Hi,

I'm running Windows XP Pro - 1gb ram - P4 3.0 ghz hyperthreaded - Intel Desktop Board D865GBF.

I've got a strange problem. I think I know what's causing it but I can't figure out what to do. My computer will reboot sometimes when I leave it idle for a few minutes and I come back to it and touch the mouse. Soon as I touch the mouse it reboots. The desk my computer is on is one of those glass ones with a metallice frame. Sometimes when I touch the metal and get a static shock the computer reboots. Another computer across the room which is usually hibernating comes back from its sleep state when the first computer reboots. I can't really pinpoint when this is started. I'm guessing it was after a video card change. The new card didnt work so I put the old one back in and I think this has happened ever since. I've opened it up, disconnected and reconnected everything. Nothing seems to help. Sometimes I can go a whole day without a reboot but usually I get 2 or 3 a day. Some reboots happen when I try to plug in a USB device. As soon as the USB cable touches the connector it will reboot. Other times the mouse tracking slows right down. Then I have to disable and enable for it track normally again. I've checked all my connections on the motherboard. The grounds are connected correctly.

Hope someone can help!

Get a new desk or an acryllic PC case.

In the meantime, you can ground your case using an antistatic wrap.

Well, I just checked your profile, and I can see that you live in the Great Frozen North, where this is not an uncommon problem during winter. I'm sure you live in a nice warm house, and that is part of the problem. You have to have the heat on to keep from freezing, and that makes the air in the house warm and dry. Warm, dry air is VERY conducive for static build-up under those conditions, but since I grew up in a cold, snowy area myself, I can tell you how to solve this problem WITHOUT buying a new desk OR an acrylic case (which is absurd, if you think about it).

Get an empty spray bottle, like the one that window cleaner comes in. Rinse it out THOROUGHLY, and put about one teaspoon of dishwashing liquid into the bottle. Next, fill the bottle with warm water, then, walk through the house, and spray the rugs and carpets with the (mildly soapy) mixture. You won't hurt the carpeting AT ALL, as long as you DON'T use a product with a bleaching agent in it, which means, DON'T use LAUNDRY soap, which MIGHT have some type of bleach in it.

A light mist of the mixture on the rugs and carpets will do the job for a day or two, and you'll quickly figure out how much to use, and how often to apply it. You DON'T need to SOAK the rugs; you only need to DAMPEN them enough to eliminate the static, and that will help you stop suffering from the spontaneous reboots, and from shocking one another as you walk through the house. Once the weather turns nice outdoors, your static problems indoors will disappear until NEXT winter.

Good luck; try this and let us know what happens. I'm willing to bet you'll notice an IMMEDIATE effect on the amount of static in the house, and an end to the spontaneous rebooting of your systems.

How absurd is it if it provides a permanent solution to his problem?


An antistatic chair mat would even suffice to permanently solve it.

Actually gentleman, the "proper" permanant fix is R&R (repair or replace) the furnace humidifier

Or if necessary, augment the furnace humidifer w/ additional room humidifier

Sean B:

First of all, OCGW is correct on BOTH points; RAISING the humidity WILL solve the problem, (which is EXACTLY what MY solution accomplishes), and what would ever make you think that an acrylic case would REDUCE static? IF you don't have any actual knowledge of electronics and static conductivity, you really shouldn't give anyone "advice" like that. An acrylic case would be the WORST thing to use in this circumstance, because it would actually HOLD a static charge up to several thousand volts higher than a comparable METAL case.

Since you don't REALLY know anything about the subject, you shouldn't be giving advice, because you CLEARLY aren't qualified to do so. During my undergrad years, I wrote an extensive paper about the effects of static in the computing environment, followed by one the next semester, titled "High-Electron Mobility at the Sub-atomic Level"; do you STILL think you know more about static electricity than I do?

If you DON'T KNOW something, then remember that it's better to remain silent, and be thought a fool, than to open your mouth, and remove all doubt. That bit of wisdom has been credited to Abraham Lincoln, among many others, and now I've taught you even MORE than you've ALREADY learned today by reading my original response to this thread.

Ignorance might be bliss, but you have no excuse for that; fire up Google, and get an education BEFORE you decide to "contribute", OK? You're REALLY not helping people with "advice" like that, whether you're willing to admit it or not. Your "solution" was not only worthless, it is also irresponsible; acrylic is the WORST material for building a static-resistant computer case I can think of offhand.

OCGW:

I live in a warm climate, I've never turned the furnace on here in the twenty-three years that I've owned this place, so I didn't know that furnaces even HAVE a humidifier. Thanks for contributing; you've taught ME something new today, which I always appreciate.

My solution was the low-buck way to resolve the problem, and yours was the BETTER, though somewhat more costly approach. Thanks again.

EDIT:

Darshan Daurka:

I hope we haven't confused you with all of this, but you can EASILY find the TRUTH by doing a little research with Google. Good luck; let us know if you have any more questions about this.

Usually the furnace humidifier is fed water to a tank w/ a float like a toilet water closet tank, sometimes the line is merely "tapped" off a pipe, & the pipe gets plugged w/ rust, or sediment and just needs to be blown, or poked out

Before I got in to the Automotive Engineering field and started w/ GM, I was a Pipefitter (Pipefitter/Steamfitter/Plumber) w/ Ford Motor Company

I took Heating & Cooling, Pipefitting, Plumbing, Hydrualics, & Pnematics @ Henry Ford Community College

You a correct Pat, the lack of humidity in the air "encourages" build up of static electricity

Cold air doesn't hold much moisture, & furnaces make it worse by drying the air further, that's why they put humidifiers on furnaces in the first place

It also bad for your respitory system (catch colds)

Reminds me of a thread where a guy said that acid in this room (on his job) was eating up his comp every 6 month's

Everyone was trying to give him advice on how to protect his comp

I said, " F**k your comp, I am worried about your health, you need better ventilation, & I bet if you call OSHA
(Ocupational Safety & Health Agency) here in the US, your company will fix that s**t quick, fast, & in a hurry

Edit: Yo' Sean, one of the "classic" static electricity demonstrations is to rub wool on a plastic rod, it will then strongly attract oppositely charged materials

Hey guys,

Thanks for the advice.. I actually picked up a portable humidifier and it seems to be doing the job just fine... so far!

Thanks again.

OCGW deserves all the applause; I'm MUCH too cheap to spend YOUR money to fix a problem like that, so I'm grateful HE suggested opening your wallet. I would have opted for the spray bottle, because it's a great way to convince kids and pets to leave the area.

Glad to know he was able to help you resolve this; having a former pipefitter in these forums sure came in handy

WoW, thanks Pat

We all like a "pat on the back" once in a while

You know, moisture in the air makes it feel warmer, not bad in the winter

Darshan Daurka, glad it worked out for you

Hey, how much did the humidifier cost?

PEACE

My buddy one time was trying to install cold cathodes, and he didn't want to drill a nice hole for the switch,
so he pried apart an area on the back and created what could only be called "a bitch-rigged" hole for the switch.

Well, he didn't quite notice that the contacts on the switch were also in contact with the case, so when he said "Here we go!" and switched it on, not only did the lights not come on, but his case shorted the circuit and his whole PC shut straight off. :)

He's lucky he didn't permafry anything.

Arcing and sparking; I love it! Hey, G., your friend is a riot! A good friend of mine decided to try to jump-start his motorcycle with his Jeep; I tried to talk him out of it over the phone (I was away on a business trip), but he was convinced that he knew what he was doing, because he had seen me do the same thing two years before (we were next-door neighbors).

As you've guessed by now, he incinerated both the Jeep AND the motorcycle; his wife was so angry, she had them both crushed and left in the driveway while he was at work the following Wednesday. She hung a sign on them that read, "Beware of Husband", and dozens of people came by to have their picture taken while standing in the driveway between the two burned out hulks, ESPECIALLY women. The junk was gone the next Monday night, but the wife got her point across, and the neighbor decided that sometimes, discretion really IS the better part of valor.

In fact, something good came from all of that; I introduced myself to one of the women (a flight attendant) who showed up that Saturday, and we were together for more than four years, until she transferred to another city, to be closer to her elderly parents. After she moved, I asked the neighbor if he was planning on incinerating anything else; I figured that was just as good a way as any to find a new girlfriend!

The humidifier cost me about $70 CAD - but turns out it didn't help. I'm getting shocks again and my motherboard seems to be dead. My computer no longer posts. I went to move the mouse, I heard the little pop in the speakers and then I heard 2 or 3 crackles on the motherboard. The computer restarted but didn't post. I guess I have to return the humidifier! I should've just tried the spraying thing first. I'll try that this time but now I'm not sure what to do about the motherboard!

I had (and still have) a similar problem. I have gone through 3 motherboards. My problem however turned out to be that my wall outlet wasnt grounded properly. Everyone occasionally gets static shocks, but for your computer to shock you so frequently (as mine was) it suggests to me that it isn't that you are building up charge every 5 mins but that your outlet's wiring may be funky. You should do a few things:
1) If your computer is plugged into a surge protector or a UPS, get a new 'not cheap' one just to make sure that that isnt whats responsible for your lack of grounding.
2)Verify that your wall outlet is properly grounded. You should ask an electrician to help you out with this. My problem was that my computer would randomly become charged and shock me (and fry my motherboard), and then at other times (in between motherboard replacements) be perfectly normal. When you test the outlet you should make sure nothing special happens when you actually draw power from it. You dont want to just be satisfied by saying its grounded when nothing is plugged in.
3) Make sure your power supply isnt faulty.
4)If indeed you are the static carrier and your computer setup is fine, get an anti static wrist band. It helps! You ground it to your case and put it on your wrist. It slowly grounds any charge that you may have built up through the case and into the grounding wire. If your wiring is fine it shouldnt affect your motherboard at all.

Hope that helps!

P.S Check if your motherboard is under warranty. You can RMA it back to them and ask for a cross shipment. You could ahve a working motherboard in as little as 4 days!!

There could be an earth problem, check that the mainboard is not touching the case bottom etc.

I'm not sure about the GWN (Canada), but that third (roundish) do-hicky on the plug is supposed to be ground. You can get a cheap little device called a Ground Fault Tester, to see if you are getting a good ground. I've seen these deltas when the computer is plugged into a UPS (which isolates the ground plane through transformer to give a pseudo ground) and having other devices plugged into the computer that did not share the same "float". Same problem on building to building copper networks by the way.

So it may be a ground float, vs. static issue.

PICK A SCREW!

Run a chassis ground wire between all peripheral devices and the computer, and desktop as well.

Any case screw on the computer that makes metal to metal contact to the desk leg, to the printer, etc...
This will take care of the static issue as well as long as that third plug lug actually makes ground.

Not as absurd as your suggestions. First, you can't ground ANYTHING in anti-static wrap. You are insulating the object, which is the exact opposite of grounding it. You COULD insulate the computer from touching a metallic part of the desk (or just keep all metal components on the glass) but the mouse will still be a problem unless you get a wireless one.

Secondly, an anti-static mat won't help matters either unless he LIVES on it. If he gets up and walks across the room and builds up a nice 200,000 volt charge on his skin and steps onto the mat, he will still have the charge which will then DISCHARGE as soon as he touches metal again. Anti-static mats ONLY prevent you from building up a charge from the movement of one's chair and feet across a carpet.

MY suggestion to YOU would be to learn a little about electricity before you continue making suggestions that might cost people (who are under the false impression that you know something of which you speak) money.
