Same here... It's driving me crazy. Some days the PC is totally fine and some others the PC freezes, very most of the time while gaming.
What happens in my case is that the lights of my fans switch back to their default color (which, in my case, is rainbow type with some effects), and 5 to 10 seconds later, the PC freezes completely and I need to hard reboot it.
I have suspected each of my components and ran countless tests, until I had to start suspecting iCue and I was not even imagining such a dumb piece of software be able to generate such mess...
I just removed it after finding this thread, I hope I can find some peace.
My config:
12-Core AMD Ryzen 9 3900X, 4342 MHz (43.5 x 100)
Asus ROG Crosshair VIII Formula
Corsair Vengeance RGB Pro 4 x 8 Go DDR4-3200 DDR4 SDRAM
NVIDIA GeForce RTX 4070 Ti (12282 Mo)
