Hi everyone, just joined to hopefully get more experienced people to look on my case. Last month I bought a new computer (all the parts) and built it myself. I began quickly to notice that my computer suddenly would reboot on its own without any warning. This only happens in a small selection of games such as Minecraft and Runescape 3. Sometimes it happen right away or maybe an hour or two. However, the driver has crashed in for example Overwatch. I cannot remember if it has rebooted on Youtube use etc.
What I have tried/speculations:
I appreciate all suggestions and help! Thanks!
EDIT: I forgot to mention that when the reboot happens my DisplayPort monitor turns back and my HDMI monitor turns green for a split second. Additional, all the cables are connected to only one outlet (power supply, two monitors, surround sound (usually off when playing) and a small fan).
What I have tried/speculations:
- Different drivers (2019 versions and 2020 versions)
- MemTest86 for three hours to test RAM, passed three tests with no errors
- Prime95 for a couple of mins, no reboot
- Heaven Benchmark for a couple of mins, no reboot
- Swapped the PSU from my older PC, the Corsair CX750M
- I could play runescape for 5-6 hours yesterday and thought that was the problem. This morning it happen 15 mins in Runescape.
- Swapped the GPU with a nvidia 970, nothing happen for an hour, but it does not use same amount of power.
- Boosted the computer from the power button, no power/light in keyboard or mouse
- CPU: AMD Ryzen 3900x
- RAM: G.Skill TridentZ Neo 32GB CL16 16-19-19-39 (I think they sent the wrong one, so I got 16-16-16-36)
- GPU: AMD Radeon 5700 XT Red Devil
- PSU: Corsair RM750x (2018)
- MOBO: Asus ROG STRIX X570-E
- CASE: Lian Li O11 Dynamic
- FANS: 3x Noctua NF-12F & 2x Noctua NF-S12A
- AIO: Deepcool Castle 360 RGB v2
