My PC keeps hanging by going to a black screen and sending no signal to the monitor. It is my daily use PC. I have a box fan plugged in to the adjacent wall's receptacle. I just now noticed that I can change the speed on the box fan and it will immediately trigger System 2 to hang like it has been doing about once a day randomly for the past 2 weeks (since I installed the new (refurbished) motherboard) which I suspected to be the issue and I've already ordered a replacement.

What could be the issue here?

That being said, dirty power can definitely cause these sorts of issues. A line conditioner will likely solve your issue, but I'd recommend getting a UPS because of its more capable surge protection features.

Unfortunately, these sorts of power management products are out of my niche. I don't really know enough about them to recommend a make or model.

I could think of a few issues.

When you turn the box fan down, the system hangs? Likely a heat issue.

Unless your motherboard is making a buttload of heat, it's likely not the issue here.

Full system specs please. What CPU cooler are you using? Is the fan on the CPU cooler actually spinning when the system is running? Make and model of power supply?

Okay. I used an extension chord to plug the PC in to another room in the house, and the issue is not happening when I change the fan speed. After reading some other posts, I think it's noise in the electrical lines. It's a rather old house and I already have a GPU mining system with 4 GPUs (uses 570W) running in the same room, but it doesn't have any issues.

Full system specs:
Pentium G4560
CRYORIG H7
MSI Z270M MORTAR
8GB Corsair DDR4 2400 LPX CL14
Kingston HyperX Savage 240GB
XFX RX 470 4GB
EVGA 500B
2x CRYORIG 120mm intake fans
2x 120mm exhaust fans

No heat issues.

Good quality parts. I doubt it's a faulty part playing with you.

"No heat issues." What is the CPU temperature when sitting at the desktop? What is the CPU temperatures when stressing the system (gaming, benchmarking, etc)?

CoreTemp is my recommendation for monitoring CPU temperature in Intel systems. http://www.alcpu.com/CoreTemp/
