Test Server Causing my PC to completely shut down. Is this a known issue and is there a fix?

As the title states, whenever I try to play on the test server, my pc completely shuts down. It has done it at different stages, once at the main menu, a few times I n the pre-match warmup, and on the loading screen when entering the game.

I was able to launch the test server two days ago prior to the recent ~2GB patch and it was laggy, but did not completely crash my pc.

A little background, I have been able to play the early access version fine with really no issues and less than a dozen crashes throughout my entire playtime. I have 346hrs recorded on the standard PUBG servers at this time.

PC Specs:

i3 7100 RX480 8GB 16GB Ballistix 2400 RAM 250GB SSD 1TB HDD

Yes I know this is on the lower end of specs, and I typically run on low settings which is fine for me. I have been able to get above 60FPS consistently (usually 70-90) on the early access servers with no issues.

I am just curious if this is a known issue or if anyone knows of a fix? I'm assuming it's maxing out the CPU but I haven't ran an overlay yet to see what it's doing before the crash.

Any helpful insight would be great. Otherwise I suppose I'll wait for the full release and hope it gets better!
