Hello.
As indicated in the title, the problems occur in the same way with both of the graphics cards I own (MSX GeForce RTX 3090 24GB and Asus GeForce RTX TUF Gaming 3090 24GB) and are as follows:
1) Sometimes I have to restart three times for the system to recognise the GPU. In these cases, when I restart for the second time, and until I restart for the third time, the GPU fans run at maximum speed.
2) When the operating system starts up and the GPU is detected, after a while, the connection to the GPU is lost and I inevitably have to restart (I haven’t measured this time and I don’t know if it’s always the same, but it’s around 10 minutes).
The internal graphics card is always working. The Nvidia drivers and BIOS are updated to the latest version.
I don’t know if I need to change something in the BIOS or if there are problems with the Esata. Any suggestions are welcome.
