Update on this one.. Dell released ~2 weeks ago the updated AWCC (Alienware Command Center) and OC Controls and with those installed I am not seeing my SSSTC Raid-0 freezing during the OS instance as before: it survived the night and in locked screen without BSOD (freezing one of the NVMe m.2 sticks causing the RAID to fail even in the BIOS until a quick reboot resets it). I have yet to test Sleep or Hibernate but am at least pleased I can lock the machine for more than an hour or two and it not break the RAID. Still more testing AND unsure what will happen on subsequent software/driver updates could re-upset the balance but for now its stable. \o/
Environment: x17R1 / 1.5.0 Bios / i9 / 3080 / 64gb at 3467 Mhz RAM / 4Tb 2x NVMe m.2 drives / Win11. Symptoms: Once or twice a day I might be on the system working OR having locked the screen when the machine will completely freeze then crash to that Dell White screen trying to run the troubleshooting OR it will simply say "Boot Media Not Found". Solution: As a temp fix, I simply shut the machine off after this occurs.. it will then bring up the white screen saying "Boot Media Not Found" again to which I shut the laptop down once more, bring it back up, it will at this point likely trying to repair the OS but I just click "continue into Windows 11" then its fine.  What is going on here? Something on the OS causing the UEFI driver or boot media to temporarily kill itself from the BIOS until I shut it down completely (average of twice) then it works again? The laptop freezing and "Boot Media Not Found" issue seems to occur mostly when I lock the screen or sometimes after its shut down over night then 1-2 hrs into using it from there it just stops responding eventually completely crashing to the White Dell Diagnostics screen. Thank you Community! Loving this super laptop so far.. incredibly fast!
