I unplugged the HDD and the noise continues. So it's probably GPU coil whine. It gets very annoying at times but at least it isn't harmful. Thank you for the help!

I could try disconneting the HDD. The noise really doesn't seem to be coming from the HDD though and is only really present during intense VRAM usage and not HDD usage. The GPU has been ripped out of a HP prebuilt PC, seems like this exact model I found on Google.

The only fans are inside my pc and therefore I can't really turn them off. Specs: CPU: Intel Core i5-9400F GPU: NVIDIA GeForce RTX 2060 PSU: CORSAIR PSU CX600 600W RAM: 2xSamsung M378A1K43CB2-CTD Mobo: ASRock Z390 Pro4 1xNVME SSD, 1xHDD, 1xSATA SSD (Please inform me if further details are needed)

Here is the unedited audio. It is pretty quiet and the fans drown out a lot of the noise though.

Thanks for the reply! I did a bit more testing and figured that the sound increases specifically the more intensly the VRAM is used. Is this possible? And if this is coil whine, it is normal and to be expected, not harmful and nothing can be done, right?

Recording of the noise, edited to be as noticeable as possible. Notice the kind of rhythmic noises behind the ambient fan noise. Could this be coil whine, maybe a faulty fan? I am not sure. None of the fans seem to be hitting anything. I suspect from listening that the noise might be coming from the graphics card. This is also suggested by the fact that the noise is more noticeable the more load is on the GPU. The noise is pretty loud and noticeable IRL but it was difficult to record. This has been going on for some weeks(?) and I don't remember hearing this noise before that. What could be causing this? Should I be worried? Thank you in advance!!

Ok I solved it. I had misinterpreted the motherboard manual and had the CMOS reset jumper on reset instead of normal operation.

Tried both VGA and HDMI (with a HDMI to VGA adapter), no display from either.

Which one? The display cable is confirmed working with another PC.

I am positive. According to AMD's website it specifically has AMD Radeon™ HD 7560D graphics.

The PC has no display output but there are no buzzer error codes and the fans, the HDD and the front panel power LED turn on. I am running on integrated graphics. Is this a PSU issue, maybe too little wattage or something? Specs: 350W Acbel hba005-za1gt 350W PSU Asus A88XM-A Mobo AMD A8-5600K APU Kingston 99U5584-012.A00LF 4GB RAM

Fixed it! Reseated the CPU and RAM once more and plugged in the HDMI cable! I had accidentally removed it when reseating the GPU. Massive facepalm... Well, I'm glad there isn't a hardware problem.

Update: Got my hands on an internal speaker and the error code is three beeps and a long pause. Then it starts over again.
