PC black screening from turning on Fan in same roo

[coreystevens503]

So I've been dealing with this issue for a while now.  Some times when I turn on or off a high-voltage device "box fan or air purifier" in the same room as my Tower my PC will stop displaying through HDMI and become unresponsive. This forces me to power down the system. sometimes I even have to turn off the power supply to achieve a shut down. I am beginning to think that it may be my power supply but I am not sure and do not wish to waste money if this is not the cause. It is worth noting that I purchased a EVGA 600 watt remanufactured power supply from Newegg. I am running a core I3 6100 with an RX 480 graphics card. Yes I know the graphics card is overkill. I got the CPU and motherboard on sale at Fry's for 130 just to get me going about six months ago. Anyway is there anyone out there with a idea why this might be happening. I'm suspecting and under voltage. Would buying a better power supply rated more than just a 80 plus white solve this?? Is my remanufactured potentially a dud? I would love to hear what you guys have to say. It is also worth noting that I have had this issue now in two different houses.

That sounds like the circuitry in the room (or building) is not good. I wouldn't think that something like the PSU would do that. Do the lights dim in the room at any time (when a high current device such as a fan is turned on without your computer on) when doing anything?

This sounds like a house wiring issue. While turning on a power heavy device can effect the power in the rest of the room (ie when I turn a powersaw on the lights dim briefly) it shouldn't effect a pc enough to cause it to crash.

I thought so at first too but I just moved and I am having the same issue at the new place? I think it is highly unlikely.

I originally thought that this might be happening but I have just moved from my old house to another and I'm still having this problem.
