Hello,
I've had my computer for about three years now. It was self-assembled, and barring a few hiccoughs, has worked rather well. The other day, however, the computer began to emit a harsh buzz in short burst of half a second to one second. It does this irregularly, sometimes only a few minutes between buzzing, sometimes going for hours without making a sound. It sounds like the noise a fly makes when it's stuck against something, buzzing to escape.
My PSU is a Cooler Master Silent Pro 1000w. Honestly, I don't think I needed 1000w, I got overeager when building my computer. Since this started, I've unplugged everything, cleaned my computer, checked the parts, moved around all the wires, done just about everything I can without pulling apart the power supply.
There are some strange elements to the buzzing. Firstly, it happens even when the computer is powered off entirely. The PSU is still plugged in to the wall socket, and it's still turned on, but the computer itself is off, as are all the fans. I don't know what to make of this.
Secondly, the buzzing - and I might be getting conspiratorial here - seems to happen only within a specific timeframe. Today and yesterday, when it first happened, the buzzing began at around 8:00am. After several hours, around 1pm, the buzzing ceased, and despite using the computer for the rest of the day, I didn't hear it again once. At 8:00am again today, cue buzzing.
Other than the buzzing, the computer works fine. It's making me uncomfortable, and the sound is incredibly irritating.
I'd like to know whether anything stands out as an obvious cause. I'm not entirely worried that this means the death of my PSU, since it's only intermittent. Should I download a program to monitor my voltage, and if so, what program would you recommend?
Thank you.
