Parts: Ryzen 1600 MSI B350 Tomahawk Thermaltake Toughpower 750w 8gb Corsair LPX So about 4 weeks ago, my pc just died. It wouldn't come on, MOBO lights showed DRAM and CPU issues. The RAM was new, so I rmaed the CPU. I got the new CPU and the same lights come on and my pc won't start. So I ordered a new MOBO (Gigabyte Gaming-3) and that doesn't work either (CPU light stays on). I'm kind of at a loss for why It's not working at this point. I've tried a different PSU, RAM, HDD, GPU, putting the pc together outside the case, and running with only essentials. Nothing seems to work. I've never had issues like this with other PCs I've build, all of them besides this one have been running fine for years, this is the only PC I've ever had to do an RMA for also (3 of them).

Specs: Ryzen 5 1600 MSI b350 Tomahawk Corsair Vengance LPX 3000mhz Sapphire RX 560 2GB Thermaltake 750w 80+ Gold Hitachi Deskstar 2tb 7200rpm I've had this PC for ten months, but have already had three hardware failures. The first was a day after I built it, I had finished stress testing and was doing downloads when it shut off and it turned out the CPU was dead. I got an RMA, and haven't had another issue up until a little over a week ago. I started getting frequent BSODs, and found a RAM stick had failed. I got the replacement, and was running fine for a few days till I turned on my PC in the morning and it shut off on the windows login screen. The EZ dubug CPU light turns on when I turn my PC on, after a second the DRAM light turns on too. I've tried basically everything, including another PSU, and narrowed down the dead part to either the Mobo or CPU. My main issue is that I don't think the amount of hardware failures I've had is normal, and I'm worried my Mobo or PSU is ruining parts. Did I just get unlucky?

I'm still using the iGPU of the A-10 7850k.
