Hi ZackGreen:
What is your Windows OS [open a Run dialog box (Windows key + R) and enter winver to find the version and OS build number] and BIOS version? To find your current BIOS version open a Run dialog box, enter msinfo32 to open your System Information, and look for the field named "BIOS Version / Date" in the summary.
What is the make, model and current driver version of your graphics device(s) shown in Device Manager? ***
See my 22-Apr-2025 post in KeokiXPS's PCI Bus : Driver Error about these "for information only" Dxxxx and Wxxxx analytical notations that sometimes appear when SupportAssist runs a hardware diagnostic, which are not true error codes. As suggested in that post, run a proper F12 ePSA (enhanced Pre-boot System Assessment) Quick Test hardware diagnostic from your BIOS, followed by an Advanced Diagnostic Test of your Video (graphics), and make a note of any error codes generated by those ePSA scans. If your ePSA scans don't detect any issues it's likely safe to ignore the DW-22 notation from SupportAssist.
The support article How to Run Dell Preboot Diagnostics and Hardware Tests on Your Dell Computer and companion video at https://www.youtube.com/watch?v=inYLxW2_xKo explain how to start your ePSA diagnostics (i.e., restart your computer, repeatedly tap the F12 key as soon as the Dell logo appears, and choose Diagnostics from the boot menu screen). If this doesn't display your boot menu then restart your computer and try again, quickly tapping the F12 key about 2 times every second.

*** NOTE: Your Alienware Aurora R13 support page at https://www.dell.com/support/product-details/en-us/product/alienware-aurora-r13-desktop/drivers lists drivers for both NVIDIA GeForce and AMD Radeon graphics cards. If you click the blue "Identify Device" button on that support page and enter your unique Service Tag the "This Device" tab should list the graphics driver recommended by Dell for your specific graphics device. I generally recommend that users install the hardware drivers recommended on their support page that are certified for their Dell BIOS, since some users have reported issues after installing "generic" drivers offered by the original manufacturer (Intel, NVIDIA, AMD, etc.). See fabioluzo's 15-May-2024 post in their topic Vostro 3520 Keeps Crashing for one example where installing "generic" Intel and NVIDIA graphics drivers caused a problem.
