Question Monitor blacked out while playing Hitman 2

[Dcopymope]

Here are my specs:

1. Motherboard: HP 500-267C
2. Windows 10
3. AMD RX 470 4 GB
4. Intel I7-4790K
5. PSU: 500 Watts
6. 16 GBs of Ram
7. Samsung SSD 860 QVO 2TB

I just got the damn thing back from Best Buy a few days ago. They installed an anti virus software called 'Web Root' and I just uninstalled it with the assumption that it could be the cause. I have tried everything. I even replaced the damn thermal paste on both the CPU and GPU. The only thing I haven't done was do a clean install of Windows 10, which I have no interest in doing whatsoever, not for this piece of detritus computer. Could this be a power supply issue, or could it have been Web Root? It didn't look like heat was the issue, as both processors maintained a temperature no higher than 70 on average.

Just replaced my HDMI cable with a new one, so I'll see if that solves the issue, give it about a month or so I guess.

My monitor blacked out twice with some of the settings set to high in Hitman 2. And yet, it suddenly hasn't done it ever since I turned down a few of those settings. What gives? Am I asking for a little too much from my RX 470 when I set the graphics settings too high or what? Mind you, this is a very demanding game compared to Hitman 2016. It does reccomend an 8 GB RX Vega 56 afterall.

Which PSU do you have?

No, settings won't cause a no display situation.
At lower settings, the card may well be drawing less power, which may be the reasoning.

So its drawing less power at lower settings, yet that somehow has nothing to do with it? I have an Inland PSU, 500 watts I recall. The model number is 14025SL, if that matters at all. The technicians at Best Buy claimed my issue was not hardware related. They thought that it might have been a software issue, either the anti-virus software they installed or the operating system, and they may have to do a clean install if the problem is the latter. They didn't do a clean install of the operating system but I have uninstalled what is now the second anti-virus software they put on it in place of malwarebytes. So far, the screen has only blacked out with Hitman 2.
