I've encountered a really frustrating problem with my GPU and I need some advice. My setup is as follows: I have an AMD Ryzen 9 9950X3D CPU, an NVIDIA RTX 5070 Ti GPU, an MSI X870E-P motherboard, and I'm running Windows 11 on a dual monitor setup (one main and a smaller 8.8-inch LCD). Everything was running perfectly until I let my PC sleep for two days straight. After turning it back on, games now seem to only use the integrated graphics, which is causing crashes due to memory issues. I've tried several troubleshooting steps, including restarting, reinstalling NVIDIA drivers, disabling integrated graphics in BIOS, and using Display Driver Uninstaller to clean my GPU drivers before reinstalling them. The GPU shows up in Device Manager, but games either default to integrated graphics or don't recognize the dedicated GPU at all. I'm looking for any advice on how to resolve this issue!

Sounds like your issue is almost solved! I had success once by simply letting my PC sit powered off for a few hours with the plug removed. It seems odd, but it reset things for me.
Are both your monitors connected to the GPU? It’s crucial that the main display is plugged into the dedicated GPU rather than the motherboard. Make sure to double-check that.
Ensure your power settings are on 'High Performance' instead of 'Power Saving'. Power Saving can default to using the integrated GPU. You can also manage which GPU should be used for each application in the graphics settings.
I also had similar problems after my PC went into sleep mode. I just disabled sleep/hibernation entirely and turned off the monitor instead. That fixed my issues completely!
Consider doing a CMOS reset and ensuring your BIOS is fully updated. Sometimes a simple reset can fix recognition issues. Also, check that all power connections to your GPU are secured without any gaps.
Yeah, one monitor is connected to the motherboard using USB, while the main one is on the GPU. It's been fine until the sleep mode mishap.
