Hey guys,

< Last updated: 11/16 - SOLUTION FOUND >

A few months ago I purchased two identical computers from CyberPowerPC. Both machines have been having the same issue: as titled, while gaming, the display randomly disconnects. I can still hear my game running in the background, however, the screen is blacked out and displays a "No Signal" error. This issue has persisted in a variety of games and does not seem to have a specific scenario that causes it outside of it only occurring while gaming.

The only "fix" thus far is to force turn off the system and then boot it back up. After gaming for a bit, the issue resurfaces. Again, the biggest factor that baffles me with this problem is that it happens to BOTH machines as opposed to being an isolated issue. This suggests to me that there is a fault in the hardware or the distributor's build process. I have reached out to CyberPowerPC over a week ago now and am still awaiting their feedback.

My troubleshooting attempts thus far (with no success):
  • Plugged in a completely different monitor after the issue occurred while the computer is still running; same "No Signal" error showing on the monitor. This to me indicates that it's an issue with the computer and not the monitor nor Display Port cable.
  • Updated (11/12): Changed out which monitor cable port is being used. Tried using an HDMI cable instead of the current Display Port.
  • Completely uninstalled graphics drivers (and GeForce Experience) and then performed a clean install.
  • Updated 11/12): Ensured all internal hardware and cable connections (including the PCIe ones) are secure
  • Checked GPU temperature right after rebooting following the issue. Temperatures all within normal ranges. The issue also seems to occur at varying temperatures so it doesn't seem to be related to an overheating scenario.
  • Pending (11/12): CyberPowerPC has offered to send replacement GPUs (about 2 weeks to arrive)...
THE SOLUTION: (Added 11/16)
  • Replaced the Standard 80 Plus Gold PSU with an 80 Plus Platinum Certified PSU on both machines. After several days of testing, the issue has not resurfaced. Thanks rgd1101 for your input!
My systems (both identical):
  • MOBO: MSI MPG Z490M Gaming Edge Wifi 6, Micro ATX, ARGB, Intel 2.5GbE LAN, 2 PCIe x16, 4 PCIe x1, 6 SATA3, 2x M.2 SATA/PCIe
  • GPU: Nvidia GeForce RTX 3070 X TRIO 8GB GDDR6 (water cooled, not overclocked)
  • CPU: Intel Core i9-10850K 10/20 @ 3.60GHz
  • RAM: 32 GB
  • HHD 1: 1TB Samsung 980 Pro NVMe M.2 SSD
  • HHD 2: 1TB WD Blue Series SATA-III 6 GB/s SSD
  • PSU: 1,000 Watts - Standard 80 Plus Gold Power Supply
  • OS: Windows 10 64-bit
Thanks!

so a generic psu? replace it.
Forgive my naivety here but if the PSU is causing the GPU to crash (I'm guessing that's what you're getting at), wouldn't my games crash too? When the issue occurs, I can still hear my games running in the background and reacting to my keyboard/mouse inputs.
