unless the mat/straps are fake, you do not need to worry about their effectiveness. I got my mat free. Probably would not speed 50 quid on one - I'd just cut a 3 ft x 2 ft piece of 1/4 in plywood.
