Hey everyone 
I just made this build for a friend of mine and for some reason this system would restart of ~5-10 minutes of gaming or 1-2 minutes of stress testing.
My guess: Temperature / Power / Drivers / Hardware
What I have done so far:

I just made this build for a friend of mine and for some reason this system would restart of ~5-10 minutes of gaming or 1-2 minutes of stress testing.
My guess: Temperature / Power / Drivers / Hardware
What I have done so far:
- Temp: FurMark CPU stress testing goes well, highest CPU temp after 10 mins of testing is ~73°C ~74°C
- Temp: FurMark GPU stress testing initiates a restart within 1-2 minutes. The restart happens almost immediately when the GPU reaches ~72°C. Last info I see from FullMark GPU stress testing is ~72°C GPU temp and 70% fan RPM capacity.
- Power: 550 Watt 80+ power supply shouldn't be an issue I guess coz everything is running at stock. However, I am not ruling out the possibility of insufficient power.
- Drivers: Drivers were downloaded via IObit Driver installer initially. I have also tried downloading & installing drivers manually via AMD's website.
- Hardware: I suspect GPU was plugged in before. Relevant Reddit post. GPU BIOS version: 015.050.002.001.000000. A quick check on techpowerup.com indicated the BIOS is stock.
- BIOS: BIOS was already updated to latest 1607 version out of the box.
The system sends no data to monitor and turn blank screen. The system freezes (numlock not responding) for a while before I have to forcefully restart the system.
I couldn't find a way to look at BIOS logs to look for thermal trips. Is there such a feature in B450M-A ?
I hope I have a lead and it's just a bad GPU and not bad config. I am freaking out as I have previously build 5-6 low spec systems and never encountered any issue. This my first gaming build and it's not going as planned. I really need some help 🙁
