Question Force restart then no video output

[Jord1920]

I've recently built a new PC with a fresh install of Windows 10 (Ver. 20H2). Twice this has happened where I'll be 2-3 hours of continual use (Gaming, watching videos etc) and it'll act as if someone has pressed the Reset button. It'll immediately turn off and attempt to reboot. I don't get any erorrs in event viewer, no BSOD, just straight to a black screen. However, the RGB in the system doesn't turn off (RGB RAM, AIO, FANS, and the lighting on the GPU).

When the system attempts to boot back into Windows, there's no video output on the monitor. I have tried unplugging and replugging the monitors in, however this doesn't help the situation. I know that the PC has successfully rebooted however as I use a RDP tool on my mobile phone, and I'm still able to get onto the machine. I attempted to open Device Manager to see if the video card had been recognised at all, however it wasn't appearing. AMD driver software didn't recognise a GPU installed at all.

The only way I can get a video output (I've found so far) is to turn the machine back off, pull the power cable out and clear the residual power by holding the power button for 15-20 seconds. I can then replace the power cable and it seems to boot fine.

I've found that the BIOS hasn't reset (XMP profiles on the RAM are still set), and as mentioned before I cannot see any errors in Event viewer. I've been able to run benchmarks on the machine and it seems to be performing correctly. Also I've recently used the Display Driver uninstaller as well and ensure that a recommened version of the GPU driver is installed. I've ran sfc /scannow within windows and all files verified successfully.

The first time this happened I wasn't sure what to do, however when this has happened today I have reseated the GPU, RAM and cleared the CMOS. Can anyone suggest any fixes, or potential culprits?

Welcome to the forums, newcomer!

Why does that screenshot look like you're using a third party app to update/install your drivers? If so, you're advised to install any and/or all drivers in an elevated command, i.e, Right click installer>Run as Administrator. Source all drivers except the GPU drivers from your motherboard manufacturer's support site. Since you own an AMD card, the latest driver from AMD is in order.

What BIOS version are you currently on? How old is the PSU in your build? The issue you explain seems like the PSU might be unable to power the entire system when taxed. Did you create the bootable USB installer using Windows Media Creation Tools? Use HWMonitor to monitor your temps when the issue crops up.

Sorry for the screenshot it problably doesn't show everything you need to see. The app is the Armoury Crate software that is prompted after installing windows 10 https://rog.asus.com/us/innovation/armoury_crate/

The BIOS version is 1805. I've seen on some forums that people suggest not using the most recent bios versions and sometimes using an older, more stable version. Could this be a factor? I installed windows using the Media Creation Tool from Microsoft's website, booting to the USB stick, then installed relevant drivers etc that were prompted, and then installing the GPU drivers from the AMD website via the Radeon software.

The PSU is brand new along with the other parts in the system.

UPDATE: Just seen that two new bios udpates have been released. I will attempt a bios update to the recommened version, not the beta version.
