When do I know when it is time for maintenance on the computer?

You seem to have missed my point:

Touching your metal case to ground yourself? | Tom's Hardware Forum

"Provided the case is electrically connected to earth via the above mentioned components, the static electricity will discharge via the case to earth. There will no longer be any static electricity on your person, until you move around on carpeted floor when static electricity will once again build up on your body. So for this reason, after moving around on carpeted floor touch the earth case with both hands to once again discharge the static electricity.

If the case is not connected to earth (for example PSU cord withdrawn from power socket; or PSU removed from case) then the static electricity will NOT discharge because there is no direct connection to earth/ground. The static charge will still remain on your body."

I didn't say anything about not wearing a wrist strap, etc. and taking other standard precautions, just that I want my chassis grounded when I'm inside it.

A grounded chassis has a earth grounded direct path for ESD to flow to when I touch the chassis.

If I didn't have a wrist strap, ESD mat, etc available, the one thing I would do is have the chassis grounded via the power plug as I described before prior to working inside it.

...but...but...but, @Steve ... LMFAO

Further down in the same forum, there is this post that concurs with what I fist said.

I'll post it here anyway as it's a good read:

Touch your case frame. you're grounded, now. you'll discharge nothing into the motherboard.

and the people talking about power plugs and grounding are mixing up 2 different things. plugging in the power supply grounds the electrical system. it has NOTHING to do with the person putting stuff into a case. the case itself is a grounded object by means of the Faraday Cage effect. it does not need a connection to a plug, or being placed on the ground or any other trick to make it grounded. touch the frame of the cage will make you grounded as well (as long as the case is made out of a conductive material this is true anyway, read up on faraday cages to understand this better)

note: the anti static wristbands connect to the computer case "frame" they do not require a psu being plugged in or the case being put in any special location to work.

When i work on a pc. I've grown accustom to keeping some part of my bare arms touching the frame of the case whenever i handle electronics. In 20 years of building and working on the insides of a computer I've never damaged anything with static electricity, when i work on the insides of a computer i do it with the power plug disconnected, this is my job. I do it daily.

Any come back my friend?

Heh, food, try ice-cream of chocolate, gin with tonic does not help either, sugar gets all sticky.

Should I drop some salt in my keyboard to prevent the ants ?

Tell me where the charge is going if your case isn't grounded via earth ground?

Unfortunately people can't see ESD, like viruses, so don't want to believe it's even a real concern...........

"oh, I've been doing xyz for years with no problems" ...........

ESD damaged components continue to work, until they stop working. I've seen xrays of ESD damaged components as part of years of required ESD training. ESD damage may not kill a component today, but its life may be severely reduced - as we were constantly taught as part of ESD training.

So my good friends, I leave it to you to decide what you will do now.

For those who want to learn about ESD ............. might be useful

When working on a car, why does a welder attach an earth to the chassis when the car has rubber tyres insulating it from the ground it stands upon? And, if they don't do that, bad things happen very rapidly. Electrical components get fried.

Touching the (metal!) chassis of a computer case works on the same principle.

It might not make sense, but it is how it works anyway. I only wish I could explain myself as it does seem mysterious.

Does this shed any light?

Time for a Gin and Tonic?

Cheers And I leave it to you to decide what to do ........... I don't have an electron flow video camera

Ha ha. I'll join you. You're a great guy Steve ... ... and make me laugh.

I always take maximum precautions ... except when it comes to making babies. My father did not not want to insulate himself in that respect. Said, "It's like having a bath with your socks on." Then he said, "Trouble is, whenever I hang my trousers on the bed post, there's another one of you on the way."

On that note, HIC,

All the best peeps.

My maintenance practices is once a month do my system dusting to best of my ability allows me to, using both Cordless Duster and Plug in Air duster X-Power with the different attachments to get it as clean as i possibly can

Software maintenance done weekly in terms of backup, chkdsk every 3 months, memtest86 once a year, in General these have keep my systems running good the last 5 years.

I'm no way like i was in 2005-2017 where i rarely remembered to do maintenance, nowadays i pick Saturday or Sunday to do my maintenance so i don't forget, and so far has worked very well, no one system hardware or fan failure in a long time now

2005 was very very bad experience, had a PCI slot fan in the system to try and keep older video card cool-got so dusty, caught fire, and burned out the video card, chipset as well, Had Abit NF7 Motherboard then. Back then i didn't do proper maintenance, now i do though and make sure i do alot


Was testing at the time WIndows live one care, listened to a so called friend in a game, and tried see if Windows Live One Care would detect and remove the files, ended up infecting that older system with boot sector, trojans, worms, and killed hardware lol as well

got it rebuilt and been better on maintenance since

Nice post @AMDMan2016

@CMArbres,

Chris, would you rather stand next to a properly grounded lightning rod, or one with the grounding not done properly/disconnected?

You must pick one and you are bare footed in an ESD storm
