Persistent problem, intermittent freezing or buzzing sounds.
Persistent problem, intermittent freezing or buzzing sounds.
Previously, my previous update addressed a similar problem. The suggestions were to replace the drivers and use a more robust power supply. The main concern was random freezing of the PC and unusual speaker sounds. I've tested various solutions so far: updating GPU drivers, switching to a higher-capacity PSU (from 500W to 750W), and limiting processor usage in Windows. Despite these efforts, the issue persists. My current setup includes an Intel I7-4790K with 4GB DDR3 RAM, a 1TB and 2TB hard drive, a DVD burner GTX 1060, and a Dell A03 motherboard. I also noticed two RAM sticks from Samsung and two from Micron; their speeds differ slightly from the expected 1600MHz, and they're running in dual channel. Could this configuration be contributing to the problem? Any additional tips would be appreciated.
It might relate to two separate matters. Identifying the source of the noise could help a lot. A field serviceable stethoscope or ear horn—perhaps rolled up into a paper roll—might offer enough clues to locate it. It could be a fan (unlikely) or a PSU or another part (likely) if the spot is known, which would speed things up.
P.S. That handle makes me think about when Twiggy passed away. It was some time ago. She was the first really skinny supermodel. Edited July 27, 2022 by Bombastinator
Audio noise from speakers may stem from software issues, hardware faults, or electromagnetic interference from inside or outside the enclosure, or even physical speaker damage. Faulty speakers often produce buzzing sounds.
When discussing EMI, my Wi-Fi performance here is very poor, and I rely on Ethernet via a Wi-Fi bridge. Perhaps I should take out the Wi-Fi module from the case and check. Are there other sources of electromagnetic interference? It’s not speaker damage—speakers function normally, and volume reduction makes the environment quieter.
Variety of items including those outside your home appear regularly. The drop-off is strong across distances, meaning objects farther away must generate a significant amount. Old electric motors were well-known for this effect. (Modern motors need shielding to avoid it) Thus, even an old air conditioner, refrigerator, or vacuum can achieve it. A device like an arc welder might be capable; large ones are frequently prohibited in residential zones due to the issue. Inside, it could be as simple as two insulated wires intersecting at the wrong angle and position.
I question using the wifi card will make any difference—it’s harmless. It might also stem from a software problem. The key is eliminating variables; none of these actions cause harm or expense. What type of speaker are we talking about? Certain models don’t produce sound. Edited July 27, 2022 by Bombastinator
they're the audio devices on my TV that I use for monitoring. They function properly with other systems like Ninetendos, PS4, PS3, etc., so the ones I'm familiar with remain intact. The buzzing occurs specifically during freezes; otherwise, both the PC and speakers operate normally, confirming it's not the speakers themselves.
It seems the issue likely stems from something intermittent rather than EMI in your case. Movement without cause could point to software glitches or external forces like appliances or devices. Checking the circuit for other loads might help. Observe timing patterns—does the problem align with household activities? Appliances such as refrigerators or ACs switch on/off based on thermostats, making their behavior appear erratic. If wiring isolation resolves it, that could be the solution. A UPS might offer some insight but isn’t certain. Let me know if you’d like more details.
