PC Crashes under stress at home, works fine at a local computer shop?

Specs:

  • i3 6100
    ASUS R9 380X
    Corsair VS550 PSU
    ASUS B150M-A-D3 mobo
    2 sticks of 8GB RAM
    Windows 10 Pro x64
    ASUS VX239H Monitor
Problem:

Whenever the computer is under stress, it reboots and shows the ASUS Anti-Surge protection screen saying that a surge was detected and Anti-Surge was triggered. I thought it's probably a PSU or a GPU thing and went to a local computer shop. Now, at my house whenever I ran FurMark stress test or Mass Effect Andromeda, my computer rebooted and that ASUS screen appeared. It reboots during the inital Mass Effect: Andromeda load screen and whenever the stress test is started.

Here's the fun part. At the shop, we ran FurMark stress test and Mass Effect Andromeda simultaneously. It f'ing worked. I have no idea what is happening.

I have tried a new PSU, a new PSU power cable (since it was the only thing different we used at the shop), disconnecting the UPS, trying different rooms of my house, different outlets and sockets, different powerboards. Interestingly, Dragon Age: Inquisition ran fine which has the same engine as the new Mass Effect. So far I've only had this problem on Warframe, and Mass Effect: Andromeda. League of Legends runs fine with no reboots.

I went ahead and disabled ASUS Anti-Surge, which resulted in less frequent reboots. But now whenever the computer comes under stress (i.e. when playing heavy games) it freezes and shows HDMI No Signal screen. I figured out that the PC was frozen by playing a song in the background before the No Signal screen. The song just froze and the sound kept coming.

I'm thinking something is up with my HDMI cable? It's the only other thing that is different here from the shop. I used this very HDMI cable when checking in different rooms of my house. This is not the one that we used in the shop so I'm thinking that this is it but it seems very unlikely. Also, I have monitored CPU and GPU temps both while idle and while under stress. They seem to be fine.

I've tried reinstalling drivers multiple times so you can tick that off. Any other suggestions?

There is no dust inside the PC, I made sure of that. I have it sitting on top of my desk, it has a pretty good airflow I'd say.

I have tried connecting it directly into the wall, into the UPS, in multiple power strips but the issue still persists.

I have checked all the cables inside the computer and made sure that they are properly connected. I am really at a loss here... sometimes I think my graphics card is going bad, RAM is going bad but then I remember that this very PC works very well at the shop and that thought just throws all the ideas I have out the window.

If you guys could help, it would really mean a lot to me. I built this PC by saving for 2 years, it's not even a year old. It is really frustrating when something like this happens.

Thanks.
