      I'm not surprised that PSU related problems is on top seeing how it's the most important component of the computer but the one that people seem to pay the least attention.

      What people must understand is that they need a PSU that have the most stable rails (such as the +5 & +12 rails) and that isn't made by Mr. Bingo Bongo. Sure you can save around $20-30 going with a cheaper PSU but that action is a gamble. Are you a gambler? My friend sure was. Bought some power supply made by some unknown manufacturer and he's still surprised that it was the cause of his exploding CD-Rom.

      People in general should take power supply reviews more seriously and consider to spend the extra bucks to hafve something that will work for years as you want it to.

        Abso-fricking-lutely correct.

        The spec's written on most el-cheapo Chinese PSU's are about as accurate and truthfull as the wattage claims written on the box of those $25 "1000 WATT" PC speakers you bought at the local PC market. The difference being that if you blow up your craptastic speakers you just need to buy new speakers, but a bad PSU can cause you to re-purchase a completely new PC.

        It amazes me the number of "tech heads" out there who will pay AU$900 for a top of the line GPU (just to gain another 3fps in Doom 3) but will try to run it and their P4EE off a $15 SangChoyBow "500 WATT" powersupply.

        Incredible.

        I'm not surprised that PSU related problems is on top seeing how it's the most important component of the computer but the one that people seem to pay the least attention.

        At one of my jobs, a client had a lab full of fairly new computers with cheapo supplies. I kid you not: within 1 year, 25 out of 40 supplies failed and in three cases the motherboard and CPU were destroyed in the process. When I came onboard, I made it a policy that any machine found to crash at random would immediately have its supply yanked and replaced with a quality one. (indication of pending failure..) User complaints dropped rapidly as reliability instantly went up.

        What people must understand is that they need a PSU that have the most stable rails (such as the +5 & +12 rails) and that isn't made by Mr. Bingo Bongo. Sure you can save around $20-30 going with a cheaper PSU but that action is a gamble.

        It's not even just stable rails. (although this is one indication of quality..) I've found by examination of fried supplies that the cheapo varieties don't have much in the way of protection circuitry. All power supplies die at some point. That's a given. The quality ones just die gracefully and don't take the rest of your hardware with them.

        As for price, the amazing thing is that there's not always that much difference between a quality budget supply and a total garbage one. I've found 300W Fortron (FSP-300) supplies in the $25-30 range. They're not top of the line, but I've yet to have a problem either.

      Last week's issues:

      #1 - Call from remote office. Server isn't working.

      Office manager was cold, so she bought a 1500W electric space heater. She needed a place to plug it in and there just happened to be an empty outlet on the UPS that fed the server, which was conveniently located right across the hall from her office.

      Plug in heater, heater kicks on, high current starts, battery backup melts down, and server goes into SSF mode (Sparks, Smoke, and Flames). RAID card burned out and the machine is pretty much toasted. Defintely a power issue.

      That office needed a new server anyway.

      #2 - Call from dentist's office. Computers won't connect to the network and they are getting weird errors. Drop by office to inspect. Reboot computers and everything seems to work fine.

      Network swtich and router are located in a cabinet in the darkroom. There is a single cable that comes out of that cabinet from the UPS that feeds the network equipment. They are short on outlets in the darkroom.

      When some of the employees need to use the film duplicator, their solution is to unplug this plug that doesn't seem to connect to anything important. (Never mind that beeping sound in the background!)

      Network doesn't instantly fail, since the equipment stays on UPS for ten minutes. Since they don't have instant feedback to realize that what they're doing is bad, they never associate the bad action (pulling the plug) with the bad event (all computers quit working).

      Power issues. Yep. Sheesh!

      The number one killer of PC's, IMHO, has been the modem.

      Lightning usually doesn't even have to enter into it. Everytime the phone rings you get voltage running into your PC.

      Once I heard a long ring and the PC never turned back on (well, for a year at least. Later the machine was revived but using any PCI slot mysteriously disabled DMA. On a 333Mhz machine you can imagine boot times).

      Another killer was USB related too. Microsoft's Trackball Optical [microsoft.com] cable shorts out occasionaly which for some reason killed my $3000 custom-built PC about 3 years ago. Someone here on Slashdot told me I can get a refund or some sort of offer but it wasn't worth the hassle.

      • A former roommate told me a story about how he'd killed one of his computers. Seems he left the thing on the floor in his room.

        Now, his living spaces tend to be trash heaps; it was only constant nagging from his ex-fiancee and me that kept mold from growing in their room when he was living with us. So this did not surprise me at all when he told me what happened...

        For whatever reason, ants decided to visit his computer. Ants. I guess he might have spilled something in there, probably Mountain Dew. He saw the ants crawling in and out of his computer, didn't pay much attention to it, and turned the thing on.

        Poof. Fried.

        I laughed at him.

        An ex of mine wound up with a few extra chips in his computer (chocolate and dorito) owing to leaving it open, but never before or again have I heard of ants infesting someone's computer.

    Back in Highschool the 386 and 486 pcs had the old standard keyboard lock. By rubbing your shoes on the carpet, lifting them up and holding your finger milimeters away from the metal keyboard lock a static discharge would then hit the lock. Monitor would go black and an instant fried motherboard was the result. The school just kept replacing them under warranty claims. And these were dropping about the rate of one or two a week.

            No freaking kidding. I've been at my current job since I got out of college a little over 2 years ago. After working for a couple of months, I had to go to the first session of some bogus training for young engineers, set up so the new blood from all over the company could mingle and network. I was *shocked* when one of the multiple-session veterans talked about how they'd just about destroyed a rental car on another trip. He condescendingly explained that another time he'd told that story, someone had freaked out a little, because they were too inexperienced to understand that the cars were insured and it couldn't come back on you.

            When kids are 12 years old, I can see it a little, but 22-25? Cripes. I wanted to punch him in the head and it wasn't even my car.

I've pulled several working PCs out of the "trash" (NYC curbside - cleaner than a dumpster, dirtier than a Toronto dumpster).

      Unfortunately, that's not always the case. This assumption was a pet peeve of mine, when I used to work in the computer repair business. I'd have some guy talking up the specs on his computer, and they would usually be impressive up until he bragged about the 450 Watt PSU that he picked up for $35.

      Not only do cheap PSUs introduce stability issues, but a lot of PSUs take things down with them when they blow.

      My favorite example is an absolutely spectacular one involving my brother's friend. He had a 1.4Ghz Athlon (back when that was impressive), along with the requisite DVD, CD-Burner, brand new GeForce 3; the whole nine yards. The PSU blew. Both optical drives ejected and shot sparks from inside. HDDs presumably lost their motors (they never spun up again). Mobo died, CPU died, sound card died. The only thing that survived was the video card, which was at least a small consolation since it was still top-of-the-line.

      PSU replacements did tend to be my second most common hardware repair (HDDs were first), and most of the time they didn't damage anything, but I saw enough problems then that I'll only buy reputable PSUs now.

    I had a Commodore 64 for years, it suffered through insane adversity. My mother threw it across the room in a rage when we wouldn't come to dinner, my dad dumped an entire can of beer into the heat vent by accident when he was checking his wristwatch. It was dragged off a rickety TV dinner tray when cords were tripped over at least weekly. It always still worked. That thing was built like a tank. In the end, the power supply died.

    Yeah, I know it was replaceable, I didn't have any money.

    Just a couple of weeks ago a PC nearly burned down the house. I was out the front and heard frantic calls, came round the back to find smoke pouring out one of the windows, I mean thick acrid black smoke. Neighbours had already called the fire brigade.

    Anyway they arrived in a couple of minutes and went inside and put it out. Luckily there were two windows open and a good breeze blowing in one and our the other so the damage was minimal (all smoke went straight out the window).

    The PC was completetly incinerated though, I've never seena anything like it, the hard drive was actually warped from the heat generated in that steel case. The plastic fascia was gone, just, not there any more, the motherboard, well what loosly resembled one was pretty much ash. The solder holding the ICs obviously melted and they had popped off etc. Luckily, it wasn't my PC, and it was only an old P200 or something, or I'd be up shit creek.

    It burned right through the carpet immediatly under the case, and burnt a good impression into the wooden floor beneath. Burnt a chunk out of a couch next to it, but it was caught early enough that there wasn't really any other damage.

    I can't see what caused it, the heat generated inside the case was incredibly intense, basically anything inside it that could vaporise, did.

    Let it be a warning - install smoke alarms near your PC if you leave it running unattended.

      I am starting to wonder if these PC fires might be due to the "exploding capacitor" problem from that era (where the Taiwan company that stole (and miscopied) the recipe for making capacitors, which then, after 5 years or so, pop, spilling eletrolyte all over a running PC motherboard).

      I have read around the net recently several cases of fires happening (but someone was near the PC and shut it off right away, then saw where the smoke came from (around the board where the eletrolyte had spilled out of the pop'd capacitor) after opening it.

      Urban legend or is this going to be more of a problem as PCs from this era start exhibiting this problem more as their capacitors 'expire'?

    Ok, this actually happened.
    One day our secretary comes to me and says her keyboard isn't working properly. I just assume it died naturally and so I grab a replacement from a pile in my cupboard and hand it over. 30 minutes later she comes back and says that the one I gave her is broken too. Now that seems strange, so I go to her system and do a full check, thinking that either her motherboard is faulty, or something is shorting out the keyboards, or she has some practical joke walware like the old Amiga virus which re-mapped keystrokes but only if you typed fast enough. After a thorough check, I confirm her system is OK and both keyboards are indeed dead. I take another spare keyboard from the cupboard, test it on my computer first to make sure it works properly, and then give it to her. 5 minutes later I decide I better check to see if it's OK, so I walk over to her desk just in time to see her take a bottle of spray'n'wipe, spray a massive amount directly into the keys, wipe them off, then bang the keyboard upside down against the edge of her desk to dislogde any dirt which may have been there.
    The 3rd keyboard she got that day was a new one so she didn't have the urge to clean it. It still works.
    The funny thing is that I felt an immense sense of relief knowing why they broke. 3 keyboards "mysteriously" dying in an hour is something I don't understand and makes me nervous, however stupidity is something I do understand and just accept.

        At first I thought maybe you were in the same dorm I was. One of the guys down the hall wanted a new computer, but wasn't experienced enough to build it from scratch, so he paid my roommate to build him one. So my roommate buys all the components online, and a couple weeks later we assemble it to make sure everything works before we put it in the case. Everything works fine, so we stick it in the case. Turn it on. Nothing. We pulled out all the extra cards. Nothing. Swapped video cards. Nothing. Processor. Nothing. My roommate goes out and buys a new motherboard, assuming this is the problem. 3 returns later, the system still doesn't work. Worst part is, all the components work when they're not together (after further testing, none of the "broken" motherboards were in fact broken).

        Eventually he just called it a loss and sold all the parts to other people in the dorm (I still use that sound card too!). Later I discovered that the case itself was cursed. Not even kidding! Nothing would run out of it, ever. It has the amazing ability to render any setup inoperable, even with a new PSU. Discovering this, I of course did the logical thing and gave it to a guy I didn't like very much who was building a computer himself.

      I knew a sound engineer who would clean out mixing decks with sprite. He would just dump it down the fader slots. I managed to get him to switch to plain tonic water. The theory being if you did not have it plugged in or on the liquid would not conduct and the carbonation would remove grime sticking the faders. You just let it dry before turning it back on and all would be well.

      I only witnessed this act twice and it still gives me shivers.
