HP Elitedesk 800 G3 SFF with RTX 5060 LP switches to integrated GPU when rebooting

[Motongo]

Hey Guys,

I recently upgraded to an RTX 5060 LP and 500w PSU. Previously I used a GTX 1650 LP.

Since the upgrade I'm having a strange problem. When Booting everything works fine, but if I reboot or wake up the PC from sleep mode, it will start using the integrated GPU again instead of the 5060. I've looked into BIOS and the setting for wich GPU to boot on is set to the 5060.

Unfortunatly my BIOS does not have the option to disable integrated Graphics. 

Does anyone have an idea how to solve this?

Best Regards

Hey, try updating your BIOS and GPU drivers first. Reseat the card to make sure it’s properly connected. Then set the RTX 5060 as default in Windows graphics settings. If it still switches back, it’s likely a BIOS issue — update or reset it to fix the detection problem.

Hey, 

Thanks for the quick answer. BIOS and GPU Drivers are up to date. Card is also seated properly and works perfectly fine otherwise. No graphical abnormalities or lacking in performance in any way. Are you sure its a detection issue, since it works perfectly fine when booting form shutdown state? As mentioned above, the problem only arises when rebooting or using sleep mode.

Hey, since it only happens after reboot or sleep and not from a cold start, it’s likely a power state or BIOS handoff issue. Try turning off Fast Startup in Windows and reinstall your GPU drivers using DDU in safe mode. Also, in BIOS, look for any option like “PCIe first” or “Primary Display PEG.” If your board has “iGPU Multi Display,” try disabling it. Some motherboards also fix this after a BIOS update or power cycle. It’s not a hardware fault, just a wake initialization bug between your board and the new 5060.

Got it, that makes sense with what I am seeing. I will try turning off Fast Startup and do a clean DDU reinstall to rule out any driver leftovers. I will check the BIOS again too in case the display setting is hiding under a different menu. Since cold boots are fine, a wake or handoff glitch seems likely. I will test these changes and see if it keeps the GPU active after reboot and sleep.

Did the steps above work for you? I am having the same issue.

Hey, 

I'm sorry for the late reply. I have a chronic illness and didnt feel well to continue on this matter.

Uninstalling the drivers with ddu didnt fix the problem. Selecting NVIDIA as default boot in the bios also didnt fix it because as i found out, when rebooting the 5060 doesnt even show up in device manager or bios.

What fixed my problem was deactivating "intergrated video" in the bios. 

Now reboots work fine. Havent testet sleep mode but shouldnt be different.

No worries at all I was surprised you responded as quickly as you did honestly! I had already tried to disable it in the bios and in the device manager. I didn't get the same results as you.  Maybe it was a combination of the things you had done before guess I need to keep playing with it. Thanks again for your reply.
