Newly built PC crashes during games and stress tests
Hello,
**PC System Specs:**
**OS**: Windows 10 Home 64-bit 10.0,Build 19042
**CPU**: Ryzen 5 5600x
**BIOS Version**: Amerian Megatrends Inc. L1.35
**Motherboard:** Asrock B550M-ITX/AC
**Memory**: Crucial Ballistix 16GB RAM DDR4-3600
**GPU**: Zotac Twin OC Edge RTX 3070
**Storage**: Samsung SSD 970 EVO Plus 1TB
**PSU**: Corsair SF600
**Problem**
I recently built a new computer and upon gaming, my pc will randomly restart. The issues were on and off for the whole month. At first, I suspected a faulty PSU from Silverstone, sfx 650w. Upon checking windows event viewer I was only seeing 6008 critical errors. Upon switching to a Corsair SF600 PSU, my pc also started rebooting again during games.
Another error before running tests was that I found that my pcie power connectors were loose in my GPU. After rectifying the problem, I still landed into issues of a full reboot.
I have run memtest to check RAM, I have done tests with HWinfo + Prime95 + Furmark. I have also done tests with OCCT. During these tests, the pc reboots around the 7-10 minute mark on my HWinfo log. Upon checking my logs, I read temps sitting around 78C for my CPU, and my GPU hit 70 as its highest with Furmark, and around 50-60s in OCCT.
I am confused with whether or not I have a GPU,CPU,Motherboard, or PSU issue. My ram has not run into any errors. I have tried setting to auto, 3200, and 3600.
