KittyKofi Thanks for the dxdiag, which crashed multiple times while running and is missing a most of its information. This could in theory be a fluke, but it's a good idea to run a couple of basic checks of your Windows system files:
- Hit Windows key-X
- Choose either “PowerShell (Administrator)” or “Windows Terminal (Administrator),” whichever option is offered
- Inside the window that appears, copy and paste “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes, and enter
- The system will start validating soon. If it throws an error, please list it here
- After it reaches 100%, hit Windows key-X again
- Again, choose “PowerShell (Administrator)” or “Windows Terminal (Administrator)”
- Inside the window, copy and paste “sfc /scannow” without quotes, and enter
- Post the message you receive here
Restart your computer, hit Windows key-i, select Update & Security, and click the box to check for updates. If any install, restart again afterwards.
Next, please do a clean uninstall and reinstall of both graphics drivers, as described here:

Use the drivers Dell provides for your laptop. Go here:

Enter your service tag, find your product, and download the newest Intel and Nvidia drivers you see, the latter either for all Nvidia GPUs or for the MX550 or MX series in general.
The proper order of operations is uninstall the Nvidia driver > uninstall the Intel driver > restart > reinstall the Intel driver > restart > reinstall the Nvidia driver > restart, all while your computer is offline.
If none of this helps, please run and post a new dxdiag.
