I have to work on a power point about computer electrical safety. I have to have several points on power supply safety and the internet hasn't been much help, so I thought I'd try here.

I'll try to be simple, because its trial and error.\nYou need to ensure that the intake and exhaust vents on PSU is clear of debris or dust. Clogged vents slow down intake which could stop the fan and overhead the PSU, shutting down the system.\nMake sure all the power supply cables that run to the mother board and drives have no cuts that may expose wiring, which could cause a short or fire.\n\nDo you need SEVERAL?! because the PSU is a simple part of a system, and doesnt have that many problems for safety compared to all the circuit boards on the Cards and the Mother Board, and the Drives. Just make sure to point out the fans need to be clean, and the vent, to keep the PSU cooled, and the wires should be free of nicks, and try to not tangle the cords, that may cause kinks in the power cord, which affects power and performance.

How refreshing. Someone with a credible degree asking an honest question on these teenager boards.\n\nGoogle it and use your engineering brain to come to a conclusion.

Sounds to me like the voltage switch if you mean the little red one that looks like the one in this picture:\nhttp://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-4Y67VN\n\nThat will require a trip to a computer store and likely some new hardware. Possibly just the power supply ($50 or so) but perhaps much more; like the motherboard/CPU and RAM. The PSU probably got more voltage than it should have and the 'magic smoke' that makes it work leaked out.\n\nGood luck.

check out your power box in it ..may be its has got some problem.

i tend to agree.. i have been a pc jockey for a bit too long myself and its occuring more and more to me lately that there actually is a world outside.  sometimes im shocked when the sun hits my face, so maybe it's time to stuff the box in the closet and take out my walking shoes.  id like to write a book too, but i find the time passing on the internet most days, then another and another.  thing is, every day is the same on the internet and there doesnt seem to be any real point to it.  hm

Take it in to a shop and have them look at your power supply. It sounds like that could well be your problem. If so, it is a fairly easy fix. Trust me, it happens way too often of late. Good luck.

could be a power supply or overheat issue

200 W is not much for modern computers.  I assume that if you don't add anything, things keep working.  The power supply need not explode or catch fire.  More likely the voltage levels drop under overload, and things stop working.

The power supply might have gone out.

In a purely resistive circuit, the power factor (PF) is 1 and you *can't* adjust it.\n\nAnd, since this is the 3'rd time you've asked the question and gotten the same answer from one other person and myself, do you even know what 'Power Factor' *is*?\n\n\nDoug

You probably experience a power surge if your PC was still on your power supply unit is probably fried.  Power supplies usually aren't that expensive to replace, especially if it's on a PC such as a Dell, HP, etc.  Newegg.com is a good place to start you probably won't need more than 450W, so just replace that and if you're not familiar with computers bring it into a computer repair shop and have them replace it.\n\nHope that helps.

what if your computer is a female... and you know how finicky females are!\n2 things....\n1 is your computer sitting on the desk or on the carpet? if its on the carpet, put it on the desk. that can kill a computer with static electricity and it will freeze every time it gets a jolt.\n2 I am thinking maybe a driver conflict (if its not on the floor) run a reg cleaner....something like PC Bug Dr. also check configsys to see what all starts when you turn on the computer, do they use a different media player than you or a different browser?\n\nwith more info I could fix your computer in a minute or two\n\n-Doc-

i swear to god... if you goto Cnet!!!\n\n\nwww.Tomshardware.com \n\nis where you go for real reviews. where they really test the hardware.\n\n\nlol last month they took all the hottest power supplys.. and ran them at 100% for 14 days. day and night. \n\n1 caught fire!!! \n\n2 smoked!!!!\n\n\nsupertech has a point too.

a 400 to 500 watt power supply would solve the problem

just a crt and some mostly random web content i think. It works for me. 20 minutes or so, a crt and a pc, maybe half a kilowatt hour.
