Hello, all. I am at my wit's end trying to get my system to work. I did my first build from scratch in September, and I've had issues with it from day 1. I've resolved display issues and boot issues, but I still can't figure out the last one. My computer will randomly shut off anywhere from a few minutes to a few hours after start up, usually ~1hr. Usually, it's not under heavy load when it restarts. All current components have been bought new since the beginning of September. My build is:
Ryzen 5 1500x
Gigabyte Aorus RX 580 xtr
Asus x370 prime pro
G.Skill FlareX 16GB (2x8) 3200 running at 2400
WD Black 512GB M.2
EVGA Supernova G2 750W
HAF X full tower
The issue has persisted throughout all my troubleshooting.
My first MOBO was a Gigabyte gaming K3. I had 16GB of G.Skill Ripjaws V 2666 originally, and have tried each of the four sticks individually. I RMA'd my first 1500x and AMD sent a new one. I RMA'd my RX 580 to Gigabyte and they said it showed no issues and sent it back, and I've put a 1050Ti in to see if that would work, and the issue remains. The first case I had it in was an old Thermaltake. I tried an OLD (10 years) 500W power supply with it and had the same issue. I finally took it in to a shop and they couldn't figure it out either.
I've run furmark plenty of times to see if I could induce it with heavy load to no avail. Here are the results:
RX 580 running 1440p GPU stress test
1050Ti running 1080p GPU stress test
The last time it shut off with the 1050Ti in, it went to the "x # of programs still need to close" and I was able to click cancel to keep it from shutting down, but programs had been closed. This seems similar to me to this thread: Ryzen 1700x New build shuts down randomly but the new EVGA PSU makes me think it's unlikely to be the problem? Is there anything anyone can think of to help me diagnose this?
Thank you very much for any help you can give.
