As the title suggests, my PC has been freezing in games lately and comes with this buzzing noise from the speakers. After a few seconds, the PC would restart itself and would boot into windows. However, this happened again last night but the difference is that now my PC won't even boot into windows and my monitor says no signal on it. None of the USB peripherals such as the keyboard or mouse light up, but my graphics card is working (know this through fans spinning) and cpu is working as well as all the motherboard lights being functional.

Any help would be really appreciated as I am at a loose end trying to figure out what has happened?

I gave my advice:

1. shut down and confirm memory (and all power connectors) are fully seated.
2. swap PSU
3. swap graphics card
4. swap motherboard

I'd guess the memory sticks first, motherboard second, third is PSU, and graphics card last.

I'm not sure what kind of buzzing you got with the audio so that could be a bad voltage signal (PSU), or CPU having issues (system memory, or even video card).

You can get WEIRD issues but at some point you just have to start swapping based on COST and EASE.

You haven't proved the CPU and graphics card actually work properly.

At this stage it's swapping out HARDWARE in the logical order.

If you have an iGPU (i.e. Intel CPU) and can get video without a sound card I'd first shut down and remove the video card, then connect the monitor to the motherboard.

Or swap to any video card you know works.

I'd next be suspecting the MOTHERBOARD or POWER SUPPLY.

Motherboard is a hassle. If you can buy a cheap PSU (or if you have one now's a good time for a quality one as an investment) or borrow one.

Any PSU that works and provides at least 250W should be plenty for bootup (even 100W but I don't think you'd even find one).

I do doubt it's the graphics card due to the audio problems. PSU could work partially, but based on my experience it's not my top choice.

I think my top choice would be the MOTHERBOARD but again it's a hassle so best to swap OTHER parts.

*I'm not sure if LOOSE SYSTEM MEMORY (DDR3/4 ram sticks) can cause these issues or not. Make sure they are fully seated when the PC is off.
