Solved Can this PC be repaired or is it faulty electricity in Apt?

Specs: Windows XP
I have a hardware problem that I believe was caused by either a monitor or an electrical problem within the apartment unit I live in.

Whatever is causing the problem my old computer now tries to boot and it sometimes doesn't power on at all, It has to be an electrical problem within the home itself, not sure what it is that could be causing it.

Anyway can this pc be repaired? There seems to be a short in the motherboard or power supply or a shorted capacitor. When the pc boots there is a heat wave like pattern in the video/text, it looks similar to a heat wave you would see on the highway on a hot summer day.

Not sure what it is exactly with the electricity in the apartment unit...unless someone here is a electrician.

The only thing i can think of is that is the power outlets are sending a low-amperage current to the pc.

This has happened with 3 computers already. All 3 of them had the power supply fail on them because of something with power inside the home.

Anyway the main question is can the pc's be repaired or no?

A plug in outlet tester will tell you some important facts like hot/neutral reversal and ground fault problems. Since they are not expensive, it will be a good place to begin. If it does reveal problems with the one outlet, check all of them in the home. If it is only the one outlet, and you understand these well enough, you MAY be able to rewire the outlet, if it is in more than one outlet box or you are not qualified, get a licensed electrician in to do a thorough testing and remediation. for the building. If all outlets test OK this way, that does not rule out other possible building and power system problems, but it will pick up on the most common, especially those made by amateurs trying to do electrical work (previous home owners and landlords) when they only half understand what they are doing.

You have to be a little bit crazy to keep you from going insane.

Hi So-Unfair, anything can be repaired if you are prepared to pay for it.

With queries such as this, always advise the make and model number of the device concerned.

As this is the 4th pc to fail, you advise *ALL* with suspect psu problems, you need look to find and cure the fault, otherwise there will be 5th and 6th failures, etc.

You mention the monitor:-
a) has it been changed?
b) is it powered from the base unit, or a wallsocket?

As a matter of interest, where (city/state) are you located? I am in Hammersmith, West London.

You suspect the house wiring, is having correct polarity and a good earth required in your location?

I would start by installing some form of inexpensive surge protection, feeding everything related to the computer.e.g.base unit, monitor, router, printer. Something like:-

Although I prefer to have a switch on each socket, which on this example is missing.

You live in an apartment - is there a lift?
These are known to cause power supply fluctuations.

Please advise back on progress.

Good Luck - Keep us posted.

Seems logical that you should check the voltage in your apartment.

Your logic is faulty. There can be MANY reasons why the computer does not always start.

Next time you have the computer up and running, download HWMonitor and run it in real time. Check the voltages and temperatures. the 3.3V, 5V and +12V should all read within +- of those numbers. IE- +12V should be within 95% to 105% of 12V or 11.4V/ 12.6V.

Get HWMonitor from the link below.

IF it is the power in your apartment there's a few things you can do before calling the electrician. You can get an AC line tester that plugs into your wall socket to check that the wires are where they're supposed to be. They're available at places like Radio Shack. Or you may have something called 'dirty AC' which is when the wave form is corrupted by noise and distortion. I know Radio Shack has AC interference filters which may work for that or you may need something specifically designed for dirty AC. By the way, these filters aren't the same thing as a surge protector although it's possible a surge protector may have a filter added as a separate feature.

You do not have enough fingers and toes to count the possibilities. Your answers will only be as useful as facts you provide. Since you did not do anything to discover what specifically failed in each machine, then your replies will be just a speculative or bogus.

Electricians can tell you what must connect to what. They are not trained to understand what happens inside electronics. Best evidence starts with the dead bodies. That's why murder investigations always do an autopsy. Specifically what part in each computer died? Otherwise you can only get wild speculation recommending a surge protector.

Either you find what specifically is the problem by identifying failed parts. Or just shotgun - keep buying new power supplies, surge protectors, and computers until something works. Those are your only two options.

BTW, view numbers. The power circuit must supply at least 15 amps. Your computer only consumes about one amp and rarely if ever two amps. You must learn facts and numbers before accusing any suspect (ie low amperage current from a receptacle). Start by doing what you have not yet done. Only collect facts. Solutions come much later.
