Strange computer problem

    I just started noticing an extremely high-pitched sound emanating from my computer even when it is turned off. It's the type of ring that you might hear after a loud rock concert (tinnitus). If I disconnect the power cable from the CPU, the sound fizzles out. Could this be something in the power supply? It's not as noticeable when the computer is turned off with the fans running and all. Maybe someone here has had a similar issue with their computer. Thanks!

    I had a power supply that did that same exact thing. As I sat and contemplated whether or not it was the power supply, there was a little pop and then smoke wafted from the back of my puter.

    I'd change that bad boy out.

    almost certainly a problem with the power supply. It's probably a sign that it's on its last legs. If I were you, I'd replace it ASAP, a failing power supply can take out other components when it finally fails... Could be the monitor too, but I've never heard one do that when it's off.
  6. Does it slow down gradually when you shutdown? Maybe the fan?

    I recently had this problem with my old PC. Unplug the cord, it was fine. It is most definitely your power supply, a capacitor is probably going in it and that's its way of telling you that it is dieing. Get a new one for your PC that fits your cases' form-factor (usually ATX will work fine) and put it in ASAP, because if that blows on you, you risk the possibility of damaging other components in your PC, and overtime the probably unstable voltages from your power supply will slowly but surely kill your components.

    EDIT: Please DO NOT open the power supply and try to "fix it yourself" unless you know how to properly ground a power supply and what not to touch when it's open. I guarantee you will get yourself killed as a lot of power remains in the power supply even as it has been off for some time. It's best to just leave it alone and get a new one, they are fairly inexpensive, and I'll recommend you one that I put in my old PC, that has plenty of juice and is a very inexpensive and quality brand... http://www.newegg.com/Product/Product.aspx?Item=N82E16817153023

    Thermaltake is a very good brand, and 430W should be enough juice for your system depending on what you do with it. I also use a bigger version in my new gaming PC, Thermaltake Toughpower 700W :D.
  9. +1 on power supply

    I didnt pay attention when mine was doing it. The over the course of the next week two ram modules, a harddrive and my graphics card all fried. Then the PSU wouldnt turn on anymore (once everything was removed) :(

    Wow, I never got email notifications to any of these replies! Better check my profile! I figured it was the power supply. What sucks is that I just put this power supply in less than a year ago when I upgraded to a new monitor which required a separate graphics card (original PS didn't have enough juice to run the new monitor). I'll have to check if it's still under warranty. It's been doing this for about a week now. How much longer until it goes you think? Thanks for the responses, BTW!

    No estimate on an ETA for failure. It might fail today, It might never. Sometimes cheap PSUs have equally cheap capacitors and/or transformers that can cause that high pitched whine. But, if it didn't do it when you first got it, I'm betting that it WILL fail.

    What brand is it? This is one of the components that I wouldn't cheap out on. Besides, it's not something like memory or video card that you will need to upgrade regularly.

    If you have to replace it, I recommend either Thermaltake or Enermax. I've have models from both companies and they are still running strong.
  12. +1

    Its something that if you cheap out on, can cost you more money :(

    I recommend Akasa, thier PaxPower PSU i have has been solid for the last few years.

    Sorry, I have to disagree. TT is not a good brand, even for
    PSUs, as they source from not-so-good OEMs, some even with
    dodgy reliability (like SirTec).
    Enermax is so-so, not too good, but not bad either.

    What I'd recommend is:
    Seasonic (excellent PSUs, I have one myself; also, very quiet)
    Corsair (made by Seasonic)
    Zippy (excellent, but also expensive and rare)
    PC Power & Cooling (same as above; recently bought by OCZ)
    FSP/Fortron Sparkle (good PSUs)
    Zalman (FSP)

    Antec and OCZ also have some series made by Seasonic and
    FSP, which are very good, but others are made by worse
    companies, and have higher failure rates, noise, lower efficiency,

    For fan reviews, look up spcr/silentpcreview or jonnyguru, who
    also has very good in-depth and critical tests.

    ^ that guy knows what hes talking about. Do not buy a thermaltake PSU.

    There is nothing wrong with Thermaltake. And the fact that you recommended an Antec, well I just find that funny, because my PSU that was making the whining noise and died on me was an Antec. No brand is infallible, but I've had my best of luck with Thermaltake though.

    I do agree on OCZ/Corsair/Zalman, also good brands.

    *shrug* ok. But they seem to get decent reviews plus I've owned different brands from both companies and never had a problem. In my experience they have been reliable. I haven't bought one in about a year or so, so maybe their quality has dropped off. Or, maybe I've just been lucky, but it's not like they are a no-name brand. I'm not saying they are top of the line, I'm saying I've found them to be reliable. If you are going to start overclocking, yeah, you might want to start worrying about exactly how clean the power is.

    Besides many of the brands you mention are going to be 25% to 50% more expensive for a similar unit. And while I do advocate buying a decent quality PSU, some people just can't justify $140 for one. IMO, for them a name brand like Enermax or Thermaltake is a good option.

    Another +1. I just put a Corsair PSU in the computer im building now. New graphics card and LED fans are in soon!

    Really offtopic here, But me and brother couldn't resist doing this. We took the heat sink of an old computer of ours that is utter junk. almost no ram, graphics suck, it lags and sucks, its a W98 BTW. So anyway, we took the heat sink off the processor and man does that think ever heat up faaaaaaaast. It was quite fun to watch it burst into flames and atch the computer burn. :hyper: :hyper:
