"Out of memory" alerts and crash to desktop soon after starting FSX-SE.

I have a brand new computer from XForce PC with Win 11 and I am running FSX-SE.
    Intel Core Ultra 9 285K (3.70 GHz)
    32 GB RAM
    Nvidia GeForce RTX 5070 (12GB)
    2TB SSD
    64 bit system and processor
I also have the following equipment in my home cockpit;
    Saitek/Logitek - Yoke and rudder pedals, radio panel, switch panel, multi panel, trim wheel,        Cessna TPM.
    Desk Top Aviator - Parking brake and Fuel selector.
    Home built - Garmin GNS400 interfaced via an Arduino Mega and Mobiflight connector.
    I have paid versions of FSUIPC and SpadNext and a 4 monitor setup.
Here's the problem. I can't go flying because by the time I get my views arranged and do a preflight and taxi out I start to get "Low memory alerts" and then crash to the desk top. I've reduced my sliders half way with no change and eliminated everything in the background that I know of. My old AlienWare never did that. I don't know what else I need to do. Anybody have any suggestions?
