    Extremely Loud Screeching coming from the PSU


    Apart from my Thread_Stuck_In_Device_Driver BSODs and completely broken Windows Apps, I have recently stumbled across a new, very unnerving problem, that has so far only occured twice. I was playing Counter Strike: Global Offensive for about 3 hours, before my computer started making a rumbling-buzzing noise. I have looked at my computer and while I was looking at it, the rumbling turned into a really loud high-pitched screech, so loud you could hear it downstairs. This literally scared the living dumplings out of me, and I rushed to unplug the power cable. Now, if I didn't reconnect to the Counter Strike match within 3 minutes I would be banned for the next 7 days, so I decided to power up the machine. The screech continued, so I unplugged the machine, and without taking much notice - opened by case (to pinpoint the sound). However due to the rush I have broken a ribbon on the side, meaning I have voided my guarantee (as stated on it, as I found out after).
    I ran the computer once more, and I could identify the location of the problem - the PSU was responsible for the screech (I intially thought it'd be the CPU fan). I left the computer open for a while, then after an hour I put it back together and the sound is nowhere to be seen. However the computer continues to hum (not a normal humming), so I placed a 500g object on top of where the PSU lay and the humming is gone. (Now I am also banned for 7 days in Counter Strike)
    The computer (and therefore PSU) is less than a month old, and due to the breakage of the ribbon I have lost the warranty.
    I will attach the DM Log here as it contains some information about my machine and my configuration.

    Well, I guess the good news is that you have 7 days to replace the PSU and do a clean install of Windows 10 build 10586. (you had outdated build 10240 on it before. I would make sure to capture the Windows 10 Product Key with showkeyplus from this forum, although it should be permanently stored in bios or on a COA sticker on the case.

    Honestly after the troubles with Windows 10 I may fallback to Windows 8 or even Windows 7 :)
    I currently have no money to pay for a new PSU

    I suggest that you check on the warranty anyway. In the US, it may not be legal to deny warranty support simply by putting a seal on the box. The laws may be different where you live.

    I suppose that the noise was due to a fan problem in the PSU. It may be simple to repair. Unfortunately, PSUs are notoriously dangerous to mess around with. For reasons I don't pretend to understand, they typically have internal voltages of hundred of volts present. How long such voltages might be present after being unplugged from the mains power, I can't guess. (In a poorly designed system, it could be hours.)

    Presumably, the box came with Win 10. How would you go back to an earlier OS? Do you have a spare 7 or 8 retail license lying around? If you are serious about that, I suggest that you check for driver availability before proceeding. (A Windows license costs more than a fairly good PSU.)

    I would agree with Bobkn, I would try the warranty anyway. Replacing the PSU is necessary in any case. It doesn't matter which OS you use, the PSU has to be fixed. It powers the whole system and Windows 10 had nothing to do with a hardware failure. The PSU is a no choice decision, no matter which OS you run.

    Better change that PSU BEFORE using computer any more, it can burn more components and make untold damage !!!!
    Problem with ready built systems is that they invariably put components of "just enough" quality and main reason I'd rather make my own. If your warranty is honored insist they put a better and stronger PSU in even if you have to pay extra.
