Question Why do my monitors go black/lose signal when my GPU is under heavy load?

[joe_rigby99]

Hello, I've recently upgraded my PC from a 3080ti & 750W PSU to a ASUS TUF 3090 & a 1000W Gold PSU.

I mainly use my GPU for working in 3D and rendering. Ever since I upgraded and I start rendering a project, I come back to find that the monitors have gone black and when I turn them back on they just say 'no signal'. I have to hold down the power button on the PC to turn it off and then turn it back on again and the monitors come back on. I'm pretty sure it stays rendering while the monitors are off as the GPU fans can be heard still on a high RPM.

My PC Specs are:

CPU: AMD Ryzen 5 5600X 6-Core Processor
RAM: 64.0 GB
GPU: ASUS TUF RTX 3090
PSU: Corsair RM1000e Gold (1000W)
Motherboard: MSI MPG B550 GAMING PLUS

Hey there,

Is it consistenly at load?

Have you changed cables/ports?

Have you tried uninstalling the GPU driver with DDU, and reinstalling fresh?

Are all system drivers up to date, including chipset?

What bios are you running on the mobo?

Is the 3090 new or second hand?
