Dell XPS 8910 Desktop computer
- Intel i7-6700 CPU
- 16GB DDR4
- 1TB HDD
- Nvidia GeForce GTX 750Ti 2GB GDDR5
- Windows 10
- 370W Power Supply
Brand new dell computer I purchased. I hooked it up in my bedroom. It keeps rebooting automatically around 5-15 mins after logging into windows 10. At first I thought it was an overheating issue with the cpu and maybe the cpu fan isn't working causing the failsafe reboots. But checked the fan and it's working. And then I realized the power supply fan isn't spinning when the computer is on. So maybe it was from a bad psu? I notice it might be the psu fan not spinning because it isn't under load. But then even when I first turn on the computer, the psu fan doesn't spin. So maybe it is due to the psu fan not being able to work in higher loads causing the computer to reboot. It is usually also very laggy in the os, especially before it is about to reboot.
I then hook it up to living room downstairs where it is only connected to the monitor and keyboard/mouse and the rebooting issue disappears. It doesn't reboot itself like it does upstairs. While upstairs in my bedroom, it is hooked up also to an ethernet cable and a speaker system with an amp (lower power wattage though). The lag still there, but not as bad as when I hook the desktop computer upstairs in my room.
So beginning to wonder if it is possible psu related and not being able to have enough power cause those reboots. My psu is 370w. Unless the addition of the lower power speaker and amp draws that much more power.
It is under warranty and still in customer support service. So I could easily have home support come look at it. But I just want to get an idea of what the possible issue is before calling for support to come look at it, in avoid having the issue not appear when they come in and say the machine is fine. I want to be able to hopefully trigger the problem when I do. I also want to avoid tinkering too much myself in fear it would void the warranty.
Thank you in advance.
